Cromwell Knob, Lamb Hill, Castle Hill and Bryce’s Plain

Hi all,

Continuing my five day adventure, today (30th of December 2013) saw me tackle three summits in the upper Moroka valley area.

Cromwell Knob VK3/VT-012

Cromwell Knob is accessible via the Cromwell Knob Track. This leaves the Moroka Road at point 905515. It is quite easy walking over about an hour to a point about 300m south of the summit, and then easy to moderate off-track walking up to the activation zone.

I operated from the summit using the KX1, end-fed and the 7 metre pole. A number of operators on the 40m band suggested conditions were down because of a M9.9 class flare the previous day. It was slow going for me, but I was getting good reports from those who I did get. Only two of my four contacts were typical SOTA chasers, and patience is required to get the other two. I really need to learn to use the memory keyer of the KX1, so I can use it for the many CQ calls that are typically made on a SOTA CW activation these days. It was on this activation I thought it would have been nice to have the FT-817 and break out a bit of SSB, although it has been a long, long time that I have had any struggle to get a summit activated with points on SSB.

There are trees on top, meaning that open views are a little obscured, but here is Mt Dawson and Mt Lamb from Cromwell Knob:

I had been thinking of activating these two summits on New Year’s Eve, but due to a bridge closure at Little River on the Moroka Road, it would be a long road walk from there!

Lamb Hill VK3/VT-025

Next up, Lamb Hill. I used the Moroka Range Track to access this. The track starts at 960495, on the south side of the bridge over the Moroka River. I was able to drive the Prius about 700m along the track and then parked the car. I then proceeded south west along the track, then mostly southwards after the track junction at 944478. I left the track at 945474 and proceeded up the spur, climbing to the right once the shallow gully to the right had petered out. Going was easy to moderate off track. This took me up to about 100m from the summit, and well within the activation zone on the ridge. I decided to activate here.

This activation was easier than Cromwell Knob, with more SOTA CW chasers around. It did not take too long to get the required four contacts. The activation again was using the KX1, end fed and the 7m pole. I headed back to the car the way that I had come.

Castle Hill VK3/VT-014

I accessed this using the Castle Hill Rd, through to the Marathon Road turnoff at 006478. I went down the 4wd track for another 400m and parked there. A medium clearance vehicle could continue all along the track to 026482, but I walked this. At this point, there is a picnic ground for the start of the Castle Hill walking track. This starts off well tape flagged, but the track is not really possible to follow on the ground. The flagging tape seems to stop and you are on your own.

I proceeded up the hill (on the south western side of the mountain). There is a 50m or so wide section, where the top of Castle Hill can be accessed without needing to traverse cliffs. Elsewhere, the cliffs form a ring around the summit. Once on top, I made sure I was in the activation zone, but for the sake of time, did not go to the actual summit, which is on the north eastern side of the plateau.

Operation was on a 4.7m lightweight squid pole using the end fed on the KX1. I settled on using the lightweight pole because it fits in my pack without sticking out. I was thinking of doing VK3/VT-009 Mt Darling Range on New Year’s Eve due to the Little River bridge closure on Moroka Rd. That would be a good amount of off track walking, so the lighter and smaller pole would be useful.

The 4.7m pole means that the end fed does not get as far from the ground compared to the 7m pole. Nonetheless, the pole does the job. It does bend over a little, but it has sufficient strength, using the mounting technique that I talked about in this post to bear the end fed in an inverted V configuration. The activation went smoothly.

Here’s a look at the setup at Castle Hill:

With that, it was back to the car and a bit of a drive to my last activation of the day.

Bryce’s Plain VK3/VT-004

There’s no doubt that this is an easy 10 point summit. It makes up for the fact that my next summit tomorrow (New Year’s Eve) is going to be hard. This summit is an easy walk from the Howitt Rd along a track. A moderate clearance Awd would be able to drive to the summit.

I operated going into dusk on the 7m pole using the KX1, and then off to Dimmick Lookout which would be where I would set off tomorrow for Mt Darling Range. A long day, but not too hard after the previous hard two days, and tomorrow was not going to be easy either.

Mt Hedrick and Ben Cruachan

Hi all,

With all of my travel in 2013, I have not had the opportunity for some time to do an extended SOTA trip. An opportunity to rectify this arose over the new year period, so I headed off on the 28th of December for a 5 day trip.

Mt Hedrick VK3/VT-069

This is a summit that has not yet been activated. Looking at the festy.org maps, there is a walking track marked that goes from Huggetts Rd up the western end of the mountain. Opencyclemap also has it marked, but starting a few hundred metres to the north. Both tracks exist, although the opencyclemap starting location is more official. There are some nice views on the way up:

Looking north from Mt Hedrick's western slopes

Looking southwest from Mt Hedrick's western slopes

Looking southwest from Mt Hedrick’s western slopes

Operation from the top was using the KX1 with the end fed on the 7m heavy duty pole. The top has trees, and no nice views were obtainable. The day was clearly going to be warm, so I did not stay long.

