So what your seeing here is a complete bi-directional APRS messaging station in a box.
Recently, I took part in a mock disaster exercise where APRS was used extensively for communication.
One of the topics discussed was how it would be desirable for the hams on the ground to have a compact aprs message capable station with them to communicate with the EOC.
That got me to thinking, and being I had some extra APRS parts not being used, I soon came up with some ideas to run with.
I thought maybe with the right case, I could make up a compact APRS messanging station that could be taken anywhere.
Off and on I kept looking for the right case, and I found the one you see here at my local sporting goods outlet, in the form of a foam-lined hand-gun case that measures 2 3/4" X 8" X 14"
The complete station is made up of a Byonics TT4 with the companion display, Byonics GPS5 receiver, compact Adesso PS2 keyboard, Baofeng UV-3R+ with a roll-up antenna, an extra battery, and a small 12 volt gel-cell for powering the Byonics devices.
I am very pleased with how it worked out, and not only can I make changes to my ABWX via APRS messaging, but if I wish to get in to the network with this station, but cannot reach a Digipeater due to the limited power of the Baofeng UV-3R, its as simple as sending a message to my ABWX commanding the digi on, and then my beacon is digipeated by my ABWX mobile weather station.

Note....Although I have choices as for the antennas that I can use with my APRS-In-A-Box station, my favorite for good reception when set up in a fringe area is the roll-up antenna seen here.....
