Maybe one of your neighbors is using a baby monitor in a room with the TV on.

What I find interesting is that the old TV channel 1 was from 44 to 50 Mhz. The visual carrier was 45.25 Mhz and the aural carrier was 49.75 Mhz.

In 1945, channel 1 was 50-56 Mhz. In 1946 to 1948, it was 44-50 Mhz.
Am I in a time warp? That would expain the 4 second delay. Didn't they make a movie about this?

Someone must be putting the digital through an analog converter, then you are close, and it is mixing with something. (Unless 49.75 is the IF of the audio stage.)
Are you picking this up on more than one radio?

Since 49.75 is military, the nearby to him is Camp Grayling. They also are having multiple miltaries from all over and other countries. Im guessing radio peeps there were demoing their radios for their open house they had this past week?

I'm ~45 miles closer to the wjrt tv 12 transmitter then the OP, I just tried it on my 996P2 on an outside antenna, nothing.

I tried it from Fife Lake and got nothing. On occasion I'd get a blip of static but nothing I could decode. This certainly is interesting.

TV-12's studio is in Flint but its transmitter is near Montrose. How the signal is being converted from digital to analog, I don't know. I think krocus has the best theory. You may be near someone that is using one of those digital to analog converters to watch their old analog TV.

Transmitter is in Chesaning, along with wsmh, waqp
Other thought is someone was using 49.75, but happened to have TV12 on their TV so the radio mic picked up the audio?

It goes nonstop even when all the TVs are off. I will try mobile when I can.

Thanks for refreshing my memory. It is closer to Chesaning! But it is also a good 15 or 20 miles closer to the poster.

unless the transmitter is still analog, it does not matter.
digital and analog don't mix well.
for digital TV the sound is mixed in with the audio, it is not a separate thing anymore.

it is not a baby monitor frequency, i mentioned that before.
baby monitor/phone freqs: 49.67 .77 .83 .845 .86 .875 .89 .93 .97 .99 for the 49 range
i would agree but only with a plus or minus 5 khz
