So I just get my PAR filter to take out the local TV channel 9 signal that has been overloading my scanner. Now that this is mostly taken care of, I have discovered a new problem...
My local cable company appears to have some leakage. I'm guessing it is their interference and not mine (i.e. not inside wiring causing the problem). On the cable TV channels from 14 through 22 that are in use on my cable system, there is significant intereference being presented to my scanners. I suspected this was the case when I first noticed it on my PRO-97 walking around the house. But, now I notice it on my PSR-500 (which is hooked to an outside antenna (a Ringo ARX-2B 144-148 mhz amateur radio ant) using LMR400. In large swaths all across the VHF band (air / public safety / etc) there are areas where I have multiple bars on the signal meter of interference (it's just like an unmodulated signal) - and of course at the center freq of the audio for each of those active channels i hear the actual audio (somewhat distorted since the scanner is FM and the audio is WFM).
I'm wondering if anybody else has ever encountered this problem, and if so what have you done to resolve it. Is the cable company required to remedy this problem (assuming it's leakage outside of my house)? I'm going to unplug the cable from the outside box and put a terminator on it and then listen - to see if i'm still seeing the problem after my house cable wiring is unhooked.
Just wondering if I just have teo live with it or if there shoudl be NO discernable signal external of their cabling. I've always understood that it is a closed system and that _any_ leakage that can be detected from a distance is something that the cable company is _obligated_ to fix.
So, anybody wanna bite on this question?
