Sholto,

Thank you for the update, I did not realize MultiPSK had that capability.

 Ron  John,

 MultiPSK has an analyzer function in it. It can measure baud rate and 
 shift of RTTY  FSK signals. It will also attempt to measure the symbol 
 rate of BPSK signals.

 I'm guessing that at 14097 it was either a Packet or Pactor station.
 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. Currently I know of only Hoka Code 300 and the 
 Wavecom decoders which will even attempt it. Prices range from around 
 $8000 and up!

 Outside the ham bands there is little that can be successfully decoded 
 these days. These include Weather FAX, Aviation/WX RTTY (very little 
 nowadays), SITOR (again not much these days), HFDL, GMDSS DSC, Stanag 
 4285 (usually only test tapes), occasional ARQ-E stations, ALE, CW (eg 
 Cuban spooks) but also some Far Eastern maritime stations still use CW.

 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.

 MultiPSK can be downloaded for free at http://f6cte.free.fr/

 John,

 It is the PK232, I do think that there is that type of software out 
 there, wish there was.

 This question has likely been asked previously but I can't find it in
 the archives if it has. Is there any multi-mode software that will 
 attempt to automatically decode a selected signal? The reason I ask is
 there was something on 14097 last night and I tried muultipsk/mixw and
 the various modes available on them to attempt a decode but was
 unsuccessful. I'm not sure which TNC had it -- MFJ1728 or the PK232MBX
 but I remember using the SIAM mode to attempt to decode various modes
 that were available in the early 90's.

 Thanks in advance

 John
