Uniden AMX501 Programming Interface

This page is dedicated to the Uniden AMX501 Radio Programmer. You will find photos of the different AMX501's that are out there, as well as a schematic for building your own. While there are multiple copies of the original schematic out there, it is not easy to read, even after zooming in on it. Hence, the new schematic. The AMX501 will program the following
Uniden PRC radios;

SMS815TS, SMS825TS, SMS835TS, SPS310TS, SPS320TS, SMS925TS, SMS930TS, SPS910TS, SPS920TS, SPS330TS, SMU300, SMU3000, SMH400, SMH4000, SPU48, SPU480, SPH58, SPH580, IMH4100, IMH4100 Euro, IMU3100, SPU416K, SPH516D, SMH1525DT, SMU4525KT, SVS8035TS, SPS801TS, SPS802TS, SVS8025TSE, SVS8035TSE, SPS801TSE, SPS802TSE, SMU250KT, SMH250DT, SPU554KT, SPH255DT, SPU554KTS, SMU250KTS, SPU51KT, SPH51DT, SPH155DT, SPU454KT

With the additional AMX195 adapter;
SMS301TS, SMS316TS, SMS900TS, SMS318ED.

Also programs the GE/Ericsson, ComNet, MA/Com NPC-200 vhf/uhf portables and
Standard Communications GX1510 V/U Mobiles.

Here is a pdf file to see what software you need for which radio.
I have this software and can be reached via the
UnidenLMR Yahoo Group if you have questions about it.

My Ericsson AMX501 Hybrid was made with a Ericsson KRY 101 1616/11 RIA,
that I purchased for $50, and a mic cord from a spare AMX100A mic I had
laying around. The internal board is identical to the AMX501, complete
with empty rings to solder the four connections to.
