Anyone know mode/protocol? (seems to be some sort of MFSK with
sync headers?)



3.5835 MHz is in the 80m ham band.
They have a couple MFSK modes.
Your recording sounds different though.
What mode was your radio in, USB? AM?


Sorry, forgot to mention CW, 2kHz filter. I have a collection of
digital mode audio samples but nothing quite matches; I'd like to
add samples of esoteric modes like Hell*, THROB, OLIVIA, etc. but
would need to do it over the air since some of these involve FM,
PSK, SSB, etc. and can't be recorded directly from an encoder.
