[Elecraft] K3 + MicroHam MicroKeyer + Heil Proset

[Tom]

I have this set up and am using the MicroKeyer cable set that has the
mic input on the back of the rig.  I have the Proset plugged into the
RJ45 adapter that plugs into the back of the MicroKeyer and provides
the 8 pin mic connector.  I have the correct Heil  to K3 adapter
cable.  I have a push to talk button that is plugged into the Heil
adapter.  The problem is that when I push the button the radio does
not key.

Other modes (CW, RTTY, etc) key the rig ok.

Any ideas?
