SSB/CW on 6, 2, and 3cm, but FM only on 70cm this time.

Started experiencing a problem with the backup K3 which I was using for 6.  It appears to have developed a known problem with its 100W PA DC power feed and is limited to 10 watts on transmit.  It worked just fine at the beginning of December during our trip to PJ7 but was just placed into home service whilst the main K3S is at Elecraft for general tune-up and sporadic problem.

I believe I have a temporary solution to bypass the failed PA stage and use my otherwise idle KX3 external amplifier with the K3 until the K3S gets back from California.
