However, reading all these posts suggests that what these wonder modes want and or need is channelized, clear channel frequencies, with no human factor strengths added. Is that realistic to expect on the ham bands? 73 de Brian/K3KO I'm afraid that only PACTOR 2 or 3 has any chance of making it through these conditions OM. Everything else fails. Actually, I had Olivia and PSK QSOs through the RTTY QRM this weekend. By judicious use of the narrow filters and IF Shift/Width controls, I was quite able to work through even severe QRM, where RTTY stations would start transmitting nearly on top of us. de Roger W6VZV
