[TowerTalk] Yaesu GX-800 trouble...

[K0FF]

The pot on the 800 uses all three wires, whereas some of the other models
use only the slider and one arm.
On the G-800 schematic it shows the high side of the pot goes to pin one.
Slider to pin two. Low side of pot to pin 3. The pot is a 500 Ohm linear,
but close enough will be OK for a test. If no pot is available, a couple of
fixed resistors will work.

NOTE:
I have the schematics for G-450, G-800 / G1000 in the Yaesu line, most of
the Bell type CDE/Hygain stuff, and most of the Orion versions. Any other
scans of rotor and control box schematics would be welcome for my files.,
Thanks, Geo>K0FF
