RM4 — HF Data Modem & ALE Controller

Posted on February 8, 2016

RM4 is a high data rate HF modem and 2G ALE controller for standards-based naval and military long distance and point-to-point data communications. 

The RM4 is capable of maximum data rate of 9600 bps over a standard 3 kHz (SSB) HF radio channel and is designed to operate in conjunction with an external STANAG 5066 ARQ server, such as the RC50 Email Communications Suite. The function of the RM4 is determined by the selection of a modem software pack loadset.

The unit is intended for installation into 19” rack systems or to be used as a desktop unit. Front panel status LEDs show the current modem status.
