Hi all,

I have built a number of interface boards for my K3's that some of you may
be interested in. Since a K3 only has one PTT output, I have built an
interface board that takes the LP Keyout, DIGOUT0 and DIGOUT1 and generates
a separate PTT output for HF, 6m and non-Elecraft transverters that use the
low power outputs from the KXV3. It also provided a switched 12v to control
the 6m preamp since DIGOUT1 is used on this board. The board contains 6 RCA
jacks, one is 12v in from the 12v jack on the K3 rear panel and another RCA
is provided with 12v out. There is a switched 12v jack that is activated on
6m for the remote preamp and then the 3 PTT output for HF, 6m and VHF
transverters.

This is not in competition with the KRC2 which does band decode and lots of
other cool stuff, this is a quick and easy way to control amps and
transverters. It is NOT for folks running QSK as the relays are typically
35ms switching. I will have some pictures up on the K8GP website tonight. I
have about $30 in parts and will provide the units assembled and tested. You
will have to provide a interface cable with a DB15HD for the ACC connector
on your K3, the other end of this cable connects to this board via a push on
connector (supplied) and a suitable enclosure.

If you are interested or have questions, please reply off list directly yo
me.

73,

Terry

I have been thinking along similar lines to you Dave.
Thanks for the info.

Perhaps this little circuit (http://blog.g4ilo.com/2010/01/stripboard-magic.html) which I think was sent to me by Bill 'ZV will do the job for you.
