Yesterday I hooked up a USB gaming headset to my Mac. The audio from my voice made it into the radio and I actually talked to another amateur radio operator over the air! And I did not hear my voice coming back at me through the headphones, so there is no chance of feedback. This all works. Thanks so much for the help. I will be writing a set of tech notes for the amateur radio community on how to integrate a Raspberry Pi, NoMachine, and a transceiver. When I have this done, maybe in a few weeks, I’ll submit it to NoMachine for review to make sure I am using your product correctly.
I took my iPad to a local coffee shop today and connected to my station through their wi-fi network. I made high frequency contacts with Germany and Belgium using a digital mode named FT8. Lots of radio fun. I was able to hear the audio received from my station clearly on my iPad. The day before I took my iPad to a Starbucks and made a Morse Code contact.