Ben Cruachan VK3/VT-042

To access this, I attempted to head up Ben Cruachan Rd. In Forest Explorer, it is marked light red, meaning it is a more significant road. Nonetheless, the road ended and entered private property at 806131. The other maps also gave little indication that this would be the case. Because of the colour marking, I did not look at the land.vic.gov.au maps to see if there was a road reservation. Nonetheless, I had to turn back.

Next up was to try Gegghegans Rd and Beaver Medows Track and see how far I could get. I got to about point 783132, which was still a long way from the summit. It was going to be a long walk today. I filled up the water bottle, grabbed some food and started walking.

After a few climbs and rest stops, I realised that the full water bottle that I had taken was not going to be enough water. I had taken 1.5l, but I really needed about double that. I was quite tired when I reached the summit. The summit itself has good views, but through the trees.

Looking north from Ben Cruachan

I operated again using the KX1 and the end fed on the 7 metre pole. Some of the usual CW chaser suspects were not around, however the 4 QSOs were obtained without too much difficulty.

I did not want to stay too long, because it would be a 3 hour trip back, with only a small amount of water. I had to ration this to last most of the trip. I was very thirsty when getting back to the car. Because I was quite dehydrated by this stage, I started only drinking small frequent amounts, rather than shove a whole lot of water back in. Still, in the 3 hours after getting back to the car and before going to bed, I downed another 3 litres of water.

Day 1 of the 5 day trip down, 4 days to go. Next on the agenda was VK3/VT-064 on the way up to Licola and a difficult day trip up to two summits including Mt Margaret.

Mt Concord and Proctor

Hi all,

While the rest of the family lazed around during a camping trip, I decided to have a day on the hills. I selected two nearby summits that had not been previously activated.

Mt Concord VK3/VN-018

This summit is at the southern end of a long ridge that can be seen from the Maroondah Highway on the way to Mansfield. Many SOTA activators will have gazed on this range on their way to higher hills in Victoria’s north east. It was now time to get this summit activated.

The summit is on a road reservation. This is not fenced. I used Nicholsons Rd from the highway for access. This is a high quality gravel road until point 738904. It is a bit rough from there, but still worth going up about 500m or so. From here it begins to climb quickly. I proceeded on foot. The formed road goes off to the left onto private land. The road reservation, plus the public land of Molesworth Bushland Reserve to the right gives access up to the top of the hill. It means leaving the formed road at the gate into the private land and continuing to climb to the right of the fence. Its a climb of about 350m over about 1200m, so it is quite steep. I didn’t mind the steep climb, as I had a series of tough activations planned in the following week.

I had also loaded a detailed map from land.vic.gov.au to show the location of the road reservations. From the top of the climb, it was clear that the road reservation was not fenced, instead one of the two land owners was using it. From the map, it was the farmer to the west, rather than the pine plantation to the east. So, I stayed to the west of the fence and proceeded southwards towards the summit. There was a track on the wrong side of the fence, but I stayed away from this due to this being likely on private land.

The summit itself has a trig point and I operated from there. I used the 7m heavy duty pole to mount the “random wire”, but had more success with the end fed. I suspect that my wire direct to BNC connector is perhaps not the best approach as it is subject to load. Instead, I want to look at a BNC connector where I can screw the wires in.

There were some nice views from up on top.

There were no real views to the east because of the pine plantation.

Mt Concord has a limited life in the Summits on the Air program. The summit is actually 647m high, not 697m. There is another spot to the north that is higher on this plateau system, and it will be the replacement of Mt Concord in due course. This won’t be for a while as it is not in the current round of summit changes.

Proctor VK3/VN-019

Proctor is located south of Bonnie Doon to the west of Lake Eildon. I accessed it from Alexandra and the road into the Frazer section of Lake Eildon National Park. Skyline Rd skirts the western edge of the park. Proctor is located to the north of the park, and there is good 2wd road access into activation zone. I setup in part of the road reservation and again used the end fed antenna on 20 and 40, using the internal ATU of the KX1 to tune for 30. It did this quite easily.

Conditions were mostly fine, apart from a sharp shower that came through. I continued operating through the shower by putting the rig underneath my backpack. One does not need to see too much when keying CW. I lent over the (paper) notebook to keep it from getting wet. The shower was short and then it was back to fine sunny conditions.

Mt Misery, Mt Kooyoora and Mt Bealiba

Hi all,

Up in Ballarat for a few days with the (out)inlaws. Without implying anything, its nice to slip away for a bit of SOTA action, especially to gain some new uniques.

Mt Misery VK3/VS-024

This is a summit that I have had my eye on for some time. It can be seen easily from the Western Highway between Ballarat and Ararat. Allen VK3HRA had activated it last year, so I was keen to follow and get it in the log. I gave one of the owners a call, and gained permission.

Access is via the Beauford-Waubra Rd. Stop at the Mt Misery Quarry sign NNE of the summit. You need to have arranged permission to proceed beyond this point. If the gate is open, don’t just enter anyway as you might find yourself locked in – which might be a problem if your car is on the wrong side of the gate, aside from the SOTA rules.

