Driving home a couple of weeks ago, I noticed a strange het on 1040. Its pitch rose & fell very slowly (spanning a couple of musical notes over a minute), through roughly an octave either side of middle C (in other words, maybe a hundred Hz up to several hundred), with no apparent pattern, just a gradual rising and falling. Kinda like a very, very slow moaning. The aimless frequency drift reminds me of an old tube oscillator with poor voltage regulation and no temperature compensation! Listening over the past 2 weeks, I hear it all the time, weak during daytime and very strong during critical hours and at night. This might reflect that it has only a weak station to beat against during the day -- WZSK @ 100 miles distance -- versus strong stations to beat against during CH & at night -- WHO, WYSL (250 mis away) and WPBS (500 mis away). I hear it equally well from my home in Waynesburg, PA (40 mis S of Pittsburgh) to my dayjob in Morgantown, WV. At both locations, it direction-finds to roughly SE-NW. My Sony 7600 valiantly tried to sync the signal when I set it to 1041 kHz, which tells me that the station's frequency is always above 1040. My guess is an unhappy TIS, not too far away. I can't find a trusty TIS directory online -- anyone know of one? Is anyone else hearing this, esp DXers in PA, OH, MD, WV? Any ideas who/where it might be? Thanks.
