No.Don't most TV stations have multiple antenna locations?

Actually TV stations do have multiple translators to augment their signals in areas shown to have poor reception after the digital transition.

So there are two different repeaters used by television, often in more rural areas.
Translators, which repeat the station on a *different* channel. These were all required to go digital or go dark at the end of June.
Translator networks are big out west, where the tall mountains and distance between cities can cause issues. (Now, some of these translators, if far enough away, can be on the main channel, but that's extremley rare)
On Channel Boosters, known in our industry as "SFN"(Single Frequency Networks) are becoming more and more common. This is where a TV station uses multiple transmitter locations to improve the coverage in favorable parts of the market where the primary signal isn't seen with good quality. WEDW-TV , the PBS station in Stamford, CT, is running a 3 site SFN. One on their original (Hi-Ho) tower, and two with different patterns in New York City. The modern transmitter exciters can be setup to all be GPS frequency locked and set so the carriers are delayed to be "in time" with the signal as well, so a person could see both signals and not ever know it. And these are full power duplicates of the main signal, they are not restricted in power like translators are.
So the correct answer is "yes" .
Now to the OPs question. Channel 7.
In North Carolina, there are three, ATSC (not analog, no analog audio either) translators
WHFL-CD (Technically a class "A" signal)
W07DS-D and W07DT-D, both run by Hearst's WYFF-TV
In South Carolina
WOLO-TV is on channel 7, also in ATSC, and also with no analog audio.
I will contend, he's either hearing a rogue wireless mic, a spur off of a failing transmitter/station, or a pirate who has no idea what they are doing.
Not NYC or DC, both have ATSC channel 7 being used there.Not a wireless mic...both voices were equal clarity. On a wireless mic one of them would be "off mic."
I think its VHF skip...with the fade and total signal dropout. TV or radio station IFB transmitter somewhere. In NYC and DC, the stations use VHF IFB systems with the antennas at some elevation for good citywide coverage!
Analog skip is very possible, but until the OP says what he hears for any IDs , it's all just guessing now
and there was nothing besides a couple of NXDN systems (I appreciate your suggestion so now I'm going to follow those) so I'm not sure where else to go.Scan from 161-162, 450-451, and 455-456 and see if you hear the same audio.
Yes low power use, but if the antenna is high enuf it can have quite the range...we could get the CBS IFB all over DC when I worked up there...I'm not so sure the transmitters weren't more than the 50mw allowed today!Not NYC or DC, both have ATSC channel 7 being used there.
174 Mhz is only limited to low power IFB use only, anyways.
Analog skip is very possible, but until the OP says what he hears for any IDs , it's all just guessing now
I can see if my brother in law has timeDo you know anyone who speaks Spanish? Interpreting to English is gonna be your best be to getting to the bottom of this!!!
No it does not. There is nothing in rule 73.1201 that states the ID must be in English.yea a Spanish language station has to ID in English!!!