I met Chris, one of the owners, on the day. He is an old time farmer who doesn’t farm any more. He runs a fencing business but is looking to enjoy life a bit more.

I left the Prius near the hut about 300m NW of the summit. Chris was spending time working on bikes nearby. From there it was a straight forward climb up to a knoll to the west of the summit, and then a short steep section to the summit itself. There’s a trig on top and I operated from there.

The antenna tuned at the bottom part of the 40m band, so I operated from there. 40m on CW in VK is getting reliable enough for 4 SOTA contacts fairly quickly. I also operated on 30 and 20, which give better access for VK5 and northern VK2. I was hoping for some DX, but not today.

On a clear day, a lot can be seen up from here, so Chris tells me, and I have no reason not to believe him. For today, there was a nice view of inversion clouds at Mt Cole.

Mt Kooyoora VK3/VU-007

I had first planned on doing this summit on a trip in July, but it was not to be then. The forecast for today was for showers and for conditions to be cooler. This was a good thing, because while Ballarat was 20 degrees today, here was 30. The showers did not really happen either.

I accessed from Mount View Rd from the south. Turning left off this at 409472 allows a short drive up (turn left at the next junction) to 1100m from the summit at the Crystal Mine carpark and its mostly off track from there heading northwards. The land falls for a few hundred metres, but not much. It then climbs up about 120 vertical metres to the summit. It is fairly easy off track walking. A big squid pole can be a mild annoyance, but I’ve took my 7m pole through far worse than this.

The antenna preferred to tune at the top end of 40, so I operated from there. It was nice to get a s2s with Peter VK3PF, but it was Xmode to get it. Seems funny to send a 59 signal report using CW, but I thought it better not to try to rate Peter’s voice tone – what would we rate it on? 1 for really angry to 9 for really happy?

Ian VK5CZ sent me a photo of his outdoor operation, so I sent him a photo of the shack:

Operating at Mt Kooyoora

The 7m pole is nice, but it does not really add a whole lot of antenna improvement vs operating on the lightweight 4.7m pole. I think what I will do is plan to use the 7m pole where I am expecting either a walking track or easier off track access to the summit, and take the smaller pole where more challenging walking is expected.

I also might prepare a 1/4 wave counterpoise for 40, but I might only take it and use it where using 7200 to 7300 is expected to be an issue – eg where a band plan either discourages using CW there, or the band plan has the force of law and prohibits it, or it’s a country that does not have 7200 to 7300 at all (eg the UK).

It’s a lot browner up here than last week in the Victorian High country:

Mt Beiliba VK3/VN-026

Last summit of the day was Mt Beiliba. Last time I was here, it was also the last summit but it was pouring with rain. Thought I better leave it. Now, conditions were far more pleasant.

In accessing this summit, it pays to have a good map. There are many roads in the State Forest area that go all over the place! Good access can be had by taking the Beiliba range track turning left off Log Bridge Trk at 354234 and then turn right at 353231. I tried taking Log Bridge Trk further, but ended up parking at 346233, which left me a 350m easy off track walk on very open forest to pick up Beiliba Range track, just as it started to get steep. No matter, it really just cost me 350m as there is no way I would the Prius up the steep section. I would think a low range 4WD would be required.

There are two high points, Mt Beiliba and a point north of there, about 400m away. All of it is in the activation zone. I actually went to the designated summit and operated from there.

As par for the course, the antenna liked the top end of 40m more. There is enough interest to get a CW activation done on weekends quite quickly on 40 these days. It feels much better than even the early days of SSB SOTA.

With that, and late for dinner, time to go home.

Mt Buller and 4 other summits CW only

Hi all,

After building a “random” wire antenna, it was time to take the new configuration on activations and see how it works in the real world. I decided to leave the FT-817 at home and go cold turkey on real CW only activations, with no capacity to fall back on SSB to ensure I got four contacts.

I don’t have a great deal of spare time these days, so I thought about going up on a Sunday afternoon and pull a flexi time off day on the Monday. If I’m going to jump in the deep end CW only, this is a way to do it when there are fewer SOTA chasers available during the week.

VK3-VE123

This is an unnamed summit accessible from Timbertop saddle on the Howqua Track. Three Chain Track heads off to the west. I was able to get the Prius up part of this and called stumps (a cricket term meaning the end of play) about 1.5km from the summit. From there, I headed on foot.

The track would be easy going in a proper 4wd.

For this activation, I still took a bit of a safety net, with the end-fed antenna on board and I took up the 7m squid pole. I decided to employ the “random” wire on the 7m squid pole.

The KX1 was able to tune on 20/30/40 with a very dodgy tune on 80 for interests sake. The rig reports the power after the tune. Compared to home, I was using a set of 18650 LiIon cells which develop 12.6V fully charged, but quickly drop down to mid 11’s. At this voltage, 2.5W would be the best I could hope for. Practical KX1 activations are lower powered than FT-817 activations where 5W is easily obtainable.

