AFSK 1200 ax25 - first quasi light


Hello everyone, I have just finished drafting a working version of AX25
packet generator and AFSK modulator (baseband for the time being). The
ax25 related code is contained in the file, that is far from
nicely written.

I have tested the resulting audiofile with mixw on windoze and it
ok; tests on the air with the usrp will be prabably run in the we.

Best documentation with code examples I have ever found on 1200 AFSK is

thanks to W2FS and TAPR/ARRL
