Hi Mick,

Perhaps D19 has simply failed.  If shorted, it will attempt to pull your 12
vdc supply voltage low and thus affect other rig functions

 I would just snip D19 out for the time being.  It provides some protection
for the final PA transistor when transmitting without an antenna, but
otherwise does nothing.  See if that doesn't restore full K1 operation, and
then make sure you don't transmit without an antenna with D19 removed.

You'll want to eventually replace D19, but if you have easy local parts
access where you are in the UK, almost any 36v Zener should serve as well.

Let us know how it turns out.
