So how would you like to use your Psion Revo for APRS Messaging
when out 'n' about ??? Well it can be done...
I have yet to find a basic APRS Messaging program especially written
for the Psion Revo, so I am going to explain how to "cheat" ;-)
The minimal hardware you will need is:-
1) Psion Revo - I use the Revo Plus 16MB
2) Revo Docking Station - You'll need a serial-port
3) TH-D7E Handheld - Built-in KISS TNC (nice)
4) GPS to plot your position - Optional, not needed for messaging
HERE COMES THE SCIENCE BIT, CONCENTRATE...
Software-wise, you'll need to install the XTM DOS Emulator which will
allow you to run BASIC MS-DOS programs on your Revo. All you need is an
MS-DOS boot-disk which is copied onto the Revo and executed from the
"EXTRAS" button on the screen.
You can use PsiWin to copy all your DOS Apps over to the C:\ of the Revo
and run virtually any DOS program you wish. Tried and tested with:
BPQ (SWITCH.EXE), EDIT.COM, X-ROUTER (that's what we are going to use).
X-Router is an AX25 + TCP/IP Routing software which has basic APRS
Messaging built into it. This allows you to run a KISS TNC (TH-D7E)
from the Revo and use it for Messaging whilst on the move.
Once you've got your XTM Emulator going, assigned a Serial Port to it
and put X-Router on the Revo, you can connect it up to the Kenwood radio.
I'll leave it up to you how you attached it, but cutting off the long
cable from the Docking Station is probably a wise-move.
The only real problem (unless mounted in a car) is the Revo is prone
to falling off the Docking Station, so unless you want to velcro it on
you'll have to watch how you handle it!
This was just a basic outline of how it's done. If you want more info
on any particular part of this project, I shall gladly send out a bulletin
covering it in more detail...
If you are REALLY into gadgets, then have a look at:-

Using a "kiddies toy", you can do virtually the same as what I've
described but using software designed for the unit. The main problem
is the horrible colour of these "toys", but there is a local station
on UI-View here and he says they are rather good...
They also have built-in 900MHz transceivers (legal?) which means that
you could run the software as a DIGI and the whole neighbourhood could
be running APRS in no time! What fun.
Happy experimenting...
