INTRODUCTION

The T4000 RF module is a Tri Band transceiver assembly that operates in 136 – 174, 380 – 520, and
764-870 MHz ranges. The T4000 RF module is a modified Motorola APX 8000 Tri Band portable radio.

The outer casing, top controls, front display and keypad are removed. The RF chassis is slightly
machined but all electronic circuits are unmodified from the original APX 8000 radio.

The transceiver is designed to be installed and operated in a Technisonic Multiband Airborne Radio
TDFM 9000 platform. All external power and antenna connections are provided by the TDFM 9000 as
well as controls are via the front panel and display from the TDFM 9000.

The RF module is capable of operating on Analog FM, Wide and Narrow and Project 25 Phase 1
conventional and P25 Trunked Phase 1 and 2 systems.
