Software Defined Radio Experiment with 10GHz microwave digital transmission over a highly-obstructed 120 km path with 500 metre hills. The receive path is via a remote WebSDR receiver.
The receive path from the webserver to my web browser feeds audio to the default Windows output, then Audacity takes that as a loopback input and echoes it to a Virtual Audio Cable and into a second instance of WSJT-X on the same machine.
This is all very silly, but it means I can do detailed path quality tests and other experiments in the middle of the night without needing someone else to operate a radio at the other side of the Pennine hills. Mow Cop WebSDR is a marvellous resource for this sort of experiment.
Normal machining service will be resumed in the next video, but this is a real use of some of the parts I've machined.
