....or ERROR in LO frequency? Please let me know if I have an idea that won't work or if I've got something else wrong.
I'm trying to setup a FTA receiver at my parents. The setup there is a mesh 7.5ft dish with C-Band only feedhorn and LNB. There is a second coax there for Ku. So here is what I'm attempting....
I want to use an old DirecTV LNB from an 18" dish on the 7.5ft dish. What I'm attempting to do is mount the LNB slightly off center of the focal point. In other words strap it to the side of the C-Band feedhorn LNB assembly. I'm figuring if this LNB will work with an 18" dish off center feed it will work just fine slightly out of the focal point of the big dish.
So I hook up the LNB to the spare coax from the big dish and connect the other end to the DVB receiver. I positioned the dish on G10R and peak the settings using the sat finder on the C-Band LNB. I then move the DirecTV LNBf to the focal point. I have my sat finder at the dish now connected to the Ku LNBf and move the LNBf to find a place where the meter jumps up and the tone changes in pitch and level stating it has found a signal. Back at the receiver I get a signal but no quality indication. So I tried moving the LNBf to different positions, changing orientation, changing F connectors etc. to no avail.
Thinking this, in theory, should work just fine I figure something else is wrong. I swap coax cables (no help). My thinking is I am doing something wrong in the way the LNBf operates; namely it does not have the same L.O. frequency of 10750 MHz like a standard LNB for "big dish" setups. So I start searching the forums and come across this thread:http://www.satelliteguys.us/showthread.php?t=107462
Here I read some interesting items. Namely Pete's post of a DBS LNBf L.O. of 11250 MHz. Still later I see 9750/10750 MHz (but I don't think this applies). Another suggestion is L.O. of 10600 MHz with 22KHs ON. This last one has me as what does the 22KHs ON mean? Is this supposed to be 22KHz ON and is this a setting on all receivers? What did the original LNBf devices have as their L.O.?
(The DirecTV LNBf I'm using is part number BSNA5-2108 or 1022995-0002 if that matters. It is the single LNBf with two F connectors.)
I didn't try setting different L.O. as I did not know for sure if this could be an issue and I didn't find the above posting until after I'd put everything away. I did change the voltage to the LNB from 14 to 18 volts (this changes the polarity, right?). The voltage settings also allow for a resistor and the same two voltages. Tried those as well. I did try changing the physical polarity of the LNBf, its location next to and in front of the C-Band feedhorn etc.
Am I on the right track in attempting this? Or is the focal point too sharp? Is it more of a question of Local Oscillator frequency? Or quite possibly a bad LNB in the first place? I don't think it is a bad LNBf but more of how it is setup as both the sat finder and the receiver indicate that they are getting SOME signal.
If anyone has done what I'm attempting, please let me know if/how you accomplished this feat. If it is a LO issue, what do I use and is the 14 Volt 18 Volt the "polarity" switch for this type of LNBf? If so what voltage is the "horizontal" as a standard?
Neat discovery/interesting observation: While playing with the coax connections I connected the C-Band LNB to the DVB receiver (using the Ku coax) and the satellite signal meter (at the dish). The C-band LNB coax was hanging at the dish but still connected to the analog receiver. I did this just to see if I could peak the dish slightly better using the power from the DVB receiver.
While moving the dish back and forth I was viewing the C-band receiver and I was getting a picture on the C-Band receiver! Not super strong like when it was connected directly, but a signal that was mostly steady and in some cases a full color image with sparklies. Thinking I'd done something wrong I disconnected the coax from the DVB receiver to cut power to the LNB and sure enough the picture went away. Seems that there is a powerful signal at the C-Band LNB.

Thanks for the repsonse. The mesh on this dish is the same size as mine and I receive Ku just fine. I have a Corotor II on my dish and am fully aware of changing the feedhorn out.
But you bring up an interesting point; that DirecTV is circularly polarized. I had thought this to be true with the newer "two satellites" setups like I have for my Dish Network (110 and 119 degrees). I thought the single LNBf dishes were H/V but checking Lyngsat shows the Echostar and DirecTV birds are all L/R circular. Quite possibly I was thinking Primstar.
This solves my problem. Maybe an LNBf from a Star Choice Canadian system?

