[Elecraft] ALC and the K3

[Josh]

The problem I've had in the past using ALC in that manner is that it was transparent to me that ALC was limiting output power. So unless I happened to notice, or someone local pointed out my wicked key clicks, I was unaware. Using TX inhibit, I get the same result of protecting the amp, but it happens in a more spectacular way with red fault indicators so I know the operator messed up. Not sure if ALC will shut down the exciter as well as TX inh if there's a jumper, feedline, tuner or antenna problem.
