SOTA station storage

I’ve been inactive for so long so it makes sense that the most streamlined part of my station is the storage…

Recently repacked after yesterday’s activation of Federation Range:

In there is everything required except for a squidpole and batteries.

  • FT-817
  • MTR3b with single lever palm key.
  • Decent whip for the H/H
  • Charger and various cables including crocodile clips
  • ATU
  • 88ft doublet
  • 3 band trapped EFHW plus matching unit.
  • 20m GP
  • Multi-band homebrew (ARRL home brew comp design) 80-20m amp
  • 10m 1/2 wave vertical
  • Various lengths of rg-174/rg-58 coax
  • Miscellaneous bits like pencils, pens, pencil sharpener, leatherman like tool, straps and lengths of cord.

80m station complete(-ly untested)

On a whim I bought the QCX kit for 80m thinking to compliment the 40-30-20 MTR. The only problem was antennas. My goto choice up until now has been an EFHW of some kind which gives adequate performance in a small light package. Rebuilding for 80m was one option but more sacrifices would need to be made than I was happy with.

I settled on a 88ft Doublet fed with some of the very light 300ohm tv line I also bought 6 years ago during a clearance sale thinking it might come in usual one day. Idea of using a pool noodle as the winder came from KK4NQQ on the Sota reflector

The ZM-2 was a Christmas present to myself.

All put together in time for the Mt Hotham weekend…

I/AA-039, I/AA-053

I researched the summit possibilities in the area we were staying for New Years and quickly packed the MTR away in the cupboard… no no and no… it’s pretty much all like the the following:


Piz Boe I/AA-341 on the left hand side below, might be easily accessible in summer with a hike from the cable car (behind). Activated 8 times.

Finished QCX

Work has kept me stupidly busy this year… the only project completed is a build of the QCX kit from QRP labs (and a new trapped antenna for the MTR). Built for 80m to complement the 40/30/20 MTR3b and provide a morning NVIS option.


The case was custom build out of 1mm Al using a home made brake and follows the design of the LNR Precision MTR case. 

Sensitivity seems fine and puts out 3.8W on 80M on initial measurements. Now I’m only missing an antenna…

Arthur’s Seat VK3/VC-031

I’ve driven up Arthur’s Seat a few times, run up it more than a few times, and driven past it even more often. Still hadn’t got around to activating the thing…

I rarely take part in the VHF field days as a proper contestant, but I often use it to test out my 23cm station. I’m also keen to reward those who put the effort in and head out with decent stations. If I remember, I usually try to give out a few contacts, mostly on the higher bands.

Arthur’s Seat has a good takeoff to the south, west, and north depending on where you set up so, despite the trees, is not a bad place for UHF/Microwave work. Especially nice are the numerous picnic tables.

I was headed down the peninsula to meet up with some other members of our astronomical society and had just enough time to squeeze a single band activation in on 23cm.

The easy and smart way to do 23cm is to liaise on a lower band to establish beam headings, but there is a particular joy in getting random QSOs on this band. My 10el Yagi has a very broad beamwidth anyway.

Because I had no intention on entering the contest, I put a spot up on sotawatch. About 10 minutes of calling later I was rewarded with a QSO with Andy VK3VKT, followed by VK3ER/P in/near the wombat state forest, and VK3BCU. No regular SOTA chasers, likely due to the hour and lack of alert. I could have qualified the summit in 30 seconds if I put the 2m rubber ducky on the 817, but I would have been there for another half an hour working the hordes… the weather was pretty miserable with a freezing southerly wind.

Not successfully qualified, but 3 more 23cm contacts, summit activated, and an Andrew 2 Andrew. What’s not to like? Longest was 113km with VK3ER/P.

Only 15 minutes or so late for the meeting.

New Years Rollover

The lucky SOTA addicts in VK (and now ZL and JA) have UTC rollover during a reasonable time period:  11am EAST. This means double activator points can be claimed so many have headed to the hills on the 1st of Jan, and usually to high value summits. Thus far I had managed to miss all this fun.

With a couple of days in Albany, a 50 minute drive south of the Stirling Ranges in WA, I had the chance to finally take part. The only catch was that rollover is at 8am in VK6. 

Having chosen Toolbrunup Peak VK6/SW-004 and working the numbers back, I figured an 5am start would see me on the summit safely in time to qualify both sides of rollover. I last climbed this one 18 years prior with a group of University friends. It’s a 2km climb to the summit.
An uneventful drive after 4 hours of sleep saw me arriving at a packed! car park. One couple had camped overnight on the saddle and had just walked down, several other groups were heading up.

