KAT500 Utility problem

[Kidder, George]

Hi gang,

I hope this is a minor problem, but I cannot seem to solve it.  I have a
K3 running 5.53 firmware, and a recently acquired KAT500. They are
connected as in Figure 2 of the KAT500 manual, using the KPAK3AUX cable
with the key line interrupter, and a separate key line to activate my
AL-80A amplifier.  Everything seems to work "just as per" with the
exception of the frequency tracking function on receive.  This was
running at one time; I did a tune every time the K3 crossed a frequency
boundary, and it seemed to track thereafter.  Now it won't track - no
relay noise from one end of the band to the other.  It seems to remember
specific settings, and will re-tune on transmit, but does not re-tune on
VFO movement.  (No split freq, either.)  There is no KAT3 in the K3, so
CONFIG:KAT3 indicates "not inSt", but tap 1 toggles getween KAT500N and
KAT500Y, and was left in the latter position.

This is no big deal, but it would be handy if the KAT500 would return on
receive to the last settings for that frequency, rather than wait for a
transmit pulse.  Besides, it is supposed to do just that!

Any thoughts?

George, W3HBM

I'm running the latest ver 5.54 on my K3 and ver1.75 on my KAT500 and I do hear the relays click as I tune
But you do need to pause on a frequency for them to click (they don't switch while tuning)

Dick and Steve,

Thanks so much for your comments.  The problem was indeed a cable - it
had fallen out completely!  The rig is in a tough place to get at the
back, and I never noticed.  The "interrupter" can only be fastened with
a wrench, and I had not done that, with the results noted.  Now I have
found the wrench in my tool box, and I think it will stay in place!

Harry,

You are right about the requirement to pause - now I can see that, with
the rest of the problems solved.

I guess you cannot expect information transfer through thin air!

Thanks again,

George, W3HBM
