My first trip into #wspr Weak Signal Propagation Reporter.
After much head scratching, and no instructions from a cheap AliExpress unit, I'm getting picked up on 20m band, 16000km away in Melbourne!
Found great repo on GitHub, flashed fw, up and running

Now the new fan #dipole is finally finished. Spacers made from cable ties. Lightweight. Works at 40m, 20m, and 15m. I'm excited. vy73

Yesterday I activated Mt Disappointment, VK3/VC-014 with the aim to test a #QMX on #SSB. The wx was cool & windy with a storm sweeping in from the N-W. #Antenna - link #dipole, power - 4S LiFePO4 battery via 12V reg. Only QRV on #40m SSB and made 8 contacts from the eastern states...
For my amateur radio friends - here's a quick video I did of my new 240' doublet antenna using a remote antenna tuner at the ladder line feed point (ATU4K tuner from trueladderline.com).

I visited Mt #Buller (VK3/VE-008) in Victoria's High Country today for a #SOTA activation. A #solar_storm made the going tough, but two S2S contacts and two VK3s got me there. #Dipole antenna and 8W #SSB radio were set up below the summit to avoid interfering with the fire watch tower. #AmateurRadio