A quick  breakfast at the car and I was off. Don’t be fooled by the easy section here, which I might add I fell on during the descent… 

Through the scree field: 
With nice views poking through (not the summit): 
  and then you get to this:

 You’re rocking hopping and climbing the rest of the way to the summit. Almost no one I saw climbing, including myself, had boots. I used my trail runners which offer excellent grip but no ankle support and others used even lighter running shoes. Provided you have strong ankles and good proprioception a light shoe is not necessarily a bad choice here. 

The second boulder field with a trail marker:  
  
 One exiting the boulder field the path veers to the right through thick squipole unfriendly scrub to emerge at the base of the final climb.  
 The path is marked but not particularly well. Last time we deliberately chose a route further to the right which offered a nice section of climbing. The normal path however offers enough fun, especially with heavy pack:

None of it is particularly exposed however.

And finally up the top which as I remembered is a jumble of giant boulders:

  A leisurely setup allowing me to catch my breath and I was on air at 7:36am, my spotted time, having burnt all my 30minutes margin on the climb. The rocks did offer the best shack I have ever operated from (which was on the western side of the summit):

  
As i was about to check 14.310 I found John VK6NU on Mt Randell doing the same enabling a quick S2S to get the ball rolling. 5 minutes later I had qualified the summit, I think a record time for me in VK6 including S2S’s with Matt VK1MA on VK1/AC-008, Andrew VK1AD on VK1/AC-043, Gerard VK2IO on VK2/HU-093 and initiated a S2S with JS1UEH/1 on CW which crossed the UTC boundary. I believe the reports were exchanged in 2016 and have logged it as such. My first JA chase and S2S.

In 2017 I also worked Glenn VK3YY and John VK2YW on CW, reworks of the other S2S’s and picked up Phil VK6QS ON nearby Mount Hassell VK6/SW-009, Peter VK3ZPF on VK3/VC-005, Allen VK3ARH on VK3/VS-027, Tony VK3CAT on VK3/VC-037 and Andrew VK3ARR on Mt Buller VK3/VE-008.

There were a bunch of other chasers including Tom VK5EE, Nev VK5WG and Rick VK4RF.

Phil VK6QS was on my backup summit, within 2km LOS and we both managed to clobber each other. I eventually gave up with a s7 noise floor (the phase noise of the 817 LO?) when both in the SSB segment, and let him work the chasers.

Trying 15m CW, I had a call from steve VK7CW with good signals but he couldn’t hear me, and almost completed a QSO with JJ1SWI which would have completed JA for me but he faded before I got my report.

In general weak signals, and many I couldn’t hear. Tony Vk3CAT was an easy copy on CW, but not a trace on SSB. Good signals as always into VK5. All completed QSO’s were on 20m at 50W.

I did try 40m SSB but couldn’t find and hold a frequency due to DX QRM.  

Plenty of reptile life on the summit with a whole family of lizzards coming out to sunbath, including right where I was sitting. I’ll have to dig out a photo from the SLR.

Name that SOTA peak, several in there…

 
During the descent I did fall on an easier section of track landing heavily on my right wrist trying to arrest my further slide. It became rather swollen and bruised and I ended up having to drive out one handed. A week later and I’ve got most of the use back. It just shows that you can’t relax for a second on most of this track. Ankles were also fairly tired from the walking on uneven/unstable surfaces. I’m a bit out of shape…
 

Not bad day out despite the early start. I even got to practice some rusty Deutsch with no fewer than 5 of the others being German! 

Frustratingly I ended up on 995 chaser points…  would have been the perfect summit to reach Shacksloth on!

UPDATE:

Family of lizards. 4 in the first image, found two more in the uncropped image. Saw probably a dozen in total.  

  

Squid pole bag

I spent 2 hours on my sisters sewing machine to make a bag for the 7m squid pole that will be more flexible in mounting arrangements on backpacks, especially my 30L day pack. None of the squid pole bags seem to ever have loops.

Designed also to allow the pole to sit below the pack a bit.   

Made from 210D nylon (same as the pack I believe), webbing and fixtures from Tiergear. My sewing skills after almost 30 years leave something to be desired, but as a first effort/prototype it will do. Still need to trim threads etc.

Leg clearance is almost right, probably should put the pole slightly higher.

 

The edging was a major pain, couldn’t easily pin it with what I had on hand so it got out of place a few times! 
Now to see if it’s strong enough. I suspect it will outlive the pole. At least the top cap for the pole will stop falling out.

Now to build one for the short & light travel pole, which will work with ice axe loops on many packs
