[Elecraft] P3 TX MON envelope display

[GRANT YOUNGMAN]

The envelope display is not a “snapshot”, but it isn’t quite real time either.  Close, but if you’re used to using a scope for monitoring, you won’t call it “live”.  Also, the vertical height of the display is always normalized to the peak RF signal and there are no sweep width/rate adjustments.

I have not experimented with the CW display modes to see how useful they are.

My opinion is that the P3 envelope display isn’t a match for a scope, and probably wasn’t intended to be.  I do like having the SWR/PWR indication on the P3 display, though.
