[Elecraft] KX2 preamp

[Dan Presley]

I was out this weekend doing the Bumblebee QRP contest (lousy conditions here in PNW!) and a couple of times I noticed that the preamp switched itself off. First time I thought I bumped the switch but it actually did it 2 more times. I was running 5W cw to a magloop carefully tuned to resonance as best I could tell. I’ve used this same setup a bunch and never had that happen before-any thoughts? Thanks.
