I've been back in the hobby for one year after 10+ years QRT. I operate mostly CW, and I enjoy chasing states and DX on new bands. It is my perception that behavior is worse than it was "back in the day" and has actually gotten worse during the time I've been back on the air. For example, I got into the V84SAA pileup on 40m this morning. My modus operandi is to listen for the guy the DX op is working and jump in at that frequency or jump in at the frequency where I think the DX op will be on the next exchange. To accomplish this, I need to be able to hear the guy the DX op is working. That's really difficult if several folks are still sending their calls when the guy the DX op is working is trying to respond to the DX op. Also, people keep sending their calls while the DX op is sending, and they keep sending their calls when the DX op has responded to a specific call sign. For example, V84SAA responded a station with a "UA" prefix, clearly NOT a north American station. Among the fray, I copied the call signs of three north American stations, among others, who kept sending their calls, when V84SAA was clearly trying to respond to the "UA" station. To his credit, V84SAA stayed with the "UA" station until he completed the QSO. All I can gather from this is that the offending stations: a) can't really hear the DX op, b) aren't listening to the DX op, and/or c) just don't care and are rude, crude, and obnoxious. It is my perception that the DX ops could complete a lot more QSOs if they didn't have to put up with the cacophony of people continuously sending their calls and not listening. And finally, there is the tune-on-DX-frequency crowd. I use a non-resonant antenna and a tuner. Much more often than not, I can find a quiet spot not too far away from the DX frequency on which I can tune. Is it necessary to zero beat the DX frequency to tune your BelchFire 12000 QRM Plus amp? The behaviors described are not unique to the subject pileup. I see/hear it all the time, and it appears to getting worse. Yes, I finally got through and have V84SAA on 40m.
