Do Sats have their own ID's?

Posted here cos I have a TM 6900 Super.

When I do a blind search on 39E I don't get stuff on 40E and vice versa. But when I do blind searches on 9E and 10E I get the same channels on both.

Is there something I need to do to get the box to get it "right"? Or am I being picky?

39 east is Hellas Sat 2 and 40 east is Express AM1 so totally different.

9 east and 10 east is hotbirds which is the reason you are picking up channels on a blind scan from both of those,, but this could also be your dish size that is the problem here as if your aligned on 39.E it may not have a strong enough signal to pick up your channels on 40E and vice versa.

Think yall find all channels on 40e are C band-u will only pick up KU channels so those on 40e wont even show

Well, go to this site, give in your adress
Satellite Finder / Dish Pointing Calculator with Google Maps | DishPointer.com


you can select which satellite, you can lookup dishzise and so on.

Prob yr dish, LNB and alignment is not 100% for the thing you want to do.

Keep us informed !

Hi martico,

Do Sats have their own ID's?

I've never really looked into that fully... but I presume that all satellites must have their own ID's... but I suspect that only dedicated Provider STB's can use that information... I doubt that your TM 6900 Super can recognize/distinguish/filter those ID's when you do a blind search...

When you come across satellites as close as 0.5° apart to as far as 2.5° apart... you will always run the risk that your receiver will detect frequencies from a neighbouring satellite and download them as well... so you must alter the search parameters in 'Blind Search' accordingly...

Regarding the instance you mentioned... Eurobird 9A at 9.0°E and Eutelsat W2A at 10.0°E... if you look at the frequencies for both satellites on KingOfSat/Lyngsat/Flysat you will notice that they DO NOT use the same frequency range...

Eurobird 9A at 9.0°E only uses frequencies between 11.700 and 12.500 whereas Eutelsat W2A at 10.0°E uses frequencies between 10.700 and 11.700 and also frequencies between 12.500 and 12.750

So, if you don't alter the parameters of 'Blind Search' in the menu... your receiver will detect everything from both satellites... what you need to do on a 'Blind Search' of Eurobird 9 at 9.0°E is to set the search parameters to...

Satellite List: 9.0°E Eurobird 9A
TP: 11.700 ~ 12.500
Pol: ALL
Mode: ALL

Then you will have to 'Blind Search' twice on Eutelsat W2A at 10.0°E and set the search parameters to...

Satellite List: 10.0°E Eutelsat W2A
TP: 10.700 ~ 11.700
Pol: ALL
Mode: ALL

Satellite List: Eutelsat W2A
TP: 12.500 ~ 12.750
Pol: ALL
Mode: ALL

However you will come across situations where two neighbouring satellites (within the 0.5° to 2.5° proximity range) will use the same frequency range... then things become a bit more complicated...

For example... take a look at the other scenario you mentioned regarding Hellas Sat 2 at 39.0°E and Express AM1 at 40.0°E... the close proximity of these two satellites is now no longer a problem as Express AM1 uses hardly any Ku band frequencies anymore... but about a year ago frequencies from Express AM1 used to show up on a 'Blind Search' of Hellas Sat 2 and visa-versa...

Also of interest back then... due to the close proximity of these two satellites and their joint use of the same frequency range there was also another unfortunate consequence... frequencies from the more powerful Hellas Sat 2 would block out frequencies from the weaker Express AM1

In summary, if you are going to 'Blind Search' any satellite it is always a good idea to check on KingOfSat/Lyngsat/Flysat at the frequency range/s of the satellite you want to 'Blind Search' and the frequency range/s of other neighbouring satellites and set your 'Blind Search' parameters accordingly...

I hope this helps...

Best Wishes,

Thank you all

DrRu, Hmm, I'm sure I was getting something on Ku from 40E the day before yesterday, maybe a feed, but I see what you mean on Lyngsat.

Zorch, thank you especially. I hadn't noticed I could limit the frequencies the 6900 looks for in a blind search. Only had the box 18 months!

And Wolftje, great advice as usual. It's a 1m dish that seems pretty well aligned, e.g. it gets 53E pretty consistently, but maybe a trip up the ladder again ..

Hi Martico,

&
very nice info Zorch !

If you re-align, I would suggest to put in the transponders freq that matter to you.
So when you are alligning and put the technomate into Satellite Menu you choose that corresponding transponder & satellite on which you should allign your dish in order to have max. reception on that transponder. Of course beware, You can have a good reception on a H freq and have bad reception then on V freq. That's why a good digital satfinder with graphs comes in handy in such cases

I can imagine if the transponder is very weak and only shows up in a blind scan it will be difficult to pinpoint exactly what the transponder freq would be (depending on the state/Reception /allignment of yr dish)

trial and error ?

All sats have unique ID's as do all providers. You'll usually get this kind of info from the standard NIT tables. Any stb thats properly programmed should easily be able to identify which satellite a datastream originates from as well as which provider is actually transmitting that source material.
