I am picking up the sound from my cable TV channels. At first I thought it
was a local AM station but have since definitely identified one channel. I
am hearing the sound from cable channel 68 at 4.825 MHz.
I have a Butternut HFV-6 vertical and bring the coax into a B&W coax switch.
>From there I feed either a 75S-3 or a R-390 selected by the switch position.
By turning off the product detector and using a wide passband, I can hear
and somewhat understand the signal. With the product detector it just
sounds like a several KHz wide area of shot. I have a particularly annoying
one at about 14.196 MHz and there are others. Channel 68 is the only one I
have been able to positively identify. The sound is a little difficult to
understand and unless something is said that gives a good clue about the
channel, its hard to tell which one it is.
This all started about a month or so ago. This weekend is the first time I
started to look for it with the general coverage receiver. I do not have a
SW receiver to prowl around the neighborhood. Is this definitely a cable
company problem? If so, do I have enough information to contact them? If
not, what will it take to make a case?