Power is lost across the tuner, depending on how difficult the match is. I was developing 2.2W on 20, about 1.7W on 30 and about 1.3W on 40. The tuner was effectively losing about 3dB on 40, but less on the other bands. SWR was 1.5 or less.

There’s no real risk of a CW pile up on a SOTA activation in VK at this stage. I had a range of contacts from local to DX and across all three bands.

One thing cropped up. The KX1 paddles are a little loose in their socket. I would tighten the hand screw to help, but even so, there would be some movement on the paddle base and this affected my keying. Ian VK5CZ got the worst of it, so much so I noticed after I got home that he suggested going down to 12wpm. Slower keying would not have helped in this case, it would have actually made it worse.

I found the solution to this problem would be to hold the base of the paddles with my thumb of my non keying hand. This seemed to make keying much more reliable, with only the occasional missed formed character.

Its not the same as my touch keyer, which does not lose a beat. However, the touch keyer needs its own battery and is liable to be turned on in a backpack. This can flatten it over time (takes several days). I think I will learn to live with the KX1’s paddles.

The activation was at dusk, so it was too dark to take photos of the setup. It was a nice sunset to look at though.

Mt Timbertop VK3/VE-073

It was back to Timbertop saddle where I slept. Next morning, I took the walking track from here which goes up the mountain. This track has been upgraded from going straight up to a track that does some zig zagging. Makes the track more pleasant to walk on. In a few places, walkers are trying to use the closed track, but I don’t think it would save them much time – apart from being harder.

There are some great views looking west.

The summit is reached quite comfortably. This climb is easy if one is fit. If you are not, you need only take your time. A walking pole is of great assistance.

The summit itself has some snow gums (Timbertop suggests there should be some timber on top). I decided to put the KX1 in a tree so that the base of the wire is not near the ground. This seems to help 40, but does not necessarily help, perhaps hinders on 30.

For this activation, the 7m squid pole was left in the car and my 4.7m squid pole was brought along instead. This pole, discussed in this post, is very lightweight. 20m and 30m worked fine, but I found I had better tuning results on 40m if I tuned for near the top of the band, around 7.28 to 7.3 In VK, operating CW here is fine, although somewhat unusual. To get some contacts, I operated down the bottom of the band, but with SWR around two. The power was around 0.8W verses 1.2W at the top of the band.

I was wondering if the squid pole would be strong enough at my chosen mounting point about midway on the second highest segment. The squidpole looks like it does fine at this point for the sloping wire of the antenna. I’m not sure about mounting my HW end fed on it because that wire is much heavier.

Mt Buller VK3/VE-008

Most local readers would be aware that Mt Buller is the location of a significant winter ski resort and has also developed into a summer mountain bike park. The development of this mountain means that there is a sealed road most of the way to the top, then a short gravel road. There is only a 50m vertical climb to the top. I operated a little down from the actual summit, about 30m horizontal or so from the top.

I operated with the lightweight setup again on this summit. The KX1 was reporting about 11.4V from the battery. It seems it takes about 0.5V off the input voltage. I tried this at home with really fat cables on a 13.V supply and the KX1 reported 13.0V. I tried it at home with same thinner supply cable and it still reported 13.0V (alternating a little to 12.9V)

The setup is shown below. The lightweight squid pole can be wedged in some rock with tension on the cable holding it in place. It was windy up there – the picture shows some wind load on the cable.

VK3WAM station at Mt Bullder Vk3/VE-008

VK3WAM station at Mt Bullder Vk3/VE-008

The KX1 developed about 2W on 20, 1.6W on 30 and 1.1W on 40. 40 needed to be at the top of the band for an acceptable SWR. Down the bottom was a SWR of well over 2 and a power of only 0.7W.

All contacts at this summit were on 40. Peter VK3PF tried his hand at some CW, which was certainly good enough to read his reports, with some initial confusion on his call sign. Given that he, along with Gerard VK2IO had not done CW for extended periods, SOTA is having an impact on use of this mode. Perhaps motivated by wanting to work the summit and knowing that CW was needed to active this, helped them dust off those long unused keys!

The operating spot gave a good look down the steep NW face of Mt Buller. Apparently some people have tried skiing down here. There was a sign nearby with two sets of double black diamonds reminding skiers that the area was unpatrolled.

Mt Stirling VK3/VE-011

From Mt Buller, there is a road that goes to Howqua gap, but I was not prepared to drive down that in a Prius. Instead I drove down the mountain and then up the Stirling Rd. Mt Stirling is surrounded by a circuit road, but this does not approach the summit closely. I decided to use the River Spur track. Its a walk of a little over 3km, with a climb of about 400m up to the summit. It can be accessed by using the southern side of the Circuit Rd – the first track heading up is Bluff Spur track (over 4km) with River Spur track being the second track heading up.

The summit is above the tree line. I used the trig point to mount the squid pole.

Operating at Mt Stirling VK3/VE-011

Operating at Mt Stirling VK3/VE-011

The trend of 20 and 30 tuning quickly and 40 being better at the top of the band continued here. The battery voltage was reported about 11V, and power levels were 2W, 1.5W and 1.1W on 20, 30 and 40 respectively.

