[Elecraft] K3/P3 - To watch own TX, what lines need to be disconnected?

[Bill Conkling]

For those who want to use the P3 to adjust TX EQ, what lines need to be
disconnected from the RS-232 circuit.  Should be easy to make a box with a
switch to disable certain lines without having to disconnect the cable
between the P3/K3.

 

Maybe could be triggered by the "Key Out" signal, or just a simple toggle
switch.  

 

Better still, add it to the P3, or offer it as a 'fungtion key'".
