All true ... however, not all those modes are apparent to the
listener. Back in the early oughties, I always wondered what those
funny spikes were in the MMTTY spectrum display. Not quite evenly
spaced but close enough. I assumed they were just some form of RFI
while I was playing RTTY.
How was I to know they were PSK31?
I suspect that it's even worse with K1JT's growing suite - it is said
that the software can decode signals that are completely inaudible.
And yes, this has a bearing on the RM-11708 ...
