If I saw an image of Manny or Frank, I bet I might remember. The names alone, I really don't...

Fond memories of going there, then to a tropical fish store not far away.

Just spoke with Cliff from Solid Signal and he said that a Pico Macom, not a substitute, would ship. And, the eBay purchase of the Winegard CS7750 also appears to be as advertised (not the "replacement" model, thankfully).

The Winegard CS7750 is a 20 year old UVSJ design. There are far, far better ones available today for only 2 or 3 bucks.

It's a completely different device that the CC-7870, the eBay seller is incorrect.

Thank you ProjectSHO89.

Insertion loss of just .3 dB (on the CS7750) is what was appealing in the discussions I read... Which ones would you recommend, and if not asking too much, why is the older design not desirable?

Conditions between here and Walnut Grove have been rather interesting lately. While KMAX 31 and KQCA 58 continue to be solid, KVIE 6 and KXTV 10 have been going up and down in strength, but opposite of each other. When KVIE is strong, KXTV is down at the cliff edge, then KXTV will get strong and KVIE will go down to right around the cliff edge, kind of fluttering between above and below. Since they are right next to each other in frequency (9 and 10) I would expect the signals to act very much alike, but they haven't been at all. KOVR has been varying from very strong to below the cliff edge this past week, making as much as a 9 dB change, 23 db down to 14 dB, from day to day.

Signals from up north - KTLN, KRCB and KEMO - have all been down this week, while those from the South Bay have been stronger than usual. KAXT 1 has been seen a lot more than usual this past week.

How have things been looking up your way this past week, Chuck? Anything unusual observed?

TonyB... since you're at the outer edges of the coverage for the Sutro/Mt. San Bruno stations, do you observe a lot of variance in signal strength?

Yes, it's been crazy here for a couple days but this morning seems more typical. KKPX was in here for almost 2 days straight. I rarely see it for more than a short time and frequently not at all. Walnut Grove has had problems in the middle of the day. Anything from Sutro has been terrible. Even Salinas has been below average.

Hi Larry and Chuck.

Honestly, I haven't noticed. That said, I got a TiVo Mini last night, and I've been busy with it, not so much TV viewing... I just put the TV on in the bedroom, through the Mini (network to the TiVo Roamio), and all seems "normal" for out here. Fox (2.1) is challenged, but that is not uncommon for me.

BTW, anyone wanting a Mini, they now have Lifetime service and can still be had for 88 bucks at Fry's, with Best Buy and others matching.

I have more "things" from Quement than from Fry's.

I still have part of a spool of enameled wire (14 or 16 gauge) that I bought at Quement that I used to wind the inductors for the crossover networks in my transmission line speakers back in the early '80s. Speakers and crossovers are still working fine to this day. Had to replace the surrounds on the woofers once in that time.

I'll have to make note of the marine layer vs conditions in a chart and see how they compare. I think you might have hit the nail on the head here.

Monday night, I observed two dropouts on KVIE. I can't remember the last time I had any on that set. I didn't check KXTV. 6 was below the cliff for about 5 seconds total.

With a little more effort, it seems that I might be able to get Fox 35.1. Before I attempt to do so, does this Fox channel telecast NFL games, like Fox 2.1?

Edit / Add: For those who don't know, there will be a solar storm heading our way this weekend, I think Saturday. I suppose we should expect disturbances to our OTA reception...

KCBA has all the same network programming as KTVU.

Solar flares don't affect TV reception. They mainly affect shortwave propagation. All these news stories the last few years about solar flares are the result of much better solar monitoring by new satellites. The media blows these things way out of proportion. There were plenty of big flares during the higher solar cycles of 1979 and 1991 but you never heard about them.

Chuck, thanks for the info on KCBA and solar flares.

When I was getting KCBA last night (early morning), it seemed to have different programming (very poor reception) at that moment as compared to KTVU... If they get the games, I think I'll put in the effort to try to get it as a Fox back-up for us...

They have the same network programming as KTVU but like most network stations, they run other programming during none network times.

I checked this Sunday and the 49ers are the NBC Sunday night game. KCBA and KTVU are showing different games at different times on Sunday. KTXL Fox 40 is showing the same game as KCBA. The following Sunday it's back to Fox and all three stations show the 49ers at 1pm.

Chuck, you are helpful in different ways, thank you.

I'm more into college ball, but do watch some NFL games though... KTXL is way out of my ballpark down here, not even on the TV Fool report.

Whether I go north to Sutro, or south to Salinas, I have 2 edge to deal with. That all said, I'm getting reception here beyond my expectations, given that my set-up is nothing approaching elaborate...

450 MHz (Two-way) most likely

Very similar anatennas are located all around Las Vegas at many of the water pumping facilities. So, a guess might include data transmission to a central facility.

Wanting a strong FCC to say no to the Wireless lobby. Keep the tv broadcast band for ota television broadcasters.

This antenna is call a yagi and could be for a lot of different uses. It could be a receive antenna for a data service, a base station for two way radio system (most likely).

Instead of starting a thread elsewhere, and I still might do that, I figured I'd seek input here first...

What are the thoughts of 2.4 GHz transmissions interfering with OTA? Most of what I read is that it should not be problematic, but then I do find some tidbits that say otherwise. On the DSL Reports forum, a poster responded:

"Our area has poor TV reception, and many customers have amplified antennas in their attics.

I've found that some of the amplifiers pick up and resonate with 2.4 signals, causing a feedback that is noticeable on the customers TV screen (when tuned to certain channels) and noticeable as increased packet loss on the 2.4 GHz link. A simple spectrum analyzer did not detect the problem, because it is only there when the 2.4 GHz radio is transmitting, and the reflection from the TV amp was masked by the original 2.4 signal.

When the 2.4 GHz radio is turned off, the TV interference clears up. When the antenna amplifier is turned off, the packet loss goes away."

++++++

I suppose like most I have a 2.4 GHz wifi network. Actually, it's dual band at the new home... What prompts this inquiry is that while unpacking more stuff, I just found this Cisco antenna that a friend gave me:

http://www.solidsignal.com/pview.asp...-(air-ant24120)

http://www.cisco.com/c/en/us/td/docs.../ant24120.html

Not sure I'll have a need for this antenna, but I'm curious to know if it might compromise our TV reception...

KCET and KLCS to Auction Off Spectrum

http://labusinessjournal.com/news/20...tion-spectrum/

Quote:
Both KCET and KLCS, headquartered downtown, will continue to operate under separate, non-commercial licenses.
Quote:
However, the National Association of Broadcasters has filed a lawsuit to challenge the auction, so there is a possibility it may not immediately proceed.
Lawsuit, what lawsuit.

The people who write the laws are always clear and cannot be challenged. Wait, there is a election coming up, the lawmakers want the money to be re-elected.

This is technobabble. Sounds plausible at first read but it has no technical basis at all.

I had 2.4 GHz and 5.7 GHz internet equipment on my tower with the TV antennas for awhile and there was no interference to the TV.

So KCET goes independent of PBS and finds it doesn't have enough revenue without PBS subsidies. Now they think that a one time cash infusion from the auction and merging transmitters will solve their ongoing revenue problem. Nothing wrong with that business model.

Thanks Chuck. Most of the commentary was just that - 2.4 GHz would not pose any problems. Logically, this makes sense, but there were a couple dissenting opinions...

If I decide to proceed with mounting and connecting that Cisco antenna, I'll do so with no TV reception concerns. Thanks again.
