[Elecraft] P3 TX Mon question

[W4CCS]

Guy:

I agree and hold out hope Elecraft will do something.. If the sensitivity is
set low for QRP operators, seems they would not need the 2KW sensor.

Maybe have an option in the setup.. Like I stated earlier, it is very
annoying and quite sure I'm not the only one with this concern..

It would appear that the display needs an option to gate the display with
the equivent of local TX asserted so it only responds to its own transmitted
signal.  An option because others might want to know that their TX signal
was coming back at them on another coax.

Or perhaps set an adjustable gating power level defaulted to one watt.
