Raj,
A simple logic circuit to detect all zeros on the 4 band data lines and
the presence of Keyout-lp would do that task easily.

Hello all,
I would like to have PTT out signal from my K3 that is ONLY activated when
the internal K144XV transverter is transmitting. I thought I might use the
KRC2 with the K7MDL mod where the 8R signal is used to generate a band specific
PTT output. The problem: where do I find an 8R or equivalent (I guess 5R will
do) signal on the exterior of the K3? Can a pin on the ACC connector be used
for this purpose?
BTW, I tried building a small interface that activates the amp PTT when a 5V
shows on the transverter output. Problem: 5V is on transverter output when K3
transmit on any band.
