Most QRM in SStv or Digital SSTV is caused by contesters.. Most of whom are running splits and not listening to both freqs..The other is tuner-up-ers who do not know what a SSTV or Digital SSTV signal sounds like, so they just thing they are tuning up on a bunch of noise... The third is just plain QRM'ers who do it for lack of brains.. Trust me on this one,, we deal with it everyday on 7.173 Garrett / AA0OI

The fact is that most of the QRM is caused by people who call CQ in SSTV without receiving an ongoing QSO or a countrymen that is also CQ-ing (whom they don't hear). See Nils' (SM5EEP) article on "QRM Free Analogic SSTV" http://web.telia. com/~u22314111/ qrm.htm
