Problem with K3 and KPA on 6 meters

Richard Lawn

I tried to use the amp on 6 meters the other day and discovered a strange problem. I was using WSJTx on a digital mode and wanted the run about 200 watts. For some reason the K3 wasn’t activating the amp unless I tweaked the power pot on the K3 just a little bit and then suddenly the amp would activate. I did not notice the problem on other lower bands.

Any thoughts?
