Wayne,
Thank you for your thoughtful positive response to the
KAT500 SWR faulting & band change issues.
My K3 (4520) has performed flawlesly since new, thank you & team at
Elecraft, however my KAT500 (0433) has exhibited some of the above
reported difficulties in operation.
On the basis of the foregoing, I would request that you include me on
the list for the updated firmware for my KAT500.
Thank you and the team at Elecraft for your wonderful support to your
loyal band of customers, myself included.
May I wish you& all at Elecraft all the best for 2014,. May it be
healthy, happy & successful to all at Elecraft.
73, Eric VK3AX.

Hi all,
Yesterday we analyzing the reports of unexpected SWR faults and band changes.
They fall into a few categories, and we have a good handle on how to deal with
all of them in firmware. (Faults caused by antenna/feedline/connector problems
are the only exception. These can cause SWR to change asynchronously, and
there's no way to fix this in firmware. The amp and tuner are correctly going
into bypass mode, retuning, or inserting attenuation in such cases.)
Unfortunately the KAT500 changes cannot be completed immediately because the
responsible engineer is leaving for a week's vacation starting tomorrow. But
the changes are fairly simple, so shortly after he returns we'll be sending out
new firmware to a group of customers who have reported problems. Sorry for the
delay.
In addition to firmware changes needed to handle SWR and band-change issues,
we'll be improving integration between the KAT500 and the K3. For example,
you'll be able to use the K3's ANT switch to select antennas at the KAT500.
We're also working on a K-Line Installation guide, intended to be a more
convenient resource for all of the information needed to interconnect and setup
the K3, P3, KPA500 and KAT500. We hope to have this out a month or so after all
of the pending firmware changes have been completed.
73 (& Happy New Year)
