A6 negative offset, who is still analogue on East Coast?
« on: September 07, 2018, 0558 UTC »
Hi Guys,
for 2 months  i've recorded 87.75 with an SDR while beaming at North America (my qth is Northern England) looking for   transatlantic meteor scatter
this morning at 0543 utc i *MIGHT have had something on 87.74 (i'm trying not to get overexcited!)
so who is still on in analogue mode with decent power on A6- on the Eastern Seaboard of North America?

are all the "Frankenstein FMs" in the US on 87.75 zero offset or are some on 87.74?

thank in advance

yours  excitedly :D

Did you have a television image, or just audio?

If it was audio only.... The former television channel six frequency is 87.75 and it's often occupied by radio stations now. I have a Spanish language one here in Denver, KXDP (based in Boulder, actually). The rest of the traditional FM band 88-108 all have an odd number for the first decimal place (87.9, 88.1, 88.3 etc up to 107.9)

Here's a list of American radio stations transmitting on 87.75 MHz. If you got one, it would be an incredible catch because they all appear to be LPFM (low power - I don't know what the highest wattage a LPFM station can use, but the ones I've looked up don't ever seem to be over 100 W, or even as much as that.)

If it was TV, then it seems doubtful that it was American. I think all analogue transmissions have ceased, and Tim Bucknall's suggestion is a good one.
