Please tell me:
1) Which are the bands of frequencies of decoder D9236 works?
2) Which is the width of the F.I band of this Receiver?
3) It only works with C band or K band or both?
Any advice will be much appreciated,
Zerok
I have one D9236. The other person having them as confirmed to me, by himself, is our member named IPTV. He has, as told, fixed many of these IRDs and got them out of their Factory (wed)lock. Now those D9236, I think, must have been working well and I expect, thru the help of our friend IPTV ( his hotmail add. can be given only after his approval ), some day, very soon, my D9236 will come out of the dead (wedd-lock) fixed preset of "0". Now I come to some of your questions point by point :-
1) As far as I know about the satellite technology the receving frequencies are to be decided by two factors a) Which LNB you use and
which is the IF bandwidth of your receiver. Normally all the IRDs work between the IF bandwidth range between 950-2150 MHz. So if you use C Band LNB the IF of your receiver will tune the frequencies of C Band. Similarly the IF of IRD should tune to Ku Band frequencies if your dish has Ku Band LNB attached.
2) Scientific Atlanta made D9223, D9234, D9235, D9834, D9835 all have the IF range or Tuning range between 950-2150 MHz. Can any one, please tell, why the SA will differ the IF range of D9236 ?
3) As told earlier the reception and tuning of the frequncies by IRDs depend on IF bandwidth and LNB frequencies. If the LNB is of fixed frequency then the IRD should tune to a fixed. If the LNB is of Universal type such as having a range of 9750Mhz-10600Mhz the IRD will tune to the whole of KU Band T/Ps, provided you enter the lowest and highest frequency range of your LNB in the parameters. One must keep in mind that normal channels or transponders are of QPSK type in contrast to earlier DPSK type. So you should enter QPSK normally, if yor IRD asks for it. Some IRDs are auto also.
