Jeff, Found it. Look here: http://mmhamsoft.amateur-radio.ca/ It was the MMSTV software that auto-decodes the SSTV signal. By auto- decode, I mean it determines the proper protocol for you (Scotty 1, etc.)
73, Paul I've spent hours runnng MultiPSK trying to figure out which variation of SSTV a signal is only to be rewarded with nothing. I've pretty much given up on SSTV for that reason. I keep plugging away at the rest of the digimodes, because I occasionally have success at decoding some exotic signal. And the real reward is finding someone in a QSO that wants to try other modes! > > Jeff -- KE7ACY > CN94
