High Performance HF SDR Transceiver


The RT7700H is an IP addressable, digital HF software defined radio
(SDR) which combines DSP-IF circuitry and powerful microprocessors
in a robust desktop or rack-mountable package supporting the
demands for HF voice and data communications. The RT7700H is
the transceiver component of Datron’s 7700-Series Strategic HF
Communications System. The RT7700H is fully interoperable with
Datron’s Spectre HTM PRC7700H tactical manpack.
