6925 USB
0512-0530z: Hearing what sounded like several versions of "Psycho Killer", including original Talking Heads version. Just barely audible through heavy local t-storm crashes and RFI.
Note regarding erratic propagation conditions: An AM carrier appeared around 6925.4 a few minutes after the 6925 USB station started with "Psycho Killer". But there was no deliberate QRM. I chatted with both ops via IRC and e-mail - both had checked the frequency and neither heard the other. DeltaCharlie, in NC, heard the AM station (http://www.frn.net/vines/Forum4/HTML/017562.html) while I heard only the USB station here in Texas. As far as I can tell, DeltaCharlie didn't hear the USB station. Neither did EvilElvis in Disgraceland, and he usually gets much better reception than I do. In terms of shortwave propagation theory, we're not that far apart, but are experiencing very different conditions in reality.
Just wanted to note this as an example of why folks shouldn't jump to erroneous conclusions about QRM and accuse other ops of deliberately interfering. With propagation conditions being so unpredictable now, it's almost always unintentional. And in this case, when the USB op saw DeltaCharlie's log for the AM station, he went QRT even tho' he'd been on frequency first by a few minutes.

got it. it is sort of concerning though.
