Does anyone know the source of periodic wideband buzzes that sound like this:
buzzz..buzzz..buzzz..buzzz (i.e. 4X then pause) buz..buz..buz (3X ~10 dB down). I believe this may be some sort of ionospheric sounder but I've heard this for decades, including when I was in Colorado. Hopefully someone knows what's generating this. 73, Bill W4ZV P.S. to K4PI re salt water. NEC models show approx +10 dB and very low angles for vertical polarization...no effect for horizontal. _________________ Topband Reflector Archives - http://www.contesting.com/_topband
