Bob,
I have a 5400 but have had the same problem. We used to buy them from
Yaesu at a premium. In defense of Yaesu they are not in the parts business...
The good news is! - My experience is they can almost always be
repaired! There is a little wire running to the center of
Hi Bob, W7LRD
Befor tearing everyting apart and guess that the problem is the pot in the
rotor get a DC voltmeter and measure the voltage between E2 and E3 on the
rear of control box.If the pot is OK you must measure a variation betweeen 0
volt to about 6 volt DC turning the elevation all the way
Isn't the G500 the equivalent to the G5500 elevation rotor? Mounted right
side up. Isn't the G450 is the azimuth replacement? I have used these in
the past but don't remember if they have threaded holes for the bracket.

I have indeed used the G500 to replace the elevation rotor. It was swap and
play...

Bob,
You can find heating tapes for pipes at most hardware stores. You can wind
them on pipes to keep them from freezing. I have also seen adhesive pads
for similar tasks at technical specialty stores. Over the years I have
known a couple of hams in the northern areas who use them to keep
Even though we don't get real weather down here in SoCal, Bob, I put a
small plastic trash can over mine.
I found one large enough to fit over the elevation rotor, and cut some
holes in it that lined up with the cross-boom. Then I made some slots
from the holes down to the edge of the trash
Bob
Liquid gasket pro seal would probably do the trick.

I got a flat-sided plastic dustbin deep enough to shield both AZ and EL
rotors, when placed upside down over them. Two holes were cut and the
cross-boom fed through. It is not enough to keep the rotors completely
dry, but sufficient to keep 98% of the lashing, tropical deluge off.

Is your drainage hole plugged?
I'm sure going to check mine now.

Hi Bob,
Not sure I can help--but I wonder what interface you're using between SatPC32
and the G-5500?

Bob
Which rotator controller are you using with your 5500 ?
Did you configure your Rotator to be 450deg in SATPC32 ?
Some controllers like EA4TX have the smarts to utilize 450 deg even if your
software is configured for 360 For example if your rotator is sitting at 350
degs and you tell it to go
The thing that's suspicious is that 450 is the limit of rotation. I
don't know which end of the movement potentiometer that represents, but
you might have a loose position sense connection or dirty pot wiper. The
controller would think it's not where it's supposed to be, and tries to
move in
ps should have mentioned I am using the LVB tracker

Hi Dean,
Usually an elevation rotor is mounted so that the antennas are directly
horizontal (zero degrees) when the rotor is positioned at zero. Then the
satellite elevation is the same as the rotor's position. 45 degrees up is,
well, 45 degrees. Straight up is 90.
What others are
You want to mount the antenna on the elevation rotor horizontal so it
can flip over on it's back and track through the AZ mechanical stop.
For instance, if the bird is going though North/South, which ever you
have for the mechanical stop, software can control it to flip on it's
back and

I am installing a G-5500 Elevation rotor and trying to determine

If you're starting a flipped pass where the satellite AOS is at 45 degrees,
wouldn't the flipped pass start at 45+180=225?

Hi Paul, KW7Y
I suppose that you measure:

Between A6 and A5 for CW= 4.4 ohm
I suggest you to put an AC ammeter 5 Amps f.s. in series between the
common terminal A6 of the control box and the wire coming up to A6
in the motor.

If you have the LCD fitted, do both the left and right Az/El readings move
