So, this KDK transceiver I have had kicking around for a while is going to become my new packet radio, if all goes well. I'm having a bit of problems finding the pinout for the "sel-call" phone-patch port on the back. its the 5 pin DIN on the back that is going to become my KPC3+ Data Port!
I figured I'd ask around before I went through the trouble of getting a meter out.

thanks!
