Hello Joel

Many TV rotators have similar construction like  Alliance U110 &  Stolle
I have adapted the Stolle for the the elevation , 
have also a position feedback indicator to this Stolle with suitable gears

Subject: [amsat-bb] U-110 Rotor Setup
 
I am looking for an old article regarding the use of two U-110 rotors for
satellite operations.

I have gone through all my old references and cannot find what I'm looking
for.

Basically, it was a setup using two U-110's (or it could have been two
U-100's).  The homemade controller used either toggle or rocker switches and
had a digital readout of AZ/EL using DVOM's.  As far as I remember, it was
all manual.  I remember seeing this in the back of some publication, but I
cannot find it.

Does anyone have any inkling of and idea what I'm talking about?

73,
