[Elecraft] K3 - SWR Fold-back

[AJSOENKE at aol.com]

I don't know if this will help, but I've had two experiences with my K3 
regarding power reduction. While attempting to participate in the 160M contest, I 
connected to my 80M dipole and hit tune in the ATU active mode. I immediately 
got a high SWR and retune cycle which reduced the SWR at the rig to ~ 10:1. 
Checking the power output, which had been set at 106W, it was indicating 79W.  
During a second subsequent tune (same ant and same settings ) the rig initiated 
a tune cycle and immediately shut down. No overpower/high current indication. 
I turned the rig on again, and everything was the same as before.  I suspect 
maybe the tune was marginal and that at that SWR the rig is between a 'continue 
or shutdown' logic process. No residual effects were noted.
