K2?KAT2 mod idea

[Ken Bessler]

I'd like to get opinions from the group on this idea:

My K2 has the KAT2 which means the original antenna jack is covered up and
not used. I hate
waste so I've been thinking how I could use it. Couldn't I install a SPDT
switch or relay so I could
select either the original jack without the tuner or select the KAT2 with
it's two jacks?

Of course what would be ideal would be a firmware mod so instead of ant 1/2,
you get 1/2/3 and
have a relay going between ant 2 and the original jack.

Comments welcome.....

Ken,

Don't do that - leave the original jack covered and just forget that it is
there.  If you use it with the KAT2 installed, the K2 will not properly
control power output (it knows the KAT2 is installed and will be looking for
the power output level to come from the wattmeter in the KAT2).  There may
also be other problems such as impedance concerns since the KAT2 input is
connected in parallel with whatever you might connect to that jack.  The
boot is on there for a reason, if you defeat its purpose, 'all bets are
off'.

      I considered decoding the xverter select lines for this ... and
modding the KAT2 to not override the RF sense, that way you could map a
transverter band to the port.  After switching to XV series transverters,
tho, I don't really have a reason.
