KAT500 tuning

[Elecraft mailing list]

I run a full K-Line - K3, P3, KPA500 and KAT500, and I have a bit of an  
issue with the procedure for tuning the KAT500 with the KAT500 in Operate.  
Here is the situation:
 
With the KPA500 in Standby, I tune the KAT500 by first pushing the Tune  
button on the K3 to apply 20w of drive, and then follow by pushing the  Tune
button on the KAT500.  Once the KAT500 has tuned, I then inactivate  the
drive from the K3 and switch the KPA500 into Operate.  No problem  at all with
this.
 
Occasionally when operating with the KPA500, I need to retune the  KAT500.  
So, I must switch the KPA into Standby, and the retune the  KAT.  
 
Here is what I would like:  With the KPA in Operate, hit the K3's Tune  
button and have the KPA "automatically" go into Stadby so the KAT  can be
tuned.  And, then, following the tune cycle, have the KPA  automatically revert
back to Operate once the K3's tuning has been  inactivated.  
 
Is there a procedure for this, or could a macro be built to do  this?  Or
could this be incorporated into a firmware upgrade?
 
I'd be interested in knowing if automating the Operate/Standby  function of
the KPA500 has been discussed previously

Ummmm ... maybe I misunderstand you, or you know something I don't know,
but why do you switch the KPA500 to standby before initiating a tune
cycle on the KAT500?  I set the K3 tune power such that I get 25 W from
the KPA500, and tune with the KPA in Operate all the time.  My KAT500
seems to like about 25 W, 20 W is kind of right on the edge.

I "trained" my KAT500 when everything was dry, and I run in MAN, so it
just recalls the settings when I QSY.  This works for the tribander and
a GAP Titan vertical.  My low band sloping V has a matching section made
from window line which is affected when it is wet, so I need to retune.
  I just tap TUNE on the KAT, hold TUNE on the K3, let it tune, and then
tap TUNE again on the K3.

IIRC:

I don't have a K3, but do have the KAT and KPA.  Mine drops the amp when tuning
and brings it back when done.  I don't know the ins and outs of using the
combination with the Elecraft XCVR.  I use a TS-590S with the amp keying running
through the tuner as instructed.
