Hi Dani,
   Thank you for your email. I have a USRP B200 and I want to use it to send APRS data using AX.25. I tried to use your example but somehow it does not seem to work. Is it ok if you can check what I did and tell me if this is correct or not?


   Thank you very much.

Hi all,

Maybe this example is useful:


It uses in-tree blocks and a couple blocks from gr-satellites to
implement an 1k2 AFSK AX.25 transceiver using the soundcard.

My suggestion would be to get familiar with developing your own blocks using gr-modtool. That particular project was all Python, so this would be a great place to learn if you don’t know already how to make A new module and add blocks to it.
