AN/ARC- 229/230 Airborne HF Radio Group / HF Radio
The HF-121C high performance radio system is designed for HF applications requiring voice and data operations including 400W transmit power. Compatible with the requirements of MIL-STD-188-203-lA for Link 11/TADIL A, this 400 Watt PEP/Average power radio provides maximum performance for airborne applications.
The HF-121C has been optimized for tactical digital data communications and simultaneous operation (SIMOP) of multiple radio sets with minimum frequency and antenna separation. Embedded Automatic Link Establishment (ALE), MIL-STD-188-110A Modem, and ARINC 714-6 SELCAL capabilities are also available. The basic radio set is partitioned into a receiver-exciter with integral pre/postselector on a mounting shelf, and a power amplifier-power supply on a mounting shelf. The receiver-exciter can be used independently of the power amplifier. Serial control via RS-232 or MIL-STD-1553B is available.
The HF-121/A/B/C family of radios has been installed in commercial and military aircraft in the United States and in foreign countries. It has been selected as the standard HF radio by many aircraft manufacturers. Earlier versions of the HF-121 product line have received military nomenclature designation of AN/ARC-153, -157, -191(V), -207(V), AN/URC-91, and -97(V) by the United States and AN/ARC-512 for other nations.
The AN/ARC-229/230 is manufactured by Rockwell-Collins for the Air Force's E-3B and E-3C.
