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. Al WA6VNN K3 #31 Of course it had everything to do with it - but an experiment is an experiment - I like to see what a well designed radio can really do. Besides I made a few dozen contacts on the 160M contest and they were the first contacts I've made on 160 in 46 years of hamming. I rather enjoyed it! I hope the info was helpful in answering the question about SWR and rollback. Yes it does roll back, and very gracefully I'd say.
