This just started a couple of weeks ago. I don't know what to make out of it. The frequencies I listen to have been long time standard for myself, so I know what I have a problem with and what I don't for the past almost FIFTY years. This is new.
Take note of the Details:
1. Between 156 & 162 MHz, usually the most important ones (to me), varies during the period of occurrence, (Railroad & Marine channels affected)
2. Two different radios (scanners) Realistic Pro2004 & a Regency HX-1000 (which I have yet to find a radio that comes anywhere close to the performance, interference (image) rejection specifically to this,
3. Early morning that seems to decrease mid morning (from around 7-8am to around 10-11am) then disappears completely.
4. No set days, example; happened a Sunday morning, but not the next Monday,
6. Comes across as broadband noise, rapid fluttering as someone has a button stuck in a fast moving vehicle. It remains fairly constant level (for the most part)
5. Breaks squelch, not strong, sometimes unable to 'squelch' out on the Regency due to a excellent squelch circuit.,
6. Both radios connected roof mount discones,
7. Same channels programed on both radios,
8. Usually on both radios the affected channels are the same, or close in frequency,
9. I have a FM trap and a custom notch trap for UHF on the 2004, nothing needed on the 1000).
My only guess based on the behavior is distant reception due to weather (short range skip or similar). As far as what is causing it, I have no guess, thanks to the FCC, there is so much CRAP out there, though one would think (hope) the high band would be least affected.
Ok, any guesses out there??
