I'm presently using all the defaults, plus AGC HLD = 0.3 (slow AGC hold

IMO, construction of open-feeder line is worth the effort. I am using an
old stash of E.F. Johnson spreader insulators, but effective balanced line
can be made by using PVC tubing, with the ends sliced

There is a time delay in the monitor, so to the person

a reverb.
Perhaps the monitor is turned up too loud and monitor audio
is getting fed back from the headphones into the microphone?

I find the antenna system loses a *lot* of its effectiveness when the
ladder line is wet. As a guess I'd say a half or more of the received
signal strength is lost (and , I suppose, similarly for transmit) when
the line is wet..
When not wet its a very effective component in my antenna system.

Perhaps Elecraft or a machinist would consider offering optional left and
right side panels for the K3 that are drilled and tapped to accept a mobile
mounting bracket. Painted to match, of course.

Sorry for an off-topic question. Does anyone have any information about the
dry vs wet characteristics of "450 ohm" ladder line? I have never used this
type of line, but I might have to use it for "mechanical" reasons to feed
another antenna now being built. I am told that its characteristics ch
