[Elecraft] P3 Feature Request - Transmit sampling

[Don Wilhelm]

Mel,

Not a 'glitch'.

That is a hardware "artifact".  The transmit signal you see is going 
through the 8 MHz IF which is being sampled by the P3.

So yes, you see your transmitted signal, but before it gets to the mixer 
and on-frequency RF stages.

It should still be useful for seeing that your audio levels and the 
modulation is OK, but it will not show you if the final RF output is 
still OK.  If all is working OK in the K3 (RF wise), then that is a good 
indication, but should the RF stages go non-linear (or other condition) 
because of some fault, that will not be seen on the P3.

73,
Don W3FPR

If it is a glitch, it must be a SW one because the display hardware is doing its job.  Then one would suggest it could be toggled on and off????  What a wonderful thought.... hint hint.....
