General Specifications

The KHF 1050 HF System is a solid state design with 200 watts PEP of output
power, supplied by 28 VDC, with an operational frequency range of 2.0 to 29.9999
MHz with 100 Hz resolution. The KHF 1050 HF System has been type accepted by
the FCC and TSO approved.

System Operating Modes

3.B.(1) Emission Modes
Several operating mode options are available for the KHF 1050 HF system to
meet particular operational needs.
USB Voice (upper sideband) and AME (amplitude modulation equivalent) are
standard modes of operation that should be enabled on all system
configurations. Virtually all air traffic control communication is conducted in
USB voice mode.
LSB (lower sideband) operation is not used by stations operating in the aviation
services under FCC Part 87 (USA) regulations. LSB may be enabled for use in
regions or applications where its use is authorized.
AM or AME (amplitude modulation equivalent) may be used in some areas that
lack single-sideband (SSB) capabilities. AME is a form of amplitude modulation
that is more efficient than full AM, yet compatible with AM systems.
USB Data and LSB Data are the same as the above-mentioned USB and LSB
modes, except receiver audio and transmitter audio are connected to a
data-modem rather than to a speaker or microphone.
