A few weeks ago I noticed a wandering het on 1250khz USB.
Last night I found the mate to the 1250khz USB het on 1430khz LSB. Both were very active, changing pitch, sometimes rapidly, sometimes slowly. They are not continuous, either changing pitch until it drifts out of the receiver passband and then returning or fading away and then returning. My suspicion is that the source is a station half way between the two (180khz separation / 2 = 90Khz), 1250khz +90khz = 1340khz.: 1430khz - 90khz = 1340khz. Suspect a station on 1340khz is producing summetrical spurs approximately 90khz out from their carrier. Loop bearing for both wandering hets is the same, NW/SE from here. Both are heard only at night. My local on 1340 WJOL is almost at right angles and not the source. Similar activity was noted during the spring of 2013. But, back then I never heard the lower and upper on the same day as I have last night. Last year on different days one was noted near 1270khz and a few days later on 1430khz. Last night I could flip back and forth between 1250 and 1430 and hear them both. They are not noted every night, perhaps due to drifting right on channel or ceasing and disappearing completely. Anyone interested send me an e-mail and I'll send a brief clip of this odd sounding drifter. And, when you get a chance at night, especially if you are in the midwest, try for them on your rig.
