[Elecraft] KAT500 operation?

[Mike Hagele AC6JA via Elecraft]

I am using the most current firmware versions in the K3, KAT500, and  
KPA500.
I am also using the Elecraft auxilliary cables.
Not sure what else to check as to why the KAT500 won't update the tuner  
preselects when QSY'ing?

Mike,
Not normal! The KAT should QSY if the KAT500 is interfaced  with the K3 & 
KPA500 as per the manual. It is trule a K=Line  system!

First - make sure you have the most current version of  firmware. There 
have 
been a few updates that fixed issues that you  describe. I have Beta 1.63 
in 
my KAT500.

You need the K3, KAT,  & KPA all tied together as per the KAT manual. I may 
not have the same  manual as you do but it is the section interfacing K3 & 
KPA with DB15  cables.
Make sure that the antenna selection for each band is correct using  the 
KAT500 Utility.
Set the tune power in the K3 - I use 20 watts;  because I had an early KAT 
and that was what it needed. Not sure if it  affects the KAT but I have my 
K3 
power set to per band for the  KPA.

Then you need to train (tune) the KAT on the band segments that  you will 
be 
QSYing to. The bands have different segment sizes so check the  manual. I 
tune with the KAT in Auto mode. Press the KAT Tune button then  hold the K3 
Tune button. This should initiate the tune function in the  KAT500.
I "Trained" my KAT on all bands that I use. I incremented the  frequency 
from 
the bottom of the voice frequencies to the top frequencies.  This did take 
a 
while but now I can QSY and a second or so after I stop  turning the VFO 
dial 
I hear the relays in the KAT set. This means that the  tuner is optimized 
when I transmit. BTW - I do run my tuner in MAN  (manual) mode so it does 
not 
try to retune on voice  modulation.

Above is how I operate my KAT. I have an early Kit that has  had several 
firmware updates. A couple were for the issue you seem to  have.
Mine works well for me with several antennas.

Hope this might  help you. If not others may have an idea of Elecraft will 
surly help on  Monday.

I am using a K3 and KPA500 with the KAT500.
I also have  the KAT500 mode set to MAN.
I thought that the firmware was supposed to  switch the tuner automatically
when you switch bands?
After I go to a  new band, I need to tap my key  momentarily to get the
tuner to tune  to the new frequency.
Is this  normal?
Let me know as I thought the  tuner would remember the presets when  QSY'ing
to a new  frequency?
Any help would be appreciated.
Thanks.
