I did not say that you can’t train in manual mode. I said AUTO should only be
used for training - not for normal operation.
I really hope that your one button push takes account of other users on the
band when you’re training. Presumably it has some very sophisticated detection
that can tell

No, it's code in an Arduino Mega 256 than sequences a couple of state machines.
One state machine controls putting KAT500 in full search tune, powering the
exciter, waiting for completion of auto tune, returning exciter to RX mode.

What button is that, Andy? I set up a spreadsheet that shows the

VFO by the correct delta, but I still need to tap the

Training a KAT500 does not require it to be in AUTO mode. I NEVER put my

Jeff,
One thing I forgot. The KAT500 should only be in AUTO mode when you’re actually
training it. i.e. You tune the radio to a frequency, then TX (in TUNE mode) and
wait for the KAT500 to stop clicking. ISTR that when a solution is found, the
KAT500 TUNE light goes off and the solution is
"AFAICR the manual says that if an AUX cable is connected between the KAT500
and the radio, the KAT500 will follow any frequency/band change and if a tuning
solution has already been stored for that frequency/band it will be employed
before the radio goes into TX. In other words, whilst the
KPA inhibit SWR? The KPA500 uses Reflected Power for all of its protections
except for one item - if the SWR is above 18:1, it will throw an immediate
fault.
There is no adjustment for these thresholds. As far as the Auxbus, the KPA does
not listen but only talks on it, conveying band, mode and
Thanks. That's good detail. I'll recheck the manual once more. I made a
common mistake of assuming too much and not reading enough. I have tremendous
respect and faith in the engineering put into the system of the Elecraft line..
That's a long way of saying, It works brilliantly.