Even though the KX1 is only developing 6dB less power, with the tuner, on this configuration on 40, it is enough to get contacts. The setup is very lightweight and very fast to put up and take down. If I was to take the larger squid pole, with the end fed on a FT-817, that might give me another 12dB with everything, but it is significantly more gear to take. The nicest thing about the KX1 is it is a complete station, with the antenna. I’m using it with an external battery, but it does have the capacity to put some internal AA batteries inside.

I was able to activate with a mix of 20 and 30 contacts. I saw later on SOTA spots that N7SP was trying to get me on 20, but looking at messages others try to send using SOTA spots is not always easy on summit.

Most of these mountains have great views on top and Mt Stirling is no exception. Here’s a view back to Mt Buller:

Mt Winstanley VK3/VE-036

The last summit on the menu was Mt Winstanley. This summit is to the north west of Stirling, so I used Circuit Rd and then No 3 rd to access it. Here’s a screenshot of the tracklog:

Tracklog of access to Winstanley

Tracklog of access to Winstanley

There is a track going along the ridge – and this is shown in opencyclemap. It is not in the Forest Explorer or the OziExplorer maps that I have. I used the track for the last 500m. Opencyclemap does not show RazorBack Trail correctly, but this track departs near the junction of No 3 Rd and Circuit Rd. Going up RazorBack and taking the walking track, I presume, from there is likely the easiest route to access this summit.

Spot the station – including the squid pole – in this photo:

Operating at Mt Winstanley

Operating at Mt Winstanley

The KX1 reported a battery voltage of 10.7V. This would be around 11.2V out of the battery. This would be a little less than half a cycle on these batteries. They are fake Ultrafires, branded for 2400mAh capacity, but actually give about 1200mAh. It would appear that the KX1 drew about 500mAh to 550mAh, for around 7 hours of operating, including lots of CQ calls.

At this lower voltage level, I was getting about 1.8W on 20, 1.4W on 30, and 1.1W on 40. Interestingly, 30 did not like the KX1 a metre and half off the ground, I got a much lower SWR on the ground – power levels were similar. 40m liked the rig off the ground, but again, tuning was better at the top of the band, where tunes were getting an SWR of 1.1 and power of 1.1W, compared to SWRs of 3 or higher and power of less than 0.7W on the ground.

Can I improve the performance of this antenna – undoubtedly yes, but why bother. If I want something better on 40, I’ll carry the half wave end fed, with its matchbox. If I improve this “random” wire antenna for 40, it will come at cost of lower convenience, because the improvement would need to be a 1/4 wavelength counterpoise for 40m. As it stands, the two counterpoises do a good enough job for the very lightweight and portable objectives of this wire antenna. 40m is an important band for local contacts, but I think 30m will rise in importance as nearby states become more accustomed to SOTA. I think, in time, that 30m will be an important band for SOTA in VK.

Preparing the KX1 for SOTA battle

Hi all,

Elecraft KX1

A few months ago I picked up a KX1 from a EDMRC club member who was selling. The unit came built and fully equipped, with the inbuilt ATU, the 30 and 80 band board and the keyer. The KX1 is a CW only rig but designed especially for portable use. With my mountain goat status out of the way, I wanted a CW specific and more light weight setup.

Rik VK3EQ (VK3KAN) had shown me a very lightweight squid pole at the 2013 Gippstech. I was quite interested in this because it packs up to 60cm in length. It has a 4.7m length when extended. Perhaps the top segment is too light duty to hold anything but a vertical wire, but the next segment down should handle at least a lightweight inverted V configured wire.

Random length wire antenna

Elecraft recommend that the KX1 ATU unit be used with “random length” wire, so long as the wire is not 1/2 wave length on the desired band. Note the reason for this is that the internal tuner is not always able to match the high half wave impedance.

I decided I wanted something serviceable on 20/30/40. After looking around at various web sites, such as this one, I settled on a 41 foot or 12.5m wire length. This is more than 1/4 wave length on all these bands, and around 5/8th wave length on 20. Should be a good “Aussie allrounder” but performing best on 20.

I bought some cheap speaker wire from a hardware store for construction and separated the two wires, but keeping the insulation. I stripped back some insulation at one end and doubled back to crimp a BNC pin. I then made two lengths of wire from the spare speaker wire for a counterpoise. One is 1/4 wave length for 20, the other quarter wave length for 30. 40 misses out, but at least both the counterpoises are 1/8th wave length or longer for that band. I crimped one exposed end of each of these to the shield on the BNC connector.

To give some mechanical security to the BNC connector, I taped about 7 or so cm of the three wires together, starting at the crimp. At least at this early stage, it seems to work well. We’ll see how it goes in the field.

The idea with this antenna is that there is no feedline. The antenna begins at the BNC connector – it is literally being fed right out the radio. The other end of the wire could be put up a tree and/or having the other end or middle of the wire on the squid pole. The counterpoise wires go on the ground.

