Re: [digitalradio] automatic signal identification
Sholto, Thank you for the update, I did not realize MultiPSK had that capability. 73 de Ron W4LDE Sholto Fisher wrote: Ron John, MultiPSK has an analyzer function in it.

Pactor comes in 3 varieties I, II III. MultiPSK will decode Pactor-I but for Pactor II III you need some very specialized and expensive software/hardware.

Interestingly the Cuban 'numbers stations' are experimenting right now with RDFT and also PSK220F which I believe is only available in MultiPSK Most RTTY stations you hear outside the ham bands are not RTTY at all. They often use a synchronous system and are encrypted so a normal RTTY decoder wouldn't make any sense of it. MultiPSK can also decode GMDSS DSC messages and VHF ACARS at present.
