[Elecraft] KPA500 Problems Update

[Mike VE3YF]

First I would like to thank everyone for their support, suggestions 
and comments. Without that kind of help, I would still scratching my head.

Here is where I stand:

I have a work around by using the KPAK3AUX Cable from K3--> KAT500 
-->KPA500 with the Key line inhibitor installed at the K3. I am also 
running a separate key
line from the K3 Keyout jack to the KPA500 PA Key jack. (My first 
keyline cable had a broken shield, so I have replaced it)

Everything seems to work this way, however still have the problem of 
either the KPAK3AUX cable which does check out ok, Pin 10 is straight 
thru, while pins 1,6,7,
and 8 are not hooked up in the cable, verified with multimeter.

The other possibility is that PTT Line of either the K3 or the KPA500 
AUX Port is not working properly. I just have to figure out which end 
is at fault. I have tested
Pin 10 at the K3 and when I key the rig  I see movement on the 
multimeter , so I am thinking that Pin 10 at the K3 end is working 
ok. However I have been wrong before.

I have tried 2 x KPAK3AUX Cables and get the same results with both 
cables so I think I can rule out a cable problem

That really just leaves the KPA500 AUX port Pin 10 and inside the amp.

I think I have pretty much covered all the area's of concern so I am 
going to do up a detailed report of what is the fault and what was 
done to verify things etc and talk
to Elecraft on Monday.

Tnx for all your help.
