47-2 is Festiva TV. http://www.festivatelevision.com/

I have a direct contact at DTV America who e-mails me almost every time something changes on any of their stations (and sends a complete list to me every few months, just in case something gets missed) so the RabbitEars listings for the DTV America stations are usually pretty up to date. Larry, you're of course welcome to use RabbitEars information to update your listings as you see fit.

Yes, the move is complete. I have not seen any more transmissions from Angles Camp.

Does anybody know if a directory exists for AM-FM radio ? With transmitter locations ?
I hear some weird stuff in the car.... from far away locations.
The rock station at 1660 AM ... (guessing Bakersfield ? ) is a mystery too me.

You said something a few years back about amplifiers and the low VHF band. I forgot. Do they work on that band ... or not ?
Is this station a full power one ?

For FM there's this: http://db.wtfda.org/

Not aware of something similar for AM.

Unless Radio-Locator is what you're looking for.

Preamps on low VHF don't improve the SNR because there's a minimum of 10 dB more noise there than on UHF. There's also much less cable attenuation on low VHF. I found that a system noise figure of less than 10 dB didn't improve the SNR for me. Even with my very long cable run the total attenuation was 4.6 dB and the distribution amp NF is 3 dB which is only 7.5 dB total. Adding a 3 dB NF preamp did noting for the SNR.

My summary for preamps:

Low VHF - no help for anyone
High VHF - can be helpful in quiet locations and for long cable runs
UHF - helpful for weak signals for almost everyone

KCSO is a low power station. They are licensed for 3KW but I think they have an STA for 5KW but I'm not really clear on that. I'm not sure what qualifies as a full power station on low VHF. 10-20KW?

Over the long run KCSO from Walnut Grove averages a Noise Margin of about 25 dB. The puts them right in the middle of the weaker UHF stations so I'd say they doing pretty good for 3KW.

I don't why you didn't see any improvement up north when they moved. What antenna were you using?

You can always use AM Query:

KBRE Merced is on 1660 KHz.

When I go there. Two things happen. .. (I don't live there)
I bring my own battery tv, with my own antennas. And see what I get.

Then I go inside the house and compare ... with what I installed around 2005... do re-scans, etc.
The house antenna is one of those VU-2-69 "vee" type/style antenna >>>>>> (6 on each side) or 12 for VHF.
Stuffed in a 3 car garage attic, cable goes to a distribution amp before the phone/tv demarcation house cable area.
So antenna is at 13 feet elevation. Everything Walnut Grove comes in excellent. 9,10,40 are borderline overload.

I guess I thought it would be like the old analog KCRA 3 stronger. But it's 40% weaker than RF 9 & 10 at 100%
Honestly don't think they watch that station anyways

For my battery tv tests I use.
Low VHF ...... TERK TV 50 (8 foot stick) sounds like it has tons of wire/fiberglass loops inside. Contains an internal amp that blocks FM.
This model is a standout for low VHF.
High VHF.......Clearstream 5 or RCA 34792
UHF .............Double bowtie or RCA parabolic 34792

KQCA has filed with the FCC for their post repack channel 23. They are the first to do so in the Sacramento area. They will be using the same broadband antenna that they use now.
