HF-80 Series, the replacement fixed site technology for the URG-II systemsUpdated: 2 March 2014The Rockwell Collins HF-80 series is a late 1970 to early 1990 High Frequency radio system. The primary use of the HF-80 was in fixed sites and in military communication shelters.Similar to its earlier brother, the URG-II, it is based on a series of system elements.Shown is Jim Stitzinger's excellant collection of HF-80 element lists and part numbers.The HF-80 was a popular replacement technology that was used by both the military users and the commercial HF markets. It was used extensivily around the world in the various aviation services.The HF-80 series technology was often deployed in remote sites as the technology allowed for remote control over considerable distance. The sites could be configured as a composite site or as split sites with separate transmit and receive functions.The technology was originally used with ALE 1st Generation and later upgraded to support 2nd Generation.Basic Specifications:Frequency Range: 2.00000 Mhz to 29.99999 MHz (100 or 10 Hz steps depending on version)Channels: 280,000 or 2,800,000 (see above)Modes: AM/CW/SSB (LSB/USB plus A2 and B2), SSB channel is 2.85 KHz wideup to 4 channel ISB operationData capable:YesFull duplex capable: Yes (separate transmit and receive capable)Split site capable: Yes (this was a common event)External freq.
