"Are Elevated FM IBOC Levels a Good Fix?"

"Certainly the initiative, though not yet at the level of an official
FCC request, has its critics, who cite potential for increased
interference as well as increased implementation costs. One wrote on
an engineering listserv: The NAB has determined that they think the
increase to 10 percent will work without interference or damage to the
analog. They haven’t said they’re sure. How do you go to the FCC
without being able to document your claim? Another engineer said in an
interview that an FM power increase would result in a replay of the AM
[interference] problem.”

"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."

little pocket-radio,

D'OhGo ! - We Have Met the FCC and We Own Them !
-so says- Very B I G Corporate Media Ownership

The 'concept' behind small media ownership and limited
media markets was that no one media corpoation could
exercise control over all members of the US Congress :
Now with Very B I G Corporate Media Ownership a
company like Clear Channel Corp has Total Control
over the US Congress and thus : What Clear Channel
Corp Wants The FCC Does.

in reality the us congress sucks ~ RHF

G17,

That is why the 'logical step' from 1% of the Analog ERP
is 4% not 10% and Testing for Full Technical Compliance
to the FCC's Mandated FM HD-Radio Signal Mask that
the FCC imposed on such transmissions.
http://www.jampro.com/uploads/images...LHD/ALLHD1.jpg

One Year of Operation and Monitoring of HD-2 Channels
at 4% without Technical Violations or Public Complaints;
followed by a step-up to 10% with One Year {Year # 2}
of Operation and Monitoring of HD-2 Channels at 4%
without Technical Violations or Public Complaints.

During Year # 2 the Primary FM HD-Radio Signal could
be stepped-up-to 4% of the Analog ERP with One Year
of Operation and Monitoring of Primary FM HD-Radio
Signal without Technical Violations or Public Complaints.

Yes Indeed - Good Luck Raising the Power
in Full Technical Compliance [.]
