what frequencies are going to the ird from the lnbf (sl3s)? i have a spectrum analyzer and im trying to figure out what i should be seeing when i do a sweep from 150mhz to 2150mhz? should i see Ka and Ku at the same time or do i need a receiver that can switch to 13v/18v and also a 22khz/0khz for polarity? what should i see as far a sats/transponders/bands when i do a freq sweep from 150mhz to 2150mhz? i do think i see 9 transponders from 870mhz to 1870mhz but i not sure. here is some more info i found but not sure if it applies to my specific sl3s lnbf L-band: approximately 950 - 2000 MHz C-band: 4000 - 6000 MHz Ku-band: 10,700 - 14,000 MHz Ka-band: 18,000 - 20,000 MHz LNB between 10.7-11.7 GHz can be easily seen in 950-1950 not sure if this is correct though so any info would be nice to have thanks ps local oscillator frequencies would be a GREAT help.
