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

[Alan Bloom]

The RS-232 cable between the P3 and the K3.  You could make a box with a
DPST switch or relay to open the TXD and RXD lines if you don't want to
unplug the cable.  On the other hand, how often do you adjust TX EQ?  It
would probably be easier just to unplug the cable than to build a switch
box.
