Struble - NPR 10db power increase for FM-HD will be a bust!
pocke...@gmail.com
"First, National Public Radio (through the CPB) has already
extensively studied this issue, more than anyone else in the industry,
and the results are pretty unequivocal that increasing the power of a
station's FM digital signal will adversely affect not only its own
analog host-signal, but also those of neighboring stations. So much
so, in fact, that the (first) study's coordinating engineer has
admitted in other fora that an increase in HD sideband power levels is
much more likely to do harm than good."

Bob, we know that Ford and your other 2010 automaker announcements
(cough, cough) are waiting on the reults of the 10 db power increase -
ain't going to happen, dude! Also, no one will be able to afford it:
"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."
When this is over, Bob, all you will have left is your KRI Armband
Portable HD Radio boat-anchor - what are you going to use as an
antenna - the headphones? LOL, dude!

When the NPR 10db Power Increase happens; then
KQED-FM 88.5 MHz will not only be in Stereo with
a Blinking Blue Light {almost HD}; will then have a
Solid Blue Light {Strong Digital Siginal} from SFBA
to Twain Harte, CA roughly 120 On-the-Air Miles.
bring on the fm hd-radio power increase
sounds like good news to me ~ RHF

Looks like you are an analog radio hater - the 10db isn't going to
happen.

While I don't 'think' HD-Radio makes sense
on the AM-MW Band.
I do 'think' that HD-Radio and HD2 Channels
make sense on the FM Radio Band.
AM & FM are Two Different Radio Bands with
Two Different Sets of Technical Parameters.
The Future of FM Radio is Two Fold :
* FM HD-Radio + HD2 Channels
* An Expanded FM HD-Radio Band {76~88 MHx}
PocketRadio it is 'you' who is the New Media Shill
and an AM-FM {Terrestrial} Radio Hater ~ RHF

You live in the boonies. FM IBOC takes up 3 analog channels. We don't
have that much space on the dial here in the big cities. The smaller
stations get wiped off the face of the dial.

They could never run IBOC here.. not on AM, not on FM. As I tune across my
car radio there are maybe 5 or 6 spots on the entire dial that do not have
first adjacent channels.

It would have to be fairly hard to find a pirate in amongst all of the
crowded band.. if it were broadcasting in Korean.. but an English language
station would tend to stick out like a sore thumb. (unless it were on 88.1,
88.3, 88.5 or 102.7, which are the AFN assignments).

Despite having been here nearly a decade now, I still know very little
Korean. I learned the alphabet very early on, and can read all the signs,
etc. (most of the signage here uses English, Spanish and French words
translated into Hangul characters, btw), but only know the most basic
touristy sort of stuff (how much does that cost, how are you, is anyone
here, etc., etc.).
I don't bother firing up the station, haven't in years, since the local AFN
affiliate moved on base (from their old spot on a hill a few Km from here)
and more or less destroyed any ability to hear the station on base, which of
course was the target audience. Before that, the signals were more or less
equal strength and neither could desense the other (they run a wholloping 40
watts EIRP from the top of the AM tower.. about 150' or so HAAT. I could run
35 watts at about 10' HBAT). I just run it online now. Totally legal that
way, and probably get more listeners (2 or 3, instead of none.. LOL)
