Hi,
 
Thanks for the info.
 
I did not expect what you report. But thinking about it, I realized that the HD channels need to be added at the transmitter to the analog signal. So Mt. Diablo's KDFC-2 might very well not have the HD addition. 
 
I have a directional FM antenna (VHF 2-13) Yagi pointed at Sutro (and KDFC) in my attic (~ 1975) tied up with string.

The boosters often don’t have the HD carriers on them. I was in Dublin a couple a months ago and was wondering what happened to some of the HD stations. I power cycled the radio a couple of times before I realized I was picking up from the booster.  It turns out only the FM is on the booster, they do this to ensure there is no delay (analog link to the booster)

Hopefully this will change with time. For now to make sure you can get the KDFC HD2 use a directional FM antenna pointed to the main transmitter in the Marin headlands. I doubt the Mount Diablo booster has HD on it.

Hi,

That fool does not know about KDFC-FM on Mt. Diablo.

I checked Pleasanton and KDFC was on edge. So there is a need.

It has been many years since I drove up I680 but I do remember problems with KDFC.

Many of the Bay Area FM stations have translators.  Most are for covering Marin and north, or the areas east of the East Bay hills.  Go to http://www.fmfool.com and put in your address.  Like TVFool, you'll get a complete list of FM stations, signal strength at your address, distance and direction to each transmitter, and lots more information.  Callsigns with FM1, FM2 and FM3 are on frequency translators.

I never said that it would be otherwise, just that even with a good outdoor
antenna signal strength and therefore reception will vary.

That is a separate issue from urban/suburban reception problems where an outdoor
antenna is not feasible and the design of a good indoor antenna can make a
difference. 'Better living through better technology'

"Laws of Physics" have been subject to interpretation AND to new KNOWLEDGE over
the last century, at least. Examples are too numerous to list.

Point is, TECHNOLOGY CHANGES, just look at the variations in design of antennas
alone since 1920's. New products do come on the market - though not at the speed
one would wish.

We don't refuse to accept that fact. But it IS a fact that those people who are
out in the fringes and who don't erect an ideal outdoor antenna won't get OTA
reception, regardless of whether YOU accept that or not.

The laws of physics are inflexible. It's too bad you can't accept that.

Well it IS good to hear that someone else here is not too thrilled with the new
Sutro setup, and that I am not the only one noticing signal variations due to
atmospheric/weather conditions.

Some here still refuse to accept the fact that in the real human world, not
everyone is able to erect the ideal outdoor antenna, or is just out in the
fringes. If more people were more flexible in their thinking there might be less
friction and animosity in this world.... not holding my breath however.

As to repeater or whatever the appropriate term, I have always thought that
Black Mountain, down the peninsula back of Woodside where the original KPEN FM
transmitter was, would be a good place for repeaters to better cover the south
of Santa Clara valley. It is high and more inline with Sutro and Bruno from more
places.

Steven, you referred to KBCW as 45, it's physical channel, I was merely trying

The "new" Sutro has been a complete disappointment for
me here in Morgan Hill.  I use to reliably get ABC 7,
CBS 5, FOX 2, KOFY 20, KQED 9 and then other random
mixed language/format channels.

Now I get, only when cloudy and part of the time, MAYBE
5-1 and even less reliably 2-1.  I have been able to
tune in 20-1 occasionally.  I never expected to get 7
any longer when it went back to VHF and of course that
was the case.  I have never been able to even get a signal
for 9 and use to reliably get a 40-50 signal and my
tuner in both my DirecTV HR20 and Samsung Plasma will
tune in a signal all the way down to 30.

I have had an antennae since 2003 and always had some form
of reception and it was reliable.  Other than my VHF
antennae facing south for 8-1(NBC) and 35-1(FOX) my UHF
antennae is now useless. 

What I do get at or near 100% power is 36-1, 48-1, 14-1, etc. 
I wish all the studios had a satellite transmission
coming from Mt. Allison so that all of us in the south
bay had reliable, high quality off-air reception.

I cannot express how frustrated and disappointed I am in
the "new" Sutro.

Hi,

Sutro is done, the leaves are falling.

I am starting to get a picture of what my reception will be this winter.

