I just got a second hand KPC-3 and I'm trying to connect it to a Kenwood
TMV7A using the interface data cable, the PG-5 , I found some connection
diagrams over the internet, and I have the manual, but I don't have the
starting guide or something, and so I did the connections using the DB9 port
SETTING UP KENWOOD TM-V7A FOR PACKET/APRS USE

1. PUT 144.39 ON THE LEFT SIDE. (USA APRS frequency)
2. PUT FAVORITE REPEATER ON THE RIGHT SIDE.
3. PRESS "MNU" AND CLICK TO ITEM 15 "DATA TRANSFER".
4. PRESS THE "V" AND CLICK TO '.2' "DATA BAND".
5. PRESS "SET" AND TURN IT "ON".
6. PRESS "MNU". YOU WILL SEE THE WORD "DATA" OVER THE LEFT
(144.39) AND "PTT" OVER THE RIGHT.

TO DO VHF/VHF OR 2METER VOICE REPEATER AND PACKET AT THE SAME TIME:
1. PRESS THE RIGHT BAND SELECT BUTTON.
2. PRESS 'F' + [CONT.SEL.] (LITTLE BUTTON BETWEEN VOL CONTROLS).
3. MAKE SURE 'PM AUTO STORE' IS ON SO YOU DONT LOSE ALL SETTINGS
WHEN YOU TURN OFF THE RADIO. (SEE PAGE 39 OF THE MANUAL).

In the 'old days' they called us hoods,
because we wore our faces like shrouds,
and never spoke.
