Somewhere I came across a setup for a simple "itty bitty" radio
telescope a number of years ago. Its purpose is educational. Basically,
it consists of a discarded 18" dish, power supply, and a satellite
signal finder. I happen to have a Channel Master 1004ifd finder, but it
gets its power from the LNB, which apparently gets it from a satellite
rcvr. I have no rcvr. Is there some simple inexpensive 12v dc power
supply (battery pack) that I could use? I would guess that it would need
a connector of some sort to hook to the LNB.
