Hi guys,

problem: Skystar2 Rev.2.6D doesn't tune to high band frequency (frequencies like 12597) but all other functions are 100% OK (it was working perfect at the time of purchase)!

Othe info: Tuner 14/18V ok, LNB ok, cable ok, everything ok and checked.

Driver Ver: 4.3.2 and I have checked almost all other drivers!

PC info: 2.4Ghz Intel, 512M ram and other suitable requirments for ss2.

Please help!!:(

What is the highest frequency you can tune to? Check that the 22Khz tone has not been accidentally toggled to off.

11919 Mhz is the highest tunable frequency (on hotbird). 22khz is on (I tested it using a variety of tuner programs like "b2c2 tunner control" and "progDVB"). I wish somebody would tell me how to make additional checks on 22khz tone, including a way to test it; without using osiloscope.

Thanks.

That sounds like it isn't working then, or could of course be the LNB.

Dear Rolf;

My "Starsat" receiver receives all channels using this LNB and dish!:confused (and shows signal quality of above 50%).:(

OK, we can rule out the LNb then. :) Can't remember the software as I haven't used mine for a while, but is there a transition figure that can be changed for switching to upper band?

Transition figure? would you explain more? is it something like, say a radio button in softwares which enable/disable 22khz?

No, I think that it is actually called 22Khz transition, it is normally set at 11,650, it is the figure at which the receiver is told to switch to upper band.

Sorry, I have no idea about that. The last thing I have decided to do is to get someone solder out EEprom of the card and reprogram it! I have even downloaded the datasheet of eeprom!:( :( but finding a suitable programmer is really an issue!:(

ProgDVB ver: 4.71.5 and DVBviewer, both act the same. I usually test it with "fast sat finder" which shows 0% signal on High band!

The card was ok at the time I bought it and I received more that 1200 channels on hotbird:rolleyes:, then I pointed my dish to UtilsatW3 in order to do "offline-downloading". I did it for about one month without any problems but when I turned dish to Hotbird again, high band was gone! I wanna cry:( :(

Help please

The setting is called switch in the LNB setup menu.

That being the case, it is probably a case for the bin, unless you bought it less than a year ago in the UK, or 2 years in Europe.

Maybe it's a damaged coil?

Well looks like replacement of the coil is not that difficult to an electronics engineer, but have to say that I wouldn't try it, still remember my last effort. :) may be worth trying to source the component though, or alternatively a 22Khx tone inserter, they are not very expensive. http://www.donberg.ie/descript/t/toninert.htm

Dear Rolf and Orthoclipse;

Thank you very much for the care you have taken to solve my problem.

I am going to change coil right now and I have found almost a same coil in a broken computer-power-supply.

I will keep you informed about the results.

Sincerely:)
