[Elecraft] KAT500 problem

[Geoffrey Downs]

In the KAT500 manual it says the the K3 will not initialise properly unless 
power is applied to the KAT500 before switching on the K3. Maybe this is 
what happened if, say, you left a DB15 cable from the KAT500 connected to 
the K3 when you connected coax directly from the K3 to the KPA500.

73 and good luck

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
