[Elecraft] Using the K3s Tune button causes a growing SWR on my KPA500

The main reason I abandoned small transmitting loops was their susceptibility to temperature variation, one cause being power input, the other due to instantaneous change when the sun comes out.  

Apologies for sliding off topic.
