Anyone have a clue what could be causing a steady around the clock
one-second interval ON/OFF CARRIER on UHF? It seems strongest at
463.600 and comes in on NFM WFM and AM modes. It covers a good 2-3 mile
radius in a hilltop area, and seems no stronger at my house than 2
miles away. I can't seem to locate the source, it has many harmonics
and pops up all over UH. With a decent outside antenna, it interferes
with HF as well. Knocks the front end of scanners useless for UHF. Very
annoying. I live on a hilltop. Would it be a relay link of some sort?
