Super cool concept. I was too slow

Like, hidden messages in songs / radio adverts / concerts that people can receive and decipher, it could be an ecash cheque but could be any information

I talked about other data over audio hacks on the first episode of

Bitpunk.fm

The zine, the poetry, the show: bitpunk.fm

. 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!

Neat that you gave it a try though.
