SOTA – Devils Peak Brindabella National Park

Saturday 3 December 2016.  It’s a warm summer day in Australia’s Capital Territory Canberra with a top of 30 degrees C, a perfect day to tackle two summits in the Brindabella Ranges 30 km west of Canberra.  At higher altitudes the ambient temperature will be 5 to 7 degrees cooler.   My aim for today is to activate Devils Peak VK2/ST-004 followed by Dingi Dingi Ridge VK2/ST-004.  My last activation of Devils Peak in May 2014 with Ian VK1DI turned out to be an adventure we both didn’t expect.   Having learnt not to venture into a large swamp, today I am taking a direct route to the summit, 300 metres south-east of the swamp following a spur line heading south-west.

From my QTH in Canberra the drive to Two Sticks Fire Trail is about 1 hour taking Brindabella Road followed by Blue Range Fire Trail.

Start of the walk – leaving Two Sticks Fire Trail heading south in to the eucalypt forest.  There are no formed walking trails, this is an Aussie scrub bash to the summit of Devils Peak.   What do we do to ensure the safety of activators in terrain like this?  First wear clothing to match the environment, make sure you have ample water, food and some form of emergency shelter.   I wear ankle high boots and gaiters, I have a first aid kit on hand, two litres of water, a high vis yellow emergency shelter plus food for the day.   In the top section of my backpack is an emergency signalling mirror (heliograph).   In an environment like this it’s important to have an emergency communications plan.  In VK1, local SOTA activators/chasers often volunteer to monitor the progress of fellow activators en route to summits in difficult or dangerous terrain.  Not to make a big deal out if it, this environment is known for snakes.  I am not afraid of snakes, however 300 metres to the west of my planned route is a saddle formed as a swamp teaming with frogs!  Snakes love a diet of frogs.  Whether or not the terrain or fauna presents potential risks, having a communications plan is an important aspect of safe bush walking anywhere in Australia.  On this occasion Al VK1RX offered to monitor my progress via Mt Ginini 2m repeater VK1RGI on 146.950 MHz.  I checked in with Al when departing from my car then each half hour, on arrival at the summit, departing the summit and later on returning to the car.  Accidents can happen while driving along narrow 4WD trails and walking or hiking in the Australian scrub, its good to know your mates and friends are looking out for you.  πŸ™‚

400 metres to go the terrain is now quite steep and the scrub is getting heavier. Difficult to see 50 metres ahead

400 metres to go – the terrain is now quite steep and the scrub is getting thicker and wet.  Difficult to see 50 metres ahead, I pause each 10 to 20 metres to plot a route of least resistance.

thick scrub, very pleased to be in a cool climate.

Although the scrub is thick scrub and difficult to navigate through, it’s nice to be in a cool environment.  πŸ™‚

On the summit 1 hour after leaving the car, sorry folks no views to be found just thick Aussie scrub.  Cloud has evaporated, it’s rather warm in the direct sunlight, shade is important!  My presence has come to the attention of Australia’s most annoying blood sucking insect, I’m being bitten by hundreds of mosquitoes. I had one bite me on the ear, others were biting through my trousers.  If Andrew VK1DA was here now his comment would be something like “there are so many mozzies they need a flight plan and final approach approval to land”   πŸ˜‰

After pushing my way through the scrub I found a small clearing to deploy a 40m 1/2 wave Inverted V dipole. The blood sucking mosquitoes are waiting patiently on the underside of the small fern leaves. 😦

6m contacts included Al VK1RX, Matt VK1MA, Andrew VK2UH and Rhett VK3WE over 302 km.  That’s the summit qualified on 6m!

Sporadic E on 20m gave rise to 15 chaser QSOs within 400 km out to 3100 km.  DX chasers on 20m included John ZL1BYZ and Warren ZL2AJ.

  1. Another excellent post both radio and cartographically! It was also very good to read about the safety/backup plan you hold, with more and more people venturing out to activate this aspect can not be overemphasised.

  2. Great post, Andrew. Sounds like quite the adventure with many rapid contacts. Well done!

  3. Nice post with excellent pics, Andrew. I tried to work you but with only 5W available (FT-817 and endfed antenna) I didn’t expect you to hear me. I could only just hear you. Maybe next time …
