LMFAO! Expect the rest of he jammers and scammers to turn off IBOC -
they are all going under and can't even afford their electrical bills!

Hope it's true. What do you think Eduardo?

HD hardly uses any electrical. A sidelight on a tower uses more than
most.

Citadel turned of HD on a couple of AMs which were interfering at night,
WABC an WJR.

Eduardo -YDF - You can't have it both ways - Either the interference
is a significant problem on AM or it's not. How come WBZ or KDKA or
WHAM or WWVA keep their hd on full time? I'm within the protective
contour of KDKA and WBZ interferes with them at night.

To stations, the issue is not the protected contour but the groundwave
useful coverage area and the dimensions of the Arbitron metro. WHAM and WWVA
have no interference in their metros or areas immediately surrounding them.
Neither do KDKA and WBZ. But apparently, WJR and WABC had problems in areas
right at the edge of the metros, and decided it was not worth keeping the HD
on at night. Since night radio listening is only a tiny part of day
listening, the decision is relatively simple.
