APRS is cool, but it’s also somewhat… complex. I wonder how hard it would be to write a “modem chat” phone app, with the ability to translate text into audible Bell beeps, slow enough to work without cables, to be used over ordinary voice frequencies.
- genewitch 5y agoThere are apps that decode via phone microphone, most of the stuff that fldigi and radios can do out of the box (for example, rtty) It works well, and is bi directional, you can key a transmitter and hold its microphone to your phone speaker and transmit valid "digital" modes. Works fine, especially over repeaters, which annoys the old folks and the lids alike.
