Re: Input Needed for RadCom Column

Something like the sound of a pump key with a CO/PA two-valve
transmitter circa 1956 would do the job. Decent click, bit of
droop, gradual drift, good amount of chirp, and a few character
spacing and symbol length errors to add some idiosyncratic
"swing". Instant recognition of the "fist" without hearing more
than a couple of characters.
Is a CWID actually required at all under the beacon licence? The beacon could have a theme tune instead. Local folk song melody, or a nice short ID like the Radio Tirana ident from the 70s.
I'd certainly be keen to have a decent slow mode like JT4F/G or
PI4 which would work via rainscatter as well as weak troposcatter,
but also a fast mode like JT9F-fast that would work off aircraft,
and some plain carrier to look at the shape of the troposcatter
spectrum over 20s or so.
