Raspberry Pi4 running Quisk and WSJT-X connected over the network to my Hermes-Lite 2 as a WSPR transmitter and receiver. I use VNC viewer to connect to the R-Pi remotely as it's running headless.
Quisk is really useful as it creates a pair of 'virtual audio cables' for digital modes making it very easy to link to WSJT-X as audio is otherwise a nightmare in Linux.
I've left it running 24/7 for a couple of days.
Can only get the power down to 0.5W on the HL2 but have also connected the R-Pi to my Radioberry and with no PA connected it only produces ~10mW, but still getting spots on every continent.
Antenna is a 1/4 wave vertical for 40m used for 15m as well. I guess the antenna works quite well.
Amazing what you can do on the 'grey line' - the difference is night and day!
