Hi-
You will need a way to get the diseqc caommands onto coax- you could use a DVB-s receiver card and freeware like DVB Dream- which allows you to input a string. TSmover is another program- I believe it works with
twinhan cards.
If you had a manual coax switch, you could move first az then switch to move el. Store locations by making the sat names up, and use diseqc 1.2.
You could fabricate straight pipes by chopping off the bent portion and scabbing on an extension.
Years ago I tried to make an az-el with two inexpensive tv rotors- remember the RS model? Unfortunately, the servo loop gain was way too high, and they hunted allmost all the time.
