Given we are talking about Beta software, I think I have located another
issue with the KAT500...
If I use any sort of fast turn around transmit/receive cycle software,
like VARA, under Winlink, or ARQ type software modem, the tuner tries to
re-tune every time a most transmit cycles, even with a good SWR on the
antenna.
My antenna has 1.5:1, and if in bypass all works fine. If in MAN, the
tuner goes into a tune cycle... Which faults the KPA500. Any suggestions?
I do not have a computer connected to the KAT500, but could connect one
if needed.
73, and thanks,

"Could you note some of the ‘fixes’ that are not noted in the release notes?"
Here is a more complete list:
* An enabled antenna is not selectable with mode BYP
* F; interrogation returns zero after CAT induced band change
* Unexpected behavior for FCCS and FCMD
* Fault code 01 when attempting to tune with low power
* Fault 2 leaves KAT500 in bypass when fault cleared
* Disabling "Tune on QSY" option does not prevent RF count re-tune if CAT
frequency is available to KAT500.
All the above are fixed in beta 2.04.
There are also changes in full tune implementation that make is less likely
that TX power foldback will result in early termination with a poor match.
FCCS, FCMD, MTM and MTA commands which did not work as documented have been
replaced by FDT. (See command reference for details)
For anyone using CAT control, the biggest change is that the CAT provided TX
frequency takes priority over the counter frequency and counter will no longer
cause a re-tune at start of, or during, TX.
(All the above are based on my notes and the Elecraft release notes should be
taken as the official version of the changes.)
