by high power transmitters that broadcast pager signals.
I used to have the same problem with (cable) channel 19,
which has a frequency range from 150-156 MHZ.
I realized that the interfering signal was originating from
Outside of the cable system. I purchased a scanner radio,
and searched between 150-156 MHz and found a
Extremely powerful pager signal broadcasting at 152.540 MHz.
The Cable Ch. 19 Video Carrier is at 151.250 MHz,
and the pattern of the interference matched the pager tones.
What are the frequencies for cable channel 68?
Are there any pager frequencies near Ch. 68?
