Calculating LNB Output Frequency (Project Part II)

I'm trying to figure out how to know what the LNBF output frequency is for a given transponder, and in particular what's realistically the maximum frequency I should expect.

Using the maximum FTA downlink frequencies I could find:

Max CBand Transponder: 4192 MHz
Max KuBand Transponder: 12180 MHz

... Here are the calculations I'm doing. Anyone know if these are correct?

(C LNB L.O.) - (Transponder) = 5150 - 4192 = 950 MHz
(Transponder) - (Ku LNB L.O.) = 12180 - 10750 = 1430 MHz

... so, that means that the highest LNB output for C band comes from the lowest transponder frequency, and the highest LNB output for Ku band comes from the highest transponder frequency. Right?

Min C Band FTA Transponder: 3706MHz

5150 - 3706 = 1444MHz

The reason I'm asking is because I've been reading conflicting things, and more importantly that the lnb output range is 950 - 2050, and I'd like to know what the realistic output range is. It might not make much of a difference, but if I'm going to play with the LNB output, it's nice to know my max frequency is 1.5GHz and not 2.0GHz.

Any reason I should be worrying about 2.0GHz? Looks like 1.5GHz will be enough.

Whew. Thanks for any help from you folks that have spent too much time with this hobby. :P

Radar, bandstacking is great because it allows the LNB(F) to send both polarities down the same cable at the same time. No polarity switching is required. The LNB(F) just sends the vertical transponders normally and "stacks" the horizontal transponders at a higher frequency. Therefore, both polarities are always there, and the cable may be split or looped through with both polarities intact. Of course, the added complication is that the signal path must be capable of passing about 2.2 ghz instead of about 1.5, and the horizontal transponders will be at unexpected frequencies (above the normal range). A blind scan receiver will usually take care of finding them.

TRON,

I do understand the theory and its uses/applications, but what eludes me is how they are doing this inside the LNBF. The internal circuitry to get the H TPs on the higher frequency. Is there a separate internal oscillator? I have brushed into several explanations of this before, but so many descriptions were vague and incomplete or they contradicted the others. So, I never found a really accurate explanation.

I can see the utility of bandstacking for the DBS band, where there isn't anything in that upper band, but it seems to me that it wouldn't be as useful for other bands. Ie it seems like you'd at least lose the capability of receiving out band, ie such as locking some transponders in the DBS band with a regular linear lnb {this could be good or bad}. But the existance of signals in the upper band would also seem to be an issue relative to interferrence, although I haven't thought that topic through. But what I was thinking, was that say you had an 11700-12200 lnb that was putting one polarity up at 12200-12700, it seems to me that if you have strong signals in that upper band, that they will leak through and interfere with the polarity that is now sharing that band. Ie, I'm skeptical that they could have a sharp enough bandpass filter to keep the upper band out of what is sent as the lower band.
I'm sure that they probably made a serious effort to avoid such problems, but I just wonder how well it can work in practice.

I'm not sure, but I believe that there are two oscillators at work in these LNBs. There are two L.O. frequencies, i.e., 5150 lower L.O. and 5750 upper L.O. on the Eagle Aspen B1SAT C-Band LNBF. Many receivers don't have a provision for bandstacked LNBs, but I've found that using either of the two L.O.s will get you the channels that are there.

interesting read. ive seen cband freqs on lyngsat in the 3400 range (circular @ 40.5w) and ku freqs in the 10 000 range. from reading this i can see a wideband circular would be needed for the cband but what kinda lnb would translate the ku fraqs to usable IF.

crackt out,.

most C-Band LNBF's will go from 3400-4200 so that works. I know the GeoSat C2 does. Its listed on the specs

Also some receivers have it defaulted to those numbers too when blind scanning. Coolsat 5000 defaults to 3400-4200 with a 5150 LO Frequency. I forget if the Pansat goes that low. I know the Pansat grabs stuff in the upper 3500 through the 3600 but forget if it tries lower than say 3550

Song Name Game Part 3!

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....

NCIS

Anyone else watch this show? Any guesses as to what was in the box Gibbs gave to Abby that was on her desk? It look liked it was glowing.

I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

I don't think Tim and Tony are that far apart in Age ...

Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)

Tony has changed, he's been running his Security Business ... I'm sure he has grown up.

Give it time ... your judging the New Tony from the old Tony.

It sounds like Tim won't be around the Team much longer either.

$6.3 billion in crypto stolen by hackers

This should hit a lot of folks with a dose of reality. I can only imagine how much more common this will get as AI progresses.

I read several stories on this and most are clear as mud. They say a lot of the stolen bitcoin has been "locked out" and that everyone will be made financially whole. I guess time will tell if either of these statements are actually true.

The "Secure Asset Fund" had about $1 billion in reserves... in Bitcoin.

The fund started in 2018, so it may take a while to make investors whole, much less replenish the fund.

New report states 29% of vehicles being traded in are under water

It states the average amount they are under water is OVER $7,000. :eek

Personally, I tend to be the type that drives a vehicle for a lot of years....do my own oil changes and other fluid changes. Just replaced the spark plugs and a couple coils. Youtube is great for things like this.

Hopper 3 with Hopper plus internet connection problems

Over the past few weeks, I have had problems connecting to streaming services (Netflix, HBO et al). When I go to the TV's native Channels, I have no problem. The Dish internet troubleshooter shows I have a good internet connection. I'm wondering whether it's an issue with my internet provider or a problem with the Dish software on the Hopper Plus. Anyone else seeing this?

I have a DISH Hopper 3 (Software H713) with Hopper Plus (Software P15403). I have not tried streaming services but I primarily watch TVB Jadeworld international package which is only available by streaming and when I have an issue, I usually have to go to a non-streaming satellite channel first before the streaming channels will work again. What software versions do you have and what is the error message if any are showing on your screen? or is that Dish downloading logo just stuck and never finishes?

Did it ever work correctly before? Hard to say what the problem is. Usually for streaming, it will show the Dish logo with lines sweeping down to show downloading, never seen the circle issue. Did you try a manual reboot, red button reset, power cord unplug/replug to see if it makes a difference.
