Third choice it to use it for an APRS Home Station.  It will work just fine
for that but you would need at least a Version 6 EPROM to use it for a

Kantronics quit selling upgrade EPROM'S for that unit a long time ago.  The
latest version is 8.2 so maybe you can look around and see if someone has an
"extra" one.

The difference between the 3 and 3+ was a hardware and firmware difference,
so the EPROM'S are not interchangeable between the two.  Don't know if they
had any operational differences at that time.
