Weird situation

[gamefreak]

Just about an hour ago I was able to pick up 105.5 WDUV on the 99.5 frequency. Which usually has a weak signal from WQYK. In my area 105.5 pulls a decent 62DBu signal. What is the technical term for this.

That is strange; don't have an explanation for that; there is strong tropo (at least here on the bayfront/USF area of downtown St. Pete); all the Fort Myers and Naples stations are coming in like locals and speaking of WDUV, there is static and I can hear the 105.5 hip hop station on in Ft. Myers trying to come in on top of WDUV.

Is there a 99.5 translator somewhere that rebroadcasts a 105.5? We have a similar situation in Durham where a 105.5 translator, which feeds off of another translator at 98.5 is overridden by a full-power 98.5 in Rocky Mount.

Mo. WDUV has no repeaters. Even of Cox did it wouldn't be on 99.5. (Frequency of another Bay Area Station WQYK.)

If you are really close to the 105.5 signal and using a cheap radio, it is possible that you'll hear signals in weird places. I have a strong local on 106.7 and some cheaper radios place a ghost signal at around 100.6. But if you are far enough away or using a decent radio then it would be more of a mystery. And you say you have a station on 99.5. If its a translator it is possible that something went wrong and its relaying the wrong signal. If its not then I dont know what happened.

I was in Orlando last night, and the tropo was amazing. At various times, the Jacksonville and Fort Myers stations were fighting each other (WINK-FM and the Eagle were duking it out on 96.9). It was probably just a night of strong tropo.

Or you could have a neighbor who is using one of those cheap little FM transmitters to
rebroadcast them (I have one that I use to send webstreams of stations that don't come
in well where I live to radios throughout my house)

In Raleigh NC a couple of times a couple years back in the analog days on one tv, we used to get channel 50 on 35. Someone said there were spurious signals that would resonate from one frequency to another at those frequencies. It only happened a couple times. Maybe it's like that.

If you're not sure it was WDUV, it might be some kind of tropo. In the car tonight in Fayetteville NC, I heard La Rumba 100.3, which is usually WVBZ from 80 miles northwest or a station from the Outer Banks area. Never heard Orlando on there before, but I heard them identify it clear. Then again, there probably aren't many easy-listening stations to confuse it with.

Reception of channel 50 on 35 is an "image response", a well-known shortcoming of Maj. Armstrong's superheterodyne circuit. (used in all radios & TVs) Indeed, the FCC's analog regulations acknowledged that issue and prohibited use of two UHF channels in the same city if they differed by 15. (so when channel 50 was authorized in Raleigh, channel 35 went off-limits)

On FM the image response would be to a station 21.4MHz higher in dial position. Since the FM band is only 20MHz wide, you can't receive an image from another FM station. (you could potentially receive it from an aircraft station)

There are other possibilities for spurious reception though, especially if two different stations' signals mix.
