K3 VCO CAL S/N 906

[Bob DeHaney]

I am trying to perform the initial VCO CAL.  When I exit with MENU, the
calibration starts, runs rapidly up to 127, and then halts with VCO Error
00005.  Any suggestions?  I have sent an email to K3 support, but they are
sometimes off on Sunday too ;-)

I am beginning to wonder if my K3 Rear panel PTT in RCA jack has a
problem. It appears totally dead - I can't get it to switch the radio
to tx. Also, it has no voltage across it that I can pull down by
shorting the pins

I must have some configuration option screwed up, but have tried
several changes to no avail.

My front mic socket PTT works, as does both the radio PTT command on
the CAT and the RTS line when I set that option.

What am I doing wrong? How can I prove to myself that this jack is OK?

I have learned that I should have 4.9V present on that line, and I
don't, so it must be a hardware problem. I will try to fix it next
time I open the radio up.

This list is great to solve problems lilke this. Thanks guys.
