- OK, I've got this TNC-X sitting here -- I bought it last June and
haven't put it on the air yet. Now I think I'm ready -- in the truck I
drive, I use a HamHUD and a KPC-3+ and the KPC-3+ just loses its
settings too often. When it does, it goes back to NEWUSER mode and the
current HamHUD firmware is KISS-only, so I have no way to get APRS going
again until I'm at home.
So how do I do this? I need to speak 4800 BPS from the HamHUD to
the TNC, which the instructions seem to indicate is easy. My current
setup has the KPC-3+ modified to output power on the DB-25 to power the
HamHUD and GPS -- so I guess some patch cables would be the easiest way
to get the TNC-X going. Need to go from the DB-9 on the TNC-X to a
DB-25 so I can imitate the current KPC-3+ cabling -- and some kind of
adapter cables to connect to the radio as the KPC-3+ does.
BTW, the radio is a GE Delta -- anything special I should know
about using the TNC-X with the Delta?

are audio levels.
The TNC-X docs outline a simple way to get them to very acceptable
settings by listening on another radio while you adjust the two
potentiometers in the TNC-X. I have built three of the TNC-X units and
find that if you start with both pots mid-range it will send and
receive and you can just tweak them in from there.
