Re: [Phys-l] satellite dish controller

"I assume the whole rig started out as a satellite TV dish
controller, modified to use a rather larger dish.  If that
basic architecture is OK with you, search for TV dish products
(as opposed to astronomy products).  There's plenty of dish
drives on the market."



Right;  I found in an old (ca. 2001) Radio Amateur Mag. an article on 
how to modify a Uniden (Not yours, unfortunately.);  if I remember 
correctly,  to vary the slew rate.

bc, who thinks checking w/ the Microwave "Ham" community (surprisingly 
large!) might help.
