Radio Interface Box
A home brew universal RIB Box
This is an ongoing project. I needed a RIB to program some Motorola Maxtracs for a club project. I also need to program some Yaesu radios. Instead of building a box for each radio I decided what I needed was a universal box. This is what I have come up with at this point. I found a web site with a wonderful programer that did most of what I wanted here. (Local Copy) I also found some info on the Motorola RIB box on the Bat Labs Web site. My box is a combination of both of these, plus a few little additions.
I need to consolidate all my notes and schematics, and will document them here at a later date.

Some of the things I wanted to include in my RIB
Use a DB-25 connector just like that Motorola Rib. This will allow the use of the Motorola cables with my box.
The DB-25's large hood also allows room in the cable for components that are specific to a particular radio.
Use an small external power supply to provide +12 and +5 and -5 volts
Currently I have it set up to program the following radios in the shack.
Yaesu VX-6R
Radio Shack Pro-97
Motorola Maxtrac
Vertex FTL UHF Mobile
