Good evening, ladies and gentlemen.
While I was listening through the 20 MHz band tonight, I came across a digital mode I couldn't quite identify. It sounded almost, but not quite, like DTMF. It consisted of a few (8 to 12?) tones, of which one or two
were transmitted simulataneously. There were about four frequency shifts
each second.
I should have made a recording of it, but I was too busy fiddling with various digimode software (such as Stream and MixW) trying to get it to decode, and then it stopped.
Can any of you, on the basis of my description, make a guess on what it is that I have heard? Thanks in advance.
