[TowerTalk] TowerTalk Digest, Repairing Yaesu G-800SA

[Terrence R. Redding Ph.D.]

Perry, thank you for your help.

I am going to get the RC1-Y-Digital-Rotor-Control, unless someone here has
had a bad experience with them.

It appears my controller is bad.  If someone has the voltage chart for the
Yaesu controller maybe I can repair it.
