Installation Guide for KHF 1050

The KHF 1050 HF voice and data communication system is a solid state design with 200 watts (PEP) of output power, operating at 28 Vdc. It operates between 2.0 and 29.9999 MHz with 100 Hz resolution, and can be strapped to limit the upper frequency to 22.9999 MHz. Operations are limited to 25 MHz for aircraft installations due to aeronautical mobile band frequency limits. The system supports USB (A3J) and AME (A3H) modes, with LSB (A3J) being restricted by FCC regulations but may be used where authorized. An optional mode A3A (USB reduced carrier) may be available. The system operates in a channel (frequency preset) or direct frequency mode. It stores frequency, mode, and channel data; displays frequency; provides synthesizer tuning information; controls tuning and transmit logic; switches bands; tunes antennas; and has a built-in test with fault display.
