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.


"Upping HD Radio signal strengths"

"The short math given what we know today is that it will cost roughly
double on the transmission end to increase HD Radio FM power tenfold.
There are likely to be additional costs for cooling and air handling
as well, in order to dissipate the excess energy required to get out
another 10 dB in HD Radio signal. And, for some higher powered
stations, existing HD Radio configurations may not be able to handle
the power load, which could add to the cost and complexity of
increasing HD Radio beyond its current power level... Also worth
considering is existing transmitter combiner technology and whether or
not it can support the added demands of increasing HD Radio broadcasts
another 10 dB. If not, then it’s very likely that stations at the
higher power levels will need to factor in a new antenna system that
can support HD Radio, rather than piggyback onto their existing FM
antenna system. At the higher powers, especially, an immediate 10 dB
increase in HD Radio signal may be cost prohibitive... This will
typically mean the addition of another similarly rated transmitter
(using a combining technique) or the purchase of a new transmitter of
roughly twice today’s power level."
