Australia’s Barrett Communications launched its new PRC-4090 tactical high frequency (HF) software-defined radio (SDR) at the 2019 Defence and Security Equipment International exhibition (DSEI 2019) held in London from 10 to 13 September.
Leveraging technology developed for Barrett’s commercial PRC-4050, the new radio can be used in three configurations: manpack, mobile (vehicle-borne), or as a base station, with selectable power outputs of 10, 30, 125, and 150 watts. The radio, which is constructed of a light-weight alloy, weighs 2.95 kg and measures 241×53×331 mm.
It offers 1,000 channels with a frequency resolution of 1 Hz, and 2G and 3G automatic link establishment (ALE). Options include frequency hopping at 5 or 25 hops per second, digital voice, and AES 256 and DES 56 encryption. A Barrett representative said that the non-ITAR DES 56 is useful for the wider export market.

For the manpack role, Barrett has developed a 2.05 kg 16Ah Li-ion battery that fits on the side of the radio, with the same profile. With a consumption of 250MA, in the receive-only mode the transceiver can operate for up to 64 hours, and with a 1:9 receive/transmit ratio it has a life of 21 hours. The battery incorporates an embedded charging system for recharging from a 24V DC source. It can also be connected to an additional battery. Alternatively, the radio can be used with a non-rechargeable battery pack.
