Introduction
Photograph of NT-MP series radio transceiver
Ultra compact, while offering the ETS300-086 compatible performance and the features all you require. Indeed fully CPU controlled wide-band design, high speed synthesizer, Scans of various modes. Programmable CTCSS is standard feature. Programming via PC for all parameters and cloning capability through the microphone connector. Highly versatile in the utmost compact housing.

Simple and Easy Operation
Two large channel selection Up/Down buttons are laid Out at the center and the four click touch function selectors with back light for night use. Dots in channel window blink during scan modes.



Your System Integration
The TRX part and the Logic part are completely segregated by design which will enhance your own logic designs and local contents. The TRX board provides the ready I/O ports for various interfaces including one for FFSK modems for trunking logic or other custom applications of your own. The radios without our original Logic board are available in all bands.
