Actually what Mike says is correct, but I believe you stated that you had
the "Kenwood interface", without knowing if you mean the IF-10B  or the
IF-232 I don't know what you need. If you have the IF-10B installed in the
radio, you need the IF-232 or equivalent (there are several suppliers or
you can roll your own). If what you have is the IF-232 you need to find a
used IF-10B or just buy the Piexx board and forget about the IF-232 (it
isn't needed with the Piexx board). If you are an extremely lucky guy and
have them both you just need to hookup & configure. Personally I could
never understand why the rig manufacturers didn't just put and RS232 port
on the back of the rigs like the newer Kenwoods. If they wanted to be
current now, they would incorporate a USB or firewire port!

Good luck.
