I have yet to go that. But, I believe that "homing" the autotune system is required. Manual homing can be done via a crank tool on the access port. Carefully.... very carefully. I think I may have a motor, if that is the issue.

Subject: [MRCA] ART13 bypassing autotune circuit

folks. another ART13 Ive been working on has a bad autotune motor . Drawing about 15 amps, no filaments lit and some smoke coming from the motor. I killed the power right away. Has anyone bypassed the autotune circuit to make the set work without needing the autotune circuitry? thanks Jeff N2IA