KQED (30) reception has been spotty and gone completely some of the time in
the afternoons (~ 3 PM, NewsHour).

KBCW (45) was also gone Thursday but came back for the 49'ers game.

KDFC (FM 102.1), KDFC-HD2 is dropping out (Silence at times) this morning.

In the evenings and nights KQED and KBCW are OK as is KDFC-HD2.

So, there will be problems for me with an antenna in my attic this Winter
just like past years.

Rotating my UHF antenna may or may not help, it did not just before the
49'ers game when I was in a panic.

To answer Stephen's questions...

The last I heard all stations on Sutro Tower were operating on their permanent antennas at full authorized power except for KRON and KFSF.    KTVU was granted their power upgrade and is now operating at 1000 kW.

KRON is operating at 530 or 540 kW with Special Temporary Authority due to a conflict with their new antenna.  Apparently its radiation pattern doesn't match the information on the KRON application, so they have to get a change approved before they can go to 1000 kW.

There was a problem with the new KFSF antenna and the last I heard they were still operating on the auxiliary antenna.

Maybe Bob or Don can update us on these two stations.

As for KDFC, their transmitter on Mt. Diablo is a translator of the main transmitter.  With FM you automatically receive the signal that's the strongest, and if you're traveling, you don't even notice if you go from one to the other.  The only way to tell which signal you're getting at home is if you have a very directive FM antenna and can determine what direction you're getting the signal from.  

Many of the Bay Area FM stations have translators.  Most are for covering Marin and north, or the areas east of the East Bay hills.  Go to http://www.fmfool.com and put in your address.  Like TVFool, you'll get a complete list of FM stations, signal strength at your address, distance and direction to each transmitter, and lots more information.  Callsigns with FM1, FM2 and FM3 are on frequency translators.

One final comment... if your signals are dropping out, it means just one thing.  You need a better antenna.  That goes for both TV and FM.  Unless they're located behind a hill or mountain that blocks the signal, anyone within 60 miles of Sutro Tower should be able to get solid signals on all 11 TV channels that transmit from there if they put up the proper antenna.  You should get the three full power stations on Mt. San Bruno, too.  There have been many reports of good signals at even more distant locations than 60 miles... like north of Santa Rosa, Pacific Grove, Gilroy and several from the Sierra foothills.

Hi,

I am NOT trying to suggest that KDFC is on Sutro, it is not, just that the Weather changes also affect FM at the same time as KBCW 44 (P45) and KQED 9 (P30) even though the FM band is so far apart in frequency.

With the physical channel changes there will less problems this Winter, but there will be problems.

I intended just to send a heads up that some people will have problems this Winter, that the increase in height is not solving Winter reception problems.

I have good reception in the Summer with my UHF antenna left in one direction. The rotor will be in use from this point on. And another antenna (Bookshelf top) will try and get 30. That did not work last Winter and I could not find any direction to point my main UHF antenna in to get 30 some of the time.

Larry or some one will report on the power levels, I understand that they all are at their final power level.

If you cannot get KBCW 44 (P45), can you get KTVU 2 (P44)? These two stations need a physical channel ID to be clear what you are saying. V44 is on P45 so saying just 45/44 is unclear to me at least.

Hi,

I am NOT trying to suggest that KDFC is on Sutro, it is not, just that the Weather changes also affect FM at the same time as KBCW 44 (P45) and KQED 9 (P30) even though the FM band is so far apart in frequency.

With the physical channel changes there will less problems this Winter, but there will be problems.

I intended just to send a heads up that some people will have problems this Winter, that the increase in height is not solving Winter reception problems.

ok here but can't get 45/44 on either set/antennas (always weak even in analog days). 7 still a problem.... sigh.

I don't believe KDFC is on Sutro -- it is less than satisfactory here, even without regard to the digital sub-channel reception. Too bad as it is the only classical music station in a sea of mediocrity.

Anyone know if all stations are up to full allotted power yet?
Strange that KOFY 20 has always been very strong, 89 to 94 meter reading while other Sutro stations are generally in the range of 60 to 75 at best.

Hi,

Sutro is done, the leaves are falling.

I am starting to get a picture of what my reception will be this winter.

KQED (30) reception has been spotty and gone completely some of the time in
the afternoons (~ 3 PM, NewsHour).

