Something that has never happened before.

It only works if I do a full re-scan.

The signal is below average to weak, but more stable. Not bouncy like a tidal wave.
It works best with the antenna 90 degrees away from before. (The old tower)
That is pointed west of San Bruno Mtn. (Towards the ocean)
Weird.
What do you mean by "KEMO stopped working"?
What other modes do you have besides "antenna mode"? It's interesting that you had to do a full re-scan and that you're getting the Sutro signal from a point west of Mt. San Bruno. Sometimes things just don't make sense.

Here's the reading I get on my HD Home Run receiver:
SCANNING: 581000000 (us-bcast:32)
LOCK: 8vsb (ss=100 snq=100 seq=100)
TSID: 0x01A7
PROGRAM 3: 50.1 KEMO-HD
PROGRAM 4: 50.2 KEMO-DT

Can't get any better than that!

I can't take any credit. It's a function built into Photoshop.

Obviously the new KEMO DTS is on the air but they have not filed for a License to Cover. Normally new stations file the same day they start transmitting. They should make it official soon.

It says "No program", when you enter that channel. It crashed ... with the transmitter swap .... (plenty of signal.)
So I re-scan it. And then it works again.

I do not think the tuner jumps back & forth between the transmitters. They must have some hidden lock code or something.

When I have time I'll check the analyzer on that one, and see what's happening with both signal sources.

Hi Guys,

I'm gearing up to construct San Jose 45 (RF channel 2) K02QX-D on Friday. The transmitter is arriving this week, and I have the tower climber and help scheduled for Friday. We'll be constructing atop Mt. Chual which is adjacent to Mt. Loma Prieta. If we don't get it all constructed by Friday, then I'll try and finish soon after that. Say a prayer!

I was putting together the custom antennas yesterday at home yesterday to make sure it went together properly. Each antenna is actually two Kathrein-Scala CA-2 antennas put on a single boom to provide circular polarization.

Blessings,
Keith

This will be very interesting as I have no experience since the transition with any DTV signals from that location. I used to see KKPX on 65 in the analog days and the signal wasn't very good. TV Fool says K02QX should dB 13 dB stronger than KFTY. If so it should be easy to receive as I can put KFTY in a 20 dB null when pointed down there. As you can see in the image I posted above I have a pretty good shot to Loma Prieta/Chual on this end. All the terrain is the Mt. Hamilton range.

Good luck,

Chuck

All TV signals are less than 50% now, I'm getting no picture. This is a link to my TVFool analysis. http://www.tvfool.com/?option=com_wr...f1f04ee65eb6d0

My window is facing West. I'm using indoor antenna Mohu Leaf. I'm assuming some new tall buildings are blocking the signals? This is a recent problem.

Who knows exactly what's going on but if all was fine before and now you receive no stations then there has been a failure in the antenna or TV. Check the cable to the TV or try another antenna. A paperclip would work with your signals.

I just noticed that Estrella TV is going to start up on KQCA on June 1. KTNC has Estrella Sacramento on 42.2. Does this mean that KTNC is going to change programming?

Chuck

Edit: I see that Larry posted the same thing over on the Sacramento thread.

How long has the Leaf been working fine? Where are you using the Leaf? Is it connected with an extension cable, or is it 6 feet or so away from the antenna input? In one room here, a Leaf worked just fine for about 5 months, then I started seeing A/V dropouts. Changing the antenna height/location/aim was required to receive certain channels. This is often true with indoor antennas.

I see no sign of K02QX from San Jose here in San Francisco so far.

It's not on yet. You know how antenna projects go. Make your best time estimate and then double it.

Is KEMO DTS2 still on? There's been no License to Cover filing yet.

Apparently Keith will have to go back to finish the channel 2 installation down in San Jose.

Yes, KEMO 50.1 and 50.2 are now continuously on the air from Sutro Tower.

We installed the antennas for K02QX-D San Jose RF channel 2 yesterday; however, I ran into a couple snags with the transmitter. It had a connector I never heard of called L27, and I couldn't upgrade FPGA code in the exciter to enable PSIP editing. Also, I ran out of half inch feedlinefor the receive antenna. I was going to instead run 3/8 inch LMR-400 but thought that since I have to go back I might as well get some LDF4-50 1/2 feed line.

Blessings,
Keith

Looks like a Chinese connector. Even Pasternack doesn't sell them. I hope you don't have to order an adapter from China. Maybe you can swap out the connector on the transmitter for an N connector.

KOTR Tidbit

While playing around this morning with antennas I had on KBTV. At the end of a religious program they announced all the stations and times that their program was broadcast. One of the stations they listed was KOTR channel 11. Apparently it must still be on as a cable channel even though they have no OTA station. I didn't know a broadcast station could do this.
