Harris Corporation's RF-5710A HF radio modem adopted as NATO Standard

Harris Corporation's new RF-5710A high-frequency (HF) modem was recently used in a series of NATO tests to select a high-speed HF waveform for NATO use. The new NATO standard, known as STANAG 4539, provides for transmission over long distance HF radio circuits at rates up to 9,600 bps.

The United States submitted its new military standard (MIL-STD-188-11 0B) high-speed HF waveform as a candidate for the new NATO standard using a Harris RF-5710A modem, which incorporates a unique adaptive equaliser that allows transmission over HF radio channels at rates up to 12,800 bps. After extensive testing of the RF-5710A modem at the Defence Evaluation and Research Establishment (DERA) in the United Kingdom, the waveform was selected over several other candidate waveforms.

The Harris RF-5710A modem is now in production with the new MIL-STD-188-110B (3,200 bps-12,800 bps) waveform. It also supports a number of other interoperable waveforms, including STANAG 5066, STANAG 5065, STANAG 4529, STANAG 4481, STAN AG 4415, and STANAG 4285.
