close call 108.2083mhz

I'm wondering why i'm getting this frequency so strongly inside the lower level of my house (below street level), I don't hear any modulating but all the bars are lit up on the graph and it won't squelch away either.

FM Radio station near-by?

Cable TV leak?

 

[nautlynch]

Is cable TV at 108mhz? Maybe it's a neighbors FM MP3 transmitter for the car but it would have to be modified for that much distance.

My guess is that it is really a harmonic you are hearing from some other device, which means it might not necessarily be a radio transmitter. Check some of these and see if you hear it there as well:

55.04
72.139
162.312
216.4165
324.625

Cable TV can be ANYWHERE, I get interference from their leaks on everything from low band to UHF-T.

HRC Cable channel 98 108.0054Mhz

This is the video carrier so you probably wouldn't hear anything if indeed you are receiving it from your cable system.

Cable sometimes has used this freq range for leakage testing carriers. Ours had a weird sweeping tone all the time.

Good point. Leakage signals can be anywhere.

Another question for the OP, is there another receiver in the area? I had a satellite receiver that had a very strong signal on 146.76Mhz.

Check any connection points in your basement first...

Hey! That's my photo )

I use it on FB too.

I had a satellite dish down converter for Musak putting out a signal right on one of our rail transportation freqs last year. Some snooping is in order, find where the signal is the strongest , then take the antenna off. Should be able to narrow it down pretty good that way.

Any luck yet?

Try shutting off all the power to the house and run the [hope it's a portable] scanner on the battery, see if it's still there.

If not then, one room/breaker at a time restore power and see which room
restores the interference.
