I took out my HT and a

tuned the HT to 145.25 (the video carrier for cable channel

was pointed at the cable hardware on the pole. I tried 149.75
(the aural carrier)and also heard loud demodulated audio.
I think you may have found the cable TV's leakage problem. You should
send them a bill for consulting services at the same time that you tell
them you are going to call the FCC if they don't fix it IMMEDIATELY.
Leakage problems couple RF both ways, both out of their system and into
their system. You might additionally motivate them to fix it by parking
next to that leaky cable with the highest power ham rig you can find and
call CQ a lot. :)
