Okay, that sounds familiar, John. It had pots that may have been belt
driven that increased or decreased the resistance depending on rotation.
Something else I remember - the person put a plastic garbage can over it
to keep out the rain. I know why he did that. I just find it amusing
that I remember that detail.
Let me ask one other question before I get to comments. I actually have
one U-100 and one U-110. Is this going to be an issue? I'm not sure
what the difference is.
@AA5AM: Don't put too much into it. I thought someone might remember
it off the top of their head. There are several solutions that I got
that may be better than what I was looking for.
@KL7XJ: I vaguely remember the SatEL being advertised in the Journal.
I think it is time to renew my AMSAT membership and maybe purchase those
DVD's.
@VK4HHH: I have looked at K8DAV's setup quite a bit. I got myself
confused thinking it only worked over a parallel port (that is an issue
but can be overcome unless portable/field). However, I realized the
basic stamp controller worked over a serial port (not an issue). I may
go this route, but I'm still looking for options. Will this setup work
using SatPC32 which was my preferred tracking software when I was
satellite active?
@KO6TH: I like your approach. Let me see if I got my head wrapped
around your design - serial interface to the FODtrack board which then
controlled your controller? That's pretty cool.
@VU2POP: Very nice homebrew tower and rotor setup.
Still working out my options. I just want something simple that I can
take to the field using a modern laptop.
Lot's of good suggestions here.
Downloaded the form to renew my AMSAT membership too.

couple and one even auto track (but a LOT of work)

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?
