I talked about other data over audio hacks on the first episode of . The app I used was waver (ggwave). Psk31 makes sense for this ham radio application but waver is better for mobile to mobile. Lastly, a faster ham radio way to do this is to use the rattlegram app too.
This is super cool though :) I love seeing ham radio value transfer!
