RE: [RTTY] signal on 14.080?

[Jerry Pixton <jpixton@shentel.net>]

Scott, et al,

It is not MFSK16. I have a decoder for that which I sometimes use. You can 
hear the shifting tones in MFSK16 and see the tones moving around on the 
MMTTY display. I don't know what BPSK16 sounds like but one the MMTTY 
display it looks to have only several tones but the baud rate is much 
higher then rtty.

Interesting

Jerry,