KBCW (45) was also gone Thursday but came back for the 49'ers game.

KDFC (FM 102.1), KDFC-HD2 is dropping out (Silence at times) this morning.

In the evenings and nights KQED and KBCW are OK as is KDFC-HD2.

So, there will be problems for me with an antenna in my attic this Winter
just like past years.

Rotating my UHF antenna may or may not help, it did not just before the
49'ers game when I was in a panic.

Thanks for the comment. I think there are two signals stepping on each other .... maybe I need to point some kind of directional antenna at Diablo ...

perhaps someone can comment on receiving FM from two transmitters on the same frequency.

I remember that there is a capture effect perhaps allowing the stronger station to be received.

FWIW I have a single antenna on my roof which is probably a Winegard Chromstar
2000 series UHF-VHF-FM. I split the FM signal at the base of the antenna and run
a cable directly to my receiver. FM reception has never been an issue before,
during, or after the transition. KDFC is one of our favorite stations and has
always been crystal clear. We live in San Jose (Evergreen Valley).

TV is divided into 3 chunks: VHF low, VHF high and UHF.

VHF low is channels 2-6, and spans 54-88 MHz (there is a 4 MHz gap between
channels 4 and 5 - 72-76 MHz - that is used for remote control cars and stuff).

VHF high (7-13) is 174-216 MHz, and UHF is 470-698 MHz (17-51).

FM is 88-108 MHz. That places it just above the top end of channel 6. A VHF low
antenna generally will work for FM, but won't be quite as good as a dedicated 3
meter band antenna. The bigger problem is that VHF low antennas are almost
always combined with VHF high and UHF antennas, which usually makes them
performance compromises. You try and do 3 things and you won't do any one of
them really well. :)

Other trivia:

TV channel 2 is just above the Amateur 6 meter band, from 50-54 MHz. After the
FM band at 108 MHz there is an aviation communication band where they still use
AM. That's 108-137 MHz. Then, between 137 MHz and 174 MHz are various land
mobile sub-bands, including the marine VHF band, railroads, the amateur 2 meter
band from 144-148 MHz and the NOAA weather channels around 162 MHz. Above
channel 13 is a land-mobile band and the amateur 1.25 meter band from 222-225
MHz.

Digital, in general, has always been a bit of a trade-off.

Our senses are analog. In attempting to create any digital representation of the
physical world there will always be quantization error. Then you pile on top of
that the various lossy compression schemes: they leverage the imprecision of our
senses to reduce the amount of data used to transmit the signal - they throw
away data regarded as unimportant.

The flip side of that trade-off, however, is error correction and noise immunity
(at least up to the point where the digital signal is converted back into
analog).

HD radio makes do with a relatively limited data rate because it has to ride on
top of an existing analog signal without widening it. ATSC, by contrast, gets to
use the entire 6 MHz channel to transmit the digital data stream. If you were,
say, to set up a 300 kHz wide QPSK channel, I dare say you'd be likely to be
able to run two channels of iTunes quality joint stereo audio easily. But you'd
have no analog listeners at all.

The FM band is near TV Channel 6 so my 2-13 VHF antenna in the attic pointed at Sutro (> 30 years) gives me a useful KDFC HD signal.

Brisbane looks like parts of it have a clear shot at Diablo so a VHF antenna pointed at Diablo might help, but use an old 2-13 one and check that the FM trap is not active. Perhaps a FM only antenna would be the best route.

First, move a FM dipole around your house, you might find a good location. I get too weak a signal with a FM dipole, too much noise when the volume is turned up. That's why I got a HD radio. But at lower levels the noise is not so bad.

http://www.avsforum.com/avs-vb/showthread.php?t=971339

Until I put the VHF / FM splitter first in line off the antenna I could not get a HD reliable signal that my Sony radio could lock on.

KDFC-HD1 selected will drop down to the analog version if a good signal is not present. KDFC-HD2 goes silent with no link able signal.

And YES, KDFC-HD2 is commercial-free.

Note, "HD" is a marketing label, not "High Definition". The old FM signal has a wider frequency response.

I have a clear shot here in the South Bay to Diablo, I wonder which transmitter I am getting.

I've been happy with a Winegard PR-6000. In case it's no longer available, it's
