Basic Stamp2 data collection
Hi:
I'm trying to fire up a Ku band LNBF to do some experiments for some
kids in tracking the Sun and Moon and other stuff. Does anybody
knowwhat the voltage requirements are for a portable battery powered
system might be? Just for the LNBF. We can adjust the dish manually.
I really need some help here. The thing is narrow band and I have a
receiver built for it. I just cant yet fire up the LNBF because I'm
afraid to until I get this figured out. I'm using the A/D system from
parallax and Selmaware to get data and am frustrated because no one
seems to know. I think its 12 to 18 volts and not much amps and I
could use a little regulated and filtered dc ps that I got from Ocean
State Electronics. I'm anxious to roll this thing.
Thanks for the help
Jim

The voltage source for the Ku band (and C band) LNB on my
system is 20V. The current on the C band LNB is 100mA. I don't
use the Ku band but I suspect the amperage would be about the same.
