I was playing about making audio cables to connect my cheap Baofeng to my PC. To test the recieve cable, I took a walk with the other Baofeng, and an Android App called SSTV Encoder.
To transmit, I held the phone up to the radio while I transmitted.
(yes, I copied the TX format image from MMSSTV to my phone before I left, just so I would have something with my callsign on to send.)
Obviously the second part of the test would be to tranmit from home to a remote station that I can monitor. Well that isn’t easy if you only hold an M7 Foundation license and you are working by yourself under the Covid-19 rules, so you have to muck about.
So, after setting up a recieving radio and phone in the girlfriend’s flat (support bubbled!) on the other side of the hill, using the Robot36 app (phone sitting next to radio with no physical connection)….
I am happy.
