[dorkbotdc-blabber] AFSK tone generator

[Rob Carlson]

I'm trying to send NWS SAME messages to a weather radio rechipped for a 
two meter ham frequency.

via Wikipedia:

The system transmits digital tones over normal audio using AFSK, with a 
2083.3 Hz mark tone and 1562.5 Hz space tone, lasting 1920 μs (1.92 ms) 
each. The data is encoded in 7-bit ASCII but uses all 8 bits, with no 
parity bit and no stop bit ("8-N-0"), at a bitrate of 520.83 bits per 
second