Mounting the wire on the squid pole

For the squid pole, I cut a small wood mount piece with a 1.5mm hole for a wire to use to wind the antenna wire around. I drilled a 3.5mm hole to mount the piece on the squid pole. This ends up about half way on the second highest segment. The top segment would be too weak for this kind of work, I think even only the bottom half of the top segment would be strong enough even for a vertical only wire.

It sits on quite nicely.

The wood mount is quite small:

The piece is small enough to be packed up in the squid pole case cap. The squid pole itself is small enough to go inside most larger packs, and even 40l hybrid type packs.

A basic test suggests that the squid pole will be able to keep the wire up in the field. We’ll see. If need be, I just need to make the hole a little bigger and it will mount a little lower on the pole.

Testing with the KX1

My initial test was at home. My house is two story, but the upper story can look down on the lower story. I draped the wire from upstairs to down, with the two counter poises on the floor upstairs. Not the best setup, and looking forward to trying it in the field.

The KX1 was able to tune the antenna on all bands, although the result was emergency use only marginal on 80. SWRs were 1 to 1.1 on 40 and 20 and around 1.5 on 30. The KX1 also shows realised power from the tune – which is quite interesting. The 20 match was showing full power (about 4 watts), with the 30 match around 2.8 watts and the 40 match about 2 watts.

I would expect better results in the field when this antenna is setup properly, with the random wire fully extended and the counterpoises at a greater distance from the wire and fully extended on the ground themselves. We’ll see, but none-the-less, early results look promising.

The whole system weighs less than 1kg, including the squid pole. It is my most light weight setup yet. If not for the squid pole, it could even get close to the station you can carry around in a pocket (or two).

I’m keen to give this a go on a SOTA summit or two over the next few weeks. Perhaps the FT-817 and the bigger squid pole and end-fed will come along as a safety net to make sure if this falls over, I’ll still be able to activate.

3 summits and Mountain Goat

Hi all,

After last weekend’s effort I was on 985 Summits on the Air activation points. 1000 points is the level of the pinnacle activator’s “Mountain Goat” award. I had been quite busy recently, but I was keen to finally get enough points to become eligible for this award.

Some time ago, I had identified three summits, including Mt Duffy, as suitable for an activation, but due to fire burning, there was no available access method. Now, the 18 points they offered would be enough to get Mountain Goat.

Point 951 VK3/VN-010

First up was the northernmost summit. I headed up the previous evening and the plan was to sleep in the car. I would access via Gum Top Rd which passes over Mt Duffy. Gum Top Rd branches off Eildon-Warburton Rd at 093102. It is quite passable in a 2wd. The road generally follows the alignment as shown in Forest Explorer, except that the road does link up through to Mt Duffy at the Harry’s Track junction. OziExplorer maps show the link. I was able to get the Prius through quite easily in after dark driving. I continued onto Dray Track. Again, this section is passable with care in a 2wd. There is one steep descent (ascent coming the other way). It did not look too steep going down, but we would be finding out coming the other way later!

I proceeded to point 163558, where a 4wd track comes down from VK3/VN-008, and setup the mattress and sleeping bag in the back of the car. The 2004 model Prius has just enough room back there with the back seats down to fully stretch out.

Next morning, out with the pack and up to VK3/VN-008. There is no track marked on Forest Explorer, but OziExplorer shows the alignment. There is a rougher track heading down the north east side of that summit, and then it climbs up the VK3/VN-010 hill to point 182568. From here, head along the ridge. There is a very old overgrown track here. Keep to the centre of the spur, and it will be picked up fairly soon. This old track makes for easier access for the last 500m to the summit.

I arrived and started activating at around 8am. People are still getting up that time of morning so there was no big pile up. It was still a comfortable activation. These days with an efficient setup, there is no endless calling on 40m and not getting anything, if the band is at all open.

Here’s the end fed antenna at VK3/VN-010:

Access to this summit was simply retracing my steps back from VK3/VN-010. Back to the track at point 182568. Oziexplorer shows this track continuing down the hill to the nor-northeast but it looks very overgrown. I headed back down the steep hill and climbed up to VK3/VN-008. I operated from the track, mounting the squid pole against some saplings from the 2009 fire.

Signals here were up on VK3/VN-010, but it happens as band conditions change. With a good cloud warming end fed on 40m on a 7m squid pole, conditions have to be pretty terrible on 40 for there not to be any action.

There was also a moderate pileup. SOTA activations during the week still have plenty of chasers.

There were good views of Mt Torbreck VK3/VN-001:

I also could look over at Mt Duffy, the site of the third activation. Mountain Goat status awaits!

Mt Duffy VK3/VN-007 from VK3/VN-008

The final activation was at Mt Duffy. I got back in the car and headed generally southwards towards Mt Duffy on the Dray track. It was good going in the Prius, but the steep section awaited. I anticipated I would need a good runup. The Prius generates a lot of torque at low speeds with the electric motor, but this is not always a good thing as it causes the tires to spin, then the anti-skid control cuts the power. Makes getting up hills challenging. I needed to get the car up this hill, considering I came down it the previous evening. I was able to get up without too much trouble on the first attempt. After that, easy going to Mt Duffy. I parked the car in the activation zone about 200m from the trig point. I then headed down another road and came up an old fire break to the trig point. There is a little bit of controversy about “final access to the summit” being non-motorised, and what does this mean, but I like to leave the activation zone and re-enter it with all my gear non-motorised. Of course I note the SOTA MT’s concession to people with mobility disability not needing to do that, and I’m ok with that.

