I guess I haven't made myself very clear. For the record, I do understand the LO frequencies. What I am referring to is the default list of satellites and tps that came in
my AZBox from the guys in FL. An example of what I am talking about is Al Jazeera English on what they called Galaxy 25 North America but is really now Galaxy 19. They have that sat set up with a "Universal" lnb, the high band LO freq being 10600. They have the tp that Al Jazeera lives on set up as 11998 MHz, which gives an L band freq of 11998 - 10600 or 1398 MHz. The actual tp freq for that mux is 12152MHz which, with an LO freq of 10750, gives an L band freq of 1402MHz. Same mux within the margin of error for the lnb freq. According to Lyngsat, 11998 isn't even an extant mux on that bird.
The "cheating" I am referring to is the fact that the tp lists in the AZBox default set that I received are set up, at least in some cases, with frequencies that will produce the right L band freq when calculated with the 10600 Universal lnb LO freq while actually being received by a 10750 Ku lnb. While this works just fine in the receiver, it means that the numbers that are actually stored as tp freq's are not the correct numbers. Makes entering new tps on that sat a bit of a PITA.
I was just looking for a set of files with the LO and tp freqs being the correct ones for a 10750 Ku lnb. I actually think that the satellites.xml generator is going to put me on the right track.
Thanks for your time on this. FWIW, the IT912S ALMOST manages to deal with 5150/10750 on the same sat. You can have both sets of tps on the same sat definition and just pick the "antenna" to scan when looking for channels. Once it's found the channel, it always does the right thing and knows how to set up DiSEqC, 22kHz, and 12V switches to receive the channel. OTOH, it doesn't do DVB S2 or 4:2:2 so we're back to "nothing's perfect"
