23cm on 23rd #2 – 23 March 2019

Saturday 23 March 2019. I have organised a VK1 SOTA ’23 on 23′ event where SOTA tragics, that’s like minded SOTA activators, have the opportunity to join others for a local Summit to Summit (S2S) fest on 23cm 1296 MHz, SSB, CW and FM modes.

Today’s SOTA activators include:

  • Compton VK2HRX/P at Mt Gibraltar 163 km north-east
  • Jim VK1AT/2 at Mt Cowangerong 43 km east
  • Andrew VK1DA/P at Mt Mundoonen – 70 km north
  • Al VK1RX/2 at Spring Range – 40 km north
  • Bill VK1MCW at Mt Stromlo – 17 km north
  • Chris VK1CT at Mt Majura – 24 km north-east

Our local VK1 23cm enthusiastic chaser group is just as impressive which includes: Rob VK1KW, Jason VK1JA, Ian VK1BG, Matt VK1MT, Chris VK1DO/VK2DO, Rod VK2TWR, Dale VK1DSH and the occasional contact with Dimitris VK2COW. In Sydney 276 km north-east Mike VK2FLR and Compton VK2HRX take an interest in the hunt for 23cm signals emanating from VK1.

Today my plan is to activate Tuggeranong Hill VK1/AC-038, 855m ASL in grid square QF44NN. I left home at 6:30 am, yep it’s dark outside, for a 20 minute drive to Callister Crescent, Theodore at the base of Tuggeranong Hill. From the car park the walk to the summit takes 30 to 35 minutes to cover 1.5 km along a fairly steep gravel fire trail. See below screen shots.

23cm equipment:

To drive a 23cm transverter one needs an IF source, conveniently SG-Lab’s 23cm transverter is designed to operate with a 144 MHz IF input between 0.5 to 5 watts all mode. What is the most common portable QRP SOTA rig around and ideal to work as a low power IF on 2m and 70cm, yep the Yaesu FT817! The rear SO239 antenna port is driving the 2m yagi while the front BNC port is driving the 23cm transverter.

You can of course drive the 23cm transverter with a 2m HT operating on FM, as I did last month from the summit of Mt Taylor.
