[Kenwood] Kenwood TS850S auto tuning problem on 40 and 80

Try it into a dummy load.  It will ensure the problem is the radio.

When in the Auto mode and the tuner turned on, the motors rotate, the swr meter pegs out on the high side, and the motors just keep turning. To complicate matters the problem is periodic and independent of the transceiver being cold or warm. Nor does it make any difference whether the carrier control is turned fully clockwise or not. I have visually checked the auto tuner board for bad soldiering and checked all screws. So far of no avail.
