Hi Floyd,
Domenico's advice is quite good. I also wrote a section on aligning a
g5500 az rotator from scratch, its at the bottom of this post:

Hi Floyd, KC5QBC
With the upper assembly separated from the lover part of the rotor
rotate the azimuth motor until the position of the slider of the 500
ohm potentiometer comes mid way i.e. 250 + 250 ohm i.e. until it
will show the same voltage of about 3 volt betwen terminals 1 and
2 and terminal
I like about 10 feet of steel tubing mounted as shown here:

My Cushcraft Oscar 2M/70cm elevation rotator had a aluminum crossboom at 50
inches in
length x 1 5/16 inch in diameter.
I would recommend a fiberglass crossboom vice aluminum to keep detuning of both
antennas to a minimum.

Mike,
Think to equalize the weights- If you have a large 2 meter beam on
one side, that should be the shorter...IE The 440 should be longer as
it will be lighter. Same with the front and back...
This will have the rotor work the easiest and let it survive a lot
longer...Balance them.

Not sure there is. I have had antennas mounted on 8 foot TV mast as
well as 4 foot cross boom PVC material. When you think of it how far
apart are the antennas on the satellite. I mount them on the end of
boom in a "X" configuration regardless and it always has worked for
me. I will be interested i

Jeff, KB2M,
I am sending the schematic for the G-5500 separately.
Disconnect Azimuth and Elevation wires 1, 2, and 3 from the Control box.
Check the resistance across the 1 and 3 leads. It should be 500 ohms.

I have sent to you the schematic diagram for the G5500 but the message
bounced back to me because your @comcast.net don't match with my

By the way and first of all check if you have 5 volt DC between studs
A1 and A3 and between studs E1 and E3 on the rear of control box.

Hi Jeff,
I had an indication problem on my 5500 many years ago
I opened the rotor and discovered that there was a cold solder joint
on of the pot contacts...a proper solder joint solved the
problem...an easy one to check first..

As I recall, there are reports about meters quitting/acting up because
of poor electrical connections with the screws that physically mount
(and electrically connect) the meters to the case/housing. (maybe a
grounding issue? I forget specifics...)

Bill,
Start by checking the connections in the shack at the controller. If they
are good, then disconnect lines 1, 2, and 3 on the elevation side and check
the _cables_ with an ohm meter. You should read 500 ohms between 1 and 3,
and something intermediate between 1 and 2, and between 2 and 3.

Hey, I called Yaseu to order the pots and have 6 coming. Why so many
you ask? I was going to order a few of the pots for the rotor as well
while I was at it and found out they no longer stock them. If you have
a 5400 I would call Yaesu and get some of the control box pots while
they are still avail
