[amsat-bb] Using Yaesu VX-3R on the FM Birds

Just picked up a VX-3R to build a Microsat portable station. Reading the specs, it appears I should have any problems programming it for the birds but have been told that I have to "mod" the radio to get it accept all the sat frequencies. Has anyone used the VX-3R and did you need to do the radio mod and if so, which one ?
