SOTA VK Mass Activation – One Tree Hill

One Tree Hill VK1/AC-035 865 metres ASL – Australia’s Capital Territory

It’s Saturday evening and VK SOTA activators have taken up positions on summits in the south-east states of Australia for a chance to work SOTA enthusiasts in the northern hemisphere and local summit to summit activity.  Some activators are so keen they have taken up positions one or two hours early and are camping overnight. VK associations participating are VK1, VK3 and VK5.  Matt VK1DA is activating a VK2 summit, Spring Hill VK2/ST-036 near to the ACT/NSW border.

I plan to activate One Tree Hill a border (ACT/NSW or VK1/VK2) summit located 5 km north of the township of Hall.  Access is via the Canberra Centenary Trail which is designed to be shared by walkers and cyclists.  The track is roughly 5 km and takes 40 to 50 minutes walking to reach the summit.  Activating late in the afternoon will mean walking back to the car in the dark!  One aspect of this walk which I didn’t enjoy was the bloody flies, annoying little critters. Being cattle country the are gazillions of opportunistic flies buzzing and circling your head, face, ears and arms anywhere where they can land, I hate flies they really do take the enjoyment out of a good walk.   If you are planning to walk this track my best advice is to lather yourself in insect repellant before leaving the car, you might stand a chance against the marauding flies.

My plan for the evening was to arrive at 17:30 local 0630 UTC and set up 2 radios FT857D and FT817ND with separate antennas.  Why two radios?  I wanted to try the 817 at making one or two DX contacts with a lightweight end fed antenna, unfortunately at 09:40 UTC a foreign power taking advantage of excellent propagation flicked the switch on an over the horizon radar which blew any prospect of QRP DX out of the water. The radar signal was S9 and easily 150 KHz wide, I moved from 14.320 down to 14.175 MHz to escape the bulk of the noise each time I moved the signal seemed to follow me around.  The guys in the UK were hit by it!  I moved up to 14.340 where Al VK1RX was operating just on the edge of the noise. The pulse signal was still sufficiently strong to degrade a DX signal to background noise. 😦  Not being able to compete with the radar I packed up for the 5 km walk back to the car.

Started the activation at 06:50 UTC and concluded at 09:40 UTC in the dark. 2 hours and 50 minutes.  I did get to operate the FT817 on the lightweight EFHW  for the first 10 minutes working local VK chaser stations on 7MHz, making S2S contacts with Allen VK3HRA on Mt Buller,  Rik VK3EQ on Andrew Hill and Nick VK3ANL visiting Canberra activating Black Mountain.

The bulk of the activity was on the FT857D running 40 to 50 watts output into the ‘link’ dipole.

Countries worked; England, Finland, Germany, Slovakia, Italy, Sweden, Switzerland*, Hungary, Holland*, Spain* and America*.   On this occasion new counties are marked.  States worked in the U.S. were North Carolina, South Carolina and New York.

DX summit to summit (S2S) contacts were with Lutz DL3SBA/P on DM/NW-226 and Stephan DM1LE/P on DL/BE-003.

Woke this morning with a three bite marks on my right leg, either from spiders or other creepy crawly bugs. 🙂

One thought on “SOTA VK Mass Activation – One Tree Hill

  1. Hi Andrew,
    The OTH radar was really strong last night. I had just called Lutz DL3SBA/p (DM/NW-226) when the radar kicked in (5/9 plus). It was across the majority of the 20m band, as low down as 14.175. Fortunately it disappeared after 20 minutes and I went back to work Lutz, who was luckily still on the summit.
    Well done on the activation.
    Best 73,
