[Elecraft] P3TXMON Bug?

[Alan]

It actually does go back to split screen spectrum/waterfall in receive 
mode.  In transmit mode the spectrum display is replaced by the 
modulation waveform, but the waterfall remains on the screen.

There are two reasons why the "meters" remain on the screen in receive 
mode.  One is that it would be pretty annoying when sending CW QSK for 
example to have the window jumping up and down every time you key.  The 
other is that it would require re-drawing the waterfall every time you 
go to transmit mode, which would lose all the waterfall data.  I think 
many people like to be able to look at the waterfall while transmitting 
to see where the signals were the last time they were receiving.
