Power up TS-830 first, then the VFO-230. Both external and internal displays jump to 14.000 (0.0 on external VFO). When I spin the encoder, the frequency increases (not smooth, jumps and hesitates) REGARDLESS of which direction encoder is turned. The rig's VFO and external VFO are tracking ok. Removed the encoder assembly from the 230, checked and cleaned. All connectors on PCB cleaned and re-seated. First time seeing this problem.
