[TowerTalk] Yaesu Rotors

[Edward Sawyer]

Thanks Grant.  This looks like a project looming for me may this winter.  I
have a few of these rotor units and would love to get one good 2800 out of
them as a spare.  I will let the group know how it turns out.

The basic control/indicate design is the same in all, as far as I can tell.
A 500 ohm pot inside the rotator and a servo in the controller that nulls an
inside pot to match (not sure the value). The schematics and pcb
implementation inside the controller is a witches brew mess, and the gear
train + o-ring belt drive a total PITA to replace the o-ring pointer "drive
belt".

Shortly I will connect a 2800SDX control to a G1000 rotator as the G1000SDX
controller is flakey.  Then one more cross over will be tested.  If not,
then both controllers get pitched for a Green Heron.

My G1000SDA control works fine with a G1000SDX rotator, but having had the
rotator apart I think all G1000 rotators are identical. Might also be true
for the 2800 series.

Motors, gears and bearing arrangements are different among the rotator
families AFAIK.  Limit switches look to be stock micro-switch variants.

I replace the bizarre keyed Jones type receptacle on the 2800 series
controls with a stock Jones 300 6 pin from Mouser. $5.