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!
So let the game continue!
The last song was added by Bobby who posted...
One Meat Ball - Andrews Sisters
CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!
Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game
Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.
Example:
Long Live Rock and Roll -- Rainbow
Rainbow in the Dark -- Dio
Another example:
Ride the Lightning -- Metallica
Lightning Strikes -- Ozzy Osbourne
Get it?
An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

I was reading this article
thehill.com
That said this-
Last summer, for the first time, streaming services like Netflix and Amazon Prime claimed the largest share of the television viewing audience, surpassing both cable and broadcast TV. Streaming captured 34.8 percent of July viewers, according to Nielsen data, compared to 34.4 percent for cable and 21.6 percent for broadcast.
And then, sometime in the second half of 2022, cord-cutters became the majority. The share of cable and satellite television subscribers dipped to 48 percent, according to a report from Samba TV, a television technology company.
Now I do not consider those with YTTV and the likes, Cord Cutters, but they still do not have Traditional Cable/Satellite delivered Live TV, so I decided to do the math.
There are, now, 129 Million Households in the United States.
In 2015, there were 100 Million Cable/Sat Subscribers , no streaming Live TV Service.
Today, there are 66 Million Live TV subscribers, including Cable, Satellite and Streaming.
Roughly, Streaming Live TV has 14 Million subs including all of them.
So that means, Cable/Satellite now has, roughly, 51 Million Households
So in just 8 years, lost 49% of their subscribers and by the end of this year, expected sub count to be, roughly, 45 million households.
That means a total loss of 55% since 2015 at the end of 2023.
But out of 129 Million households, 45 million will mean only 35% will get Cable/Satellite Delivered Live TV by the end of 2023.
Imagine what 2024 will be like.

Some interesting information was in this article-
This first-
The total pay-TV sector (traditional service providers and virtual MVPDs) shed 885,000 subscribers in Q2 2026
So with the loss of 2.03 Million in the first quarter, already at 2.915 Million gone this year, two quarters left to report.
#2-
The segment ended Q2 with 61.51 million subs comprising 27.5 million cable video subs, 21.42 million vMVPD customers, 9.56 million satellite TV customers, and 3.01 million telco TV subs.
There are approximately 133.97 million households in the United States, according to recent YCharts US Households Data from mid-2026.
That means more than 72 Million households do not have a paid live TV service, about 54% of the total.
What is worse, 7 years ago, paid live TV had over 80% of the population subscribing ( about 100 Million), almost all were Cable/Satellite customers.
Today, only about 37 Million subscribe to Cable/Satellite, less than 28% of our population.
#3-
At one time, Satellite TV (Dish and DirecTV), had about 34 Million subscribers added together, now, 9.56 Million.
That is over a 70% loss for those who subscribe to Satellite TV.
For Cable TV, not as bad, since they have broadband to help against the losses ( bundles), but as more options appear ( 5G, fiber, starlink, etc), I expect a big increase in those leaving cable.
Also expect YTTV to really start gaining even more subscribers, for those who still wish to have a live TV service, based on price point and it is a really great service.
50M subs might be the 'floor' for US pay-TV
Fifty million-plus subs could serve as the 'floor' for US pay-TV by 2030, reckons MoffettNathanson.

Agents need appropriate context to make what would be understood as the correct read in a situation like that, and that Gemini answer was a clear miss on that front.
That said, we've also seen Musk (and/or his team) put his thumb on the scale (or just release a very poor product) with his own deployed AI since:

In the end, it's all a tool. Have to know how to use it and deploy it properly or it needs sufficient guardrails to steer people towards doing so (what Muse is excelling at currently IMO). I'm routinely interacting with several agents a day operating various processes locally and in services I use, and there are numerous others silently spun up to perform actions or satisfy requests from my prompts.
Related to earlier discussion in the thread on leveraging local inference: this kind of analysis happening behind the scenes is something everyone will have built into Windows, IMO. Most people won't see all of this, just the results, unless they want to dig into how the fix was chosen. Stuff like this will be standard as agents get local system access baked in, and more of the inference itself moves on-device.
