WFAN and WCBS Newsradio in HD-3

[DToTheJ]

@WGLI: I've heard Radio Disney bleeding in and out with 66 WFAN in Midtown Manhattan and I too thought it was WWJZ, but I stuck around for a TOH legal and sure enough, it was 1560 WQEW. Quite a blowtorch...

There's actually a good explanation for this. If your radio's intermediate frequency (IF) is 450 kHz (and most AM radios are), you can hear an image of a strong station +/- 900 kHz (2 x 450) away. I grew up with a signal on 1460 in my backyard, and it consistently wiped out 560 on most radios. (1460 - 900 = 560).

1560 - 900 = 660....

and, was it also received on your toaster, too?

The fading you hear in South Jersey is from WWJZ 640, the Radio Disney affiliate out of Mount Holly.   They're running HD and the sidebands interfere with WFAN.

Not anymore. WWJZ stopped transmitting HD some time last Fall -- and now NYC's own Disney affiliate, 1560 WQEW, has dropped it as well!

I found that happened by an OTA viewer in South Toms River with WABC-7. It was knocked out by nearby 92.7 WOBM because of IF. I suggested for an ABC affiliate, he would have to swing over to Philly for WPVI-6 until a solution would be found.

IF is one of those sneaky critters that will drive you nuts until you do the math.