Anyway, I setup at the trig point. Before starting the activation, I took a video:

We also have some MP3 audio taken by Matt VK2DAG of the activation:

With the activation done, it was back to the car and out on Gum Top Rd. It is easier going back to Melbourne via Marysville rather than by Warburton.

The SOTA 1,000 points does take a lot of effort in VK3. Many summits I’ve activated have been in the wilderness. While this means they might take a lot of effort, it only magnifies the fun. SOTA might seem an odd activity to some, but the comradely with other activators and SOTA chasers has been great. I look forward to many more SOTA activations in the future.

In recent months, I have been too busy to be able to do the multi-day pack-carry SOTA adventures that I have done in the past, but I look forward to sneeking in a few of these over the summer months.

I think with the Mountain Goat achieved, it might be time to shift gears a little and perhaps go back to a bit of 2m colinear usage, or perhaps brave taking out the Elecraft KX1 for CW only activations!?

Mt Buangor, Ben Major, Ben More

Hi all,

This weekend I had the chance to get out and have a look at a few summits. One, Mt Buangor was one I visited last year, but the other two were firsts for me, with one being the first ever SOTA activation.

Mt Buangor VK3/VS-003

This summit is quite easy to get to, even with a 2wd. The main Mt Cole Road passes within a few km, and the first turnoff road at 982712 is still an improved gravel surface. It climbs up to 979707. From here, the road is of lesser quality as one turns right and then left 150m or so further along. It is passable in a 2wd, but only if dry. On this occasion, there were two large puddles, the second of which I was not prepared to drive the Prius through. A Awd should handle it pretty easily. Even so, it was less than a 10 minute walk from here to the summit.

This year, it was out with the end-fed, the tried and true method of getting a quick activation. FT-817 in hand, I operated for about 20 minutes. Signal reports were a little down, but no real problems. It was good to be back on air after more than a month!

Ben Major VK3/VS-028

Onwards to new territory for me. I headed down the Mt Cole Rd to Raglan and then along the Chute Raglan Rd to 113695. Turning off to the right, there was a track, quite passable in a 2wd heading towards Ben Major in the state forest. I made my way along this to 142713, where I turned left. The road quality here was worse, but still passable with care in the 2wd. I made my way to about 500m shy of the summit and walked up about 50 vertical metres from there.

There was a trig point at the summit which I set up from:

Conditions on 40m seemed to have picked up here from Mt Buangor. Reports seemed to be 3 or so S points higher, both on Rx and Tx. Same general setup with the end fed.

From here, there was a good view towards Ben More, which was my last summit of the day.

Ben More VK3/VS-027

Ben More is slightly higher than Ben Major. There is a public park that approaches the summit itself, but does not quite make it. The summit appears to be on private land. The top part of the public land is well within the activation zone, about 5 vertical metres down.

The next trick is that there is no easy public access to this summit. There is, however a public road reservation that makes its way to the public park boundary. I communicated with Rob Brouwers, a ranger at Parks Victoria Maryborough office. He can be reached on 5461 0819. He highlighted that Impeys Rd then Joseph Lane continues to make its way further than marked on most maps and the reservation goes all the way to the Ben More Bushland Reserve. Along the way, the road goes through a gate with “Private – No Entry”, however the road reserve that continues past this sign is public land. If planning to activate, it may be useful to get in tough with Rob and get the access map emailed from him as to how to access the reserve.

A quick side note: Google maps shows the approximate line of the road reserve. There is no road for the last 1000m of this alignment.

The road ends up about point 172770. From here its on foot with the land climbing steeply. It’s just over 1km, however about 250 vertical metres, so get ready for a climb. Using the land boundaries map obtainable from Rob, you can aim to keep within the public reservation and try to prevent going onto private land. The road reservation is largely not fenced from this point. The boundary of the bushland reserve higher up is, and once in there, it is still a steep climb, but a little easier as you can more freely choose your climbing line on public land.

I operated about 20m from the trig point. The trig point itself is on private land. The closest public land is quite close, and I used the emergency marker there to mount the squid pole:

With that, it was time to pack up, head back down the hill and carefully try to stay within the road reserve back to the car. It was a nice activation, but I felt it was important to have the Parks Victoria documents with me in case someone decided to challenge me being there.

Mt Saint Phillack and Talbot Peak 2013

Hi all,

It was off to the hills again on October 5 with an attempt to pick up some late bonus SOTA points before the end of the bonus point season. I chose Mt Saint Phillack VK3/VT-006 and Talbot Peak VK3/VT-010 as two 10 pointers that could be done together.

