1) What is this diagram trying to say?
Does the D710 head have a 6-pin Mini-DIN connector on it? Or is it the
RJ-45 plug? (The Mini-DIN pinout looks like the standard used on many
Kenwood/Icom/Yaesu radios with the mini-DIN "packet/data" connector on
Does this mean a standard mini-DIn-6 to mini-Din-6 KVM cable will
connect the radio TX/RX/DCD/PTT signals (but not DC power) to the head ?
2) I thought you had moved all the APRS stuff off the USNA server......
