RE: [digitalradio] Re: Humans as Busy Detectors
My QSOs fall into three categories: 1. chasing DX I need in CW, RTTY, and phone 2. running CW at the low end of whatever band is open 3. ragchewing in PSK31 or PSK63 I didn't count DX cops and their associated QRM in my statistics. The only time I remember substantially more frequent QRM was at the peak of the mid-nineties solar cycle on 10m; I worked more phone than CW back then, and wasn't doing RTTY at all. 73, Dave, AA6YQ -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Peter G.

I get QRM'ed every week at least once. I'll be in QSO with a station and WHAM! Somebody starts to call CQ on top of us. Or just off to the side, overlapping our QSO slightly. Or, I'll be attempting to tune-in a weak DX station that's either CQ'ing or in QSO and somebody will start to CQ right over the DX (THIS happens most frequently of all). I'm not saying any of this is INTENTIONAL QRM... but it sure is a common occurrence for me, de Peter K1PGV

Bonnie, do you mean 27.185 mHz?

Just try to hold a simple voice, CW, image, messaging, or texting QSO on one of the more active ham bands on any weekend will prove this fact to you beyond any doubt. Bonnie KQ6XA
