3. System Leading Particulars
3.A. 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 100kHz resolution.
The KHF 1050 HF System has been type accepted by the FCC and
TSO approved.
3.B. 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 (upper sideband, A3J) AME (amplitude modulation
equivalent A3H) are standard modes of operation permitted
on all system configurations.
LSB (lower sideband, A3J) operation is not permitted for
stations operating under Part 87 FCC (USA) regulations.
LSB may be enabled for use in regions or applications
where its use is authorized.
AM or AME (amplitude modulation equivalent, A3H) 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 connectedto a data-modem rather than to a
speaker or microphone.
A seldom used mode A3A (USB reduced carrier) is available
for use in locations that may utilize the mode.
Table 25, Modes of Operation, lists the modes of operation
applicable to the PS440, MCDU and RM-855.
