Homebrew 160 meter AM/CW transmitter receiver

The VK 160 and AM SOTA event (1st April 2017) provided the deadline pressure needed to complete this build. The rig is a separate transmitter and receiver, so seeing as there are no shared modules, I shall call it a trans-receiver rather than transceiver. The designs for both transmitter and receiver are by Drew Diamond VK3XU. See Drew’s Projects Volume 3  book for full details, available from the WIA or RSGB. I posted details of the 160m AM receiver when I first built it, a year ago. At that time I also built the transmitter and power supply. I got the transmitter going but blew up the PA FET (BUZ90). During the long wait for replacements, I shelved the build and moved onto something else. Now, thanks to SOTA, it is finished.

Return to Mt Gordon VK3/VN-027 and Mt Strickland VK3/VN-030

Sunday 10th July 2016 turned out to be my first SOTA outing for several months.  Weather was windy, overcast with intermittent showers forecast, not the worst of winter, so I headed up to the northern end of the Yarra Ranges. First up was Mt Gordon VK3/VN-027 on the way to Marysville, turning off opposite the trout farm, my second visit here (the first one was on June 8th 2015).  The summit was windy and cold. I set up the dipole which performs better than the vertical. Self-spotting and going on air at 1430, conditions were average at best, the spot bought out two stations who I could not complete QSOs with, Matt VK1MA and Geoff VK3SQ Both were weak signals and faded right out on second overs. Five QSOs followed quickly, VKs 3GGG, 5IS, 2IO, 5EE and 2PX with my signals varying between 3×5 and 5×7.

Mt Dom Dom (VK3/VN-017) and Mt Gordon (VK3/VN-027)

On this particular Sunday in early June 2015 I allowed myself to be sidetracked on the way to Mt Gordon and Mt Strickland at Dom Dom Saddle.  Driving through the Black Spur and arriving at the Saddle,  just seeing the sign was too much of a temptation.  I pulled over and did a quick search on the tablet for access to Mt Dom Dom.  It looked straightforward so in I went.  At the end of the Dom Dom Saddle picnic ground car park there are two tracks.  The one on the right is gated and leads to walking tracks to Mt Boobyalla and Mt Donna Buang.  The one on the left is Dom Dom Rd.
