I can receive TV sound in my FM radio (87-108 MHz) when the cable TV
transmission is in the VHF(Low) band, where the Audio is (Ch.Z)88.75,
(Ch:Z+1)95.75 & (CH:Z+2)102.75 MHz respectively. Though the audio
reception is clear enough, the VU meter of my FM radio hardly shows
any noticale signal strength. The FM radio is placed near the TV-set,
a few inches away. But the audio and video reception in the TV is
quite good. This leads me into a conclusion that a TV receiver works
at a lesser signal level. But I want to be sure about my conclusion.
That is the reason for posting this question.
