Dave is correct about the IF freq, but: the local osc in the LNB
covers two ranges: 13 to 18 VDC it will osc in the low band, 22-28 it
will osc in the high band. The LNBs I've seen use an signal about
20khz sent from the satellite reciever to switch polarizations.
Adjacent channels are oppisitely polarized, circularly.

Hi Goup de KJ4UO.

I picked up on for the Direct TV disk with the LNA. The LNA states a frequeny
range of 19 to 23 cm.

I understand the the LNA gets it power from a DC voltage that is transmitted
down the line.

My questions:

For the DC voltage on the cable, how much is required and how much is the max?

What is the IF down converter frequency?

Can I use my FRG-9600 which has continuous coverage from 60 to 934 MHz as an
variable IF to decode voice data?

In general is there a good site to return to and get technical facts on DT
equipment.

Thanks,

Paul
