[Elecraft] KAT500 problem

[Hunsdon Cary III]

Following up on my High SWR problems (no response from Elecraft Support on Friday to my email):
I disconnected the KAT500 and KPA500 and connected A4S feed-line directly to the K3.  It loaded beautifully and the internal tuner read 1.0-1.  Good, not the feed line or the K3…
Next I connected the KPA 500 (without the KAT500) and turned the K3 on….the display "froze" a few characters into the "welcome K4TM"  message and the power button would not turn the K3 off - I had to turn the Astron 35M off to cut power to the K3.  When I turned the K3 on again, I get a blank screen and must shut the power supply off to turn the K3.
I've had a Kenwood 520SE and a 570D and a TenTec Omni Vii - Drake TR-4 before all that and I know the K3 is smarter than I am but I have never encountered issues like this before!  Any ideas?
Thanks for listening and any help that is directed my way!
And I guess I won't be checking into the Elecraft net today as a result.
73,
Cary, K4TM

>>> HELP, please.
>>> 	I have the K3-100, KPA-500, and KAT-100 (factory built tuner).  I know to activate the tuner before turning the K3 on (it does make a difference).
>>> 	When I turned everything on for a schedule today, I am experiencing high SWR and the K3 shuts down…also, when I go to tune the KAT500 and tap the TUNE button, the AUTO begins to flash but when I key the mic (HEIL MD-2) with audio it clicks and clacks for awhile and SWR drops to 1.2
>>> 	When I then put the KPA-500  in operate, I get red lights for high SWR and the amp goes to STBY with the FAULT light lit and the K3 shows FAULT 9 which the manual is "excessive reflected power (high SWR).  Well, the KAT500 says otherwise and I am at a loss to figure it out.
>>>        My antenna is a Cushcraft A4S with 110 feet of high quality RG-8 and everything was working just fine a week or so ago.
>>>        Last Sunday, I did turn the K3 on and my Vibroplex keyer was connected.  I came in about 30" later and noticed an ERROR message: ERR KEY  Apparently the Viproplex was keyed when I turned power on and I have disconnected it - could this have anything to do with it?
>>>       Appreciate any help you can give.
