Re: [Elecraft] KBPF3 and KPA500
Received 3 HD15 M/F gender changers, pulled pin 11 out, attached it the end of the KPA500 control cable, and now the KBPF3 and KPA500 work perfect! Should now be able to use a receive only antenna on 80. My vertical is OK, but it can be noisy. 73 DE K8CXM ...

Re: [Elecraft] KBPF3 and KPA500
As I understand it, the way the PR6 uses the DIGOUT1 connection (pin 11) and the way the KPA500 uses the same connection are physically incompatible with one another. The solution is apparently to break the connection on pin 11 to the KPA500 - see http://elecraft.365791.n2.nabble.com/KPA500-PR6-AUX-Cable-Pin-11-td7558085.html . I believe that if you wanted to use the KPA500's INHIB IN feature, you would have to connect the K3's pin 11 to the KPA500, install jumper P2 in the PR6 and disconnect the control connection from the PR6 to pin 11, thus disabling its automatic bypass feature. 73, Rich VE3KI K8CXM wrote: I installed a KBPF3 option, and it works OK, mostly.

Re: [Elecraft] KBPF3 and KPA500
Hi Jim,
This has been mentioned a couple of times with some good trouble shooting by
somebody last month (I didn't save the email and couldn't track it down in the
searchable archives).
What he found was there is a connection in the KAT500 that was pulling the
DIGOUT1 signal low and keeping the PR6 turned on all the time. A couple of fix
suggestions were made including removing R63 in the KAT500 or clipping pin-11
in the TX Keying line interrupter (if you are using it). You could also get
another DE15HD gender changer and clip pin-11 in it and still maintain the amp
keying line in the KPAK3AUX cable. Or you can just activate the PR6 when you
want to by supplying it 12V power.
You may want to contact Elecraft Customer Service about the advisability of
removing R63 or other solutions they may have found.
Cheers,