Mt Saint Phillack VK3/VT-006

It had been quite windy in the lead up to this trip and I was concerned that access to Saint Gwinear might be prevented by fallen trees. Clearly a number had come down but had already been pushed out of the way. I think I need to bring at least a handsaw in future just to give me a few more options, especially if a tree falls down during the day to prevent you from getting out again.

Conditions were warmer this year than last, even after recent snowfalls. There was no snow at all at the car park, with patchy snow seen up top. It was still only patchy at the summit. I headed up the main trail from the car park, using the Gwinear bypass. There was basically no snow on the track until up on the plateau.

It was also far more pleasant operating this year than last. There was the possibility of a few showers, but conditions stayed sunny for most of the time.

Talbot Peak VK3/VT-010

With conditions quite open, I decided to head to Talbot Peak directly from Phillack using the Alpine walking track (AAWT). The track falls down below 1300m between the two peaks, and there was no snow at all at the lower altitudes. The track was still quite wet from recent snow melt. I was wearing only light runner style boots, so these got quite wet. These days, I avoid boots unless I am going to be carrying a decent pack, or I expect conditions to be sporting enough to consider using gaiters.

It was good progress to Talbot Peak. It had patchy snow, like Saint Philliack. Again I went for a quick 40m activation on SSB. I met a few groups coming through from the Mt Erica car park, so clearly the road through to there was still open.

With that, it was time to head back to the Gwinear car park and an easy run out. A nice day for 26 SOTA points. I got a nice open view of the Thompson Valley on the way out, which was a nice contrast to the clouded in experience last year.

South Gippsland and Mt Matlock

Hi all,

Continuing to catch up on this blog.

VK3/VT-029

I was heading off on a three week trip to PNG, and wanted to sneak in a few SOTA activations beforehand. On the evening of the 5th of September I headed up the Woods Point Rd to the Thompson Jordan Divide Rd. This is a good 2wd road. I headed down to point 307297 and slept there the night.

Early the next morning, I passed through the seasonal closure gate on foot. It’s about 6km from the road junction to the activation zone. The track from here would be quite passable, perhaps even by a 2wd during summer or in dry conditions. The summit is quite unremarkable, perhaps Mt Easton, a few kilometres away, might give some views of the upper end of Thompson Dam.

Station at VK3/VT-029

There are not as many SOTA chasers during the week, especially early in the morning. It was never a problem getting the number of QSOs, but not the fast pileup today.

With that, it was back to the car and onto the next summit.

Mt Matlock VK3/VC-001

This mountain is in the central region. It perhaps does not belong, but because the associated local government area stretches out this far, central region it is. Last year, this summit was covered in snow, but it was a more civil affair this time.

Summit of Mt Matlock

It is quite possible to drive a 2wd all the way to the top. I left the car at the road junction about 300m south of the summit, then dropped a bit of height and walked up to the summit from there.

The activation was still a little slow with eight contacts. Not too many chasing today.

As I was able to drive further than expected, I was now getting ahead of my expected time schedule. Nice to keep a bit of time up my sleeve.

Mt Toorongo Range VK3/VT-026

Next up, Mt Toorongo Range. Many have been here since I was last, this summit seems be a quite popular place during bonus season.

I was able to get the 2wd all the way up to the seasonal closure gate. From here, it’s a fairly short walk. This time, I headed up to where the road levels off, and then head off track up to the summit. Easier going than last year.

Activity from here was a little busier than my previous two summits. This year, I was only doing 40m unlike last year where the colinear had a go. Finally, I had a look from here at the final summit of the day.

Mt Horsfall from Mt Toorongo Range

Mt Horsfall from Mt Toorongo Range

Mt Horsfall VK3/VT-028

The main road going to this summit is subject to a seasonal closure quite some distance from the summit. My plan was to approach it from the south and use a 4wd track that goes up the side of the mountain. I had heard that others could not find this track, so perhaps it does not exist – it would not be the first time a marked track does not exist.

I used the Toorongo Rd from the link rd, travelling west to about 2km south of the summit. There was a track heading up from here, so I drove the car up. It was a little rough for a 2wd, but I travelled up about 800m to another junction at point 168183. From here, I tried heading north-east, but that track died out. I then tried the other track, and the tracklog is shown below:

Access to Mt Horsfall

The track starts off quite good, and makes it’s way across a creek. From there it winds up towards a lookout for a waterfall. The track is quite overgrown going through the zig zags, but still worth following. From near this lookout, I made a direct line towards the summit, going straight up. The forest is mostly passable, there’s a few tricky bits to try to avoid. I also picked up a leech or two, so wearing gaiters is a good idea. The off track section can be as short as 700m, so it is not too bad.

There are some good views up top, overlooking the forbidden forest of the Upper Yarra.

Even though there were a few clouds around, the rain held off until I was back in the car and driving home. Nice one 🙂

Due to the large grassy area, I chose to use the trig point to mount the antenna.

The end-fed is the ol’reliable. It, again, was not as busy as a weekend SOTA activation, but lots of good strong signals.

With that, it was time to head for home. Back in the car, well before dark.
