Used to see this all the time in the old days. Probably using AFSK and either
over driving his transmitter or had his speech
processor turned on.

Subject: [RTTY] Odd RTTY signal, 3 pair of tones w/ 3 diff shifts
A strange thing happened in the Tara Grid Dip contest. I was tuning down in
frequency when I came across a signal that was 350 Hz
shift. I set my shift to 350 Hz and could copy him fine. Later I came across
a shift that was 240 Hz and the signal was reversed.
A little further down the band I found 6F75A transmitting with a normal signal
calling CQ. I opened up my bandwidth and could see 3
pairs of RTTY tones with 3 different shift. You could see all 3 signals in
sync as 6F75A transmitted. Anyone ever see anything
like this before?
