Hello All,
I have a question about a possible interference problem that I may soon be
experiencing.
I am considering a move from my current QTH to a new apartment. However, the
apartment I'm considering is located immediately next to three transmitting
towers. All three are commercial broadcast stations, one FM (102.7 MHz), one
TV (Channel 10) and one AM (1240 kHz). I am currently active on 2 m, 440 MHz,
and am very active on HF for shortwave listening and will soon be working
the HF ham bands. I am worried that moving so close to the towers will
cause problems with the performance of my equipment (noise, desensing, images,
intermod, etc.)
I plan to set up some dipoles very close to the tower sites and am worried that
it could ruin my enjoyment of the radio hobby if all the RF causes problems.
Has anybody had any experience with this??? Is it anything to worry about???
Any experiences anyone has had (or even just bold speculations from more
seasoned operators/listeners) would be greatly appreciated.
Thanks in advance,
Ron Synowicki, KG0HX

You haven't eliminated the RG-58 yet as the source of the problem. I have
hamfest special RG58 that nothing goes through at UHF. Do you know that
either of the lenghts of RG-58 is good? Do you have any known good cable
at UHF .
