JR XP8103

The 8103 is JR's successor to the 388. It offers several new features - most importantly a new large size screen for easier programming. A graphical interface makes it quicker to program than its predecessors. The 8103 maintains all of the features you would like to see in a full-house computer radio. It has eight channels, 10 model memory, PCM and FM, and all of the traditional features including sailplane programming and six types of programmable mixing.

There are 2 models of the JR 8103. The main difference is that newer versions have digital trim.
