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.

False - 90% of IBOC power is dumped.

The insertion loss depends on the combiner system. In cases of FM, using
separate antennae, there is no insertion loss. It's still a small amount,
any way you look at it. Tower obstruction lighting or AC consumption is much
more.- Hide quoted text -

"Linearized transmitters capable of passing the HD-R signal are of
necessity inefficient, often in the 30-40% range.
As such they take more electricity to operate. More power is wasted in
heat and more cooling is required. It can thus
cost three times as much to operate a linearized transmitter than a
nonlinearized transmitter with the same
TPO... Additional up-front costs are incurred for the injector and
reject load as well as the transmission
line parts to connect everything together.. year times 15 years.
Include the cost of additional cooling using the same

From Crawford Broadcasting - debunked again, Eduardo! Eduardo - is
your little research staff still laughing about HD Radio, Mr.
Chapter-11? LOL!
