I turned on my car stereo a few minutes ago and was about to turn on my sirius radio which I have the FM transmitter on 99.5 (it's a pretty good open channel for that kind of thing when pirate WNFR isn't on, and even when they are in most areas I travel). I was picking up a carrier with no audio on it. I know it wasn't WNFR as they don't come in at the location I was at. Does anyone know what this is or where it's coming from? I verifyed it with 3 different radios all with the strongest signal at 99.4.

There was a tropo DX opening last night, so it could have been WNFR on the wrong frequency.<P ID="signature">______________

Nope, tropo wouldn't affect WNFR as it's about 25 miles from here (think Lake Compounce area) and I was getting it again yesterday morning (didn't remember to check this morning)

I have no idea why this got deleted the first time I posted it, but -
Were there any radios nearby tuned to 88.7?
(That's not an off-the-wall question - almost all FM radios operate with an "intermediate frequency," or "IF," of 10.7 MHz. And almost all emit at least a very weak signal at frequencies 10.7 MHz above and below the frequency to which they're tuned. So a radio tuned to 88.7 will emit what sounds like a dead carrier at 88.7+10.7, which is 99.4. This is why there are spacing restrictions in the FCC rules for stations 10.6 and 10.8 MHz distant from each other, and it's one big reason the use of FM receivers isn't permitted on airliners, since the aviation band starts at 108 MHz and an FM radio tuned to anything above 97.3 can put out a carrier in that band.)<P ID="signature">______________

None, reception of WNHU is pretty weak here, I only get it clearly in the car, and that's 4 floors down, BTW: this is in the north end of Middletown.

25 miles? of course tropo would affect it!
I've picked up some really good tropo that wiped out locals with a lot more power than WNFR, while I was much closer to the transmitter site.
I'll give you an example. I was in Agawam, MA. picking up WPOC 93.1 out of Baltimore MD. Clear and in stereo. Mind you I was probably, oh, 7 miles from the WHYN-FM 8.9kW transmitter. I called the chief who indicated he's been getting a lot of calls, but the transmitter was in fact at full power.
So it can happen.
By the way, why are you talking about a Sandusky, MI radio station anyways?

Heh, I'm not, though when I first heard the call, I looked it up and got the MI station as a result. I might have the distance figured wrong, any idea how far it is from the Cromwell/Middletown line at route 3 to the southington/bristol line at 84? that's about +/- 4 miles from the tracking I tried to do of the WNFR pirate (and guys, if you're reading this, don't worry, I don't track to report, just a curiousity thing, heck, I might have knocked on your door to visit, I did with WWIL in West Hartford once, and I really don't have that much free time)
