Transmitter Performance Check; Operation - Honeywell KHF 1050 System Installation Manual

Preliminary - Subject to Change Without Notice
These stations are located in Fort Collins, Colorado and
Kekaha, Hawaii. Consult the HF frequency propagation chart
in Table 2001 for an overview of the frequency to use for
a particular time of day and distance from the
transmitter. These stations transmit in the AM mode.
However, they can be received by the KHF 1050 System in
the USB Voice (UV), LSB Voice (LV), AM or Reduce-Carrier
(RC) modes.
If a signal can not be heard,check the connetion to the
antenna, the antenna itself and ensure that all coaxial
cables that interconnect the KHF 1050 System are properly
connected.
4. Adjust the squelch level as needed to LOW, MED or MAX to
achieve the minimum level required to suppress the
receiver noise with no signal present.
2.C. Transmitter Performance Check
1. Select the HF positon on the audio panel microphone
switch.
CAUTION: VERIFY THAT NO ONE IS STANDING ON THE GROUND NEAR
2. Select a channel on which the aircraft is authorized to
transmit, with the apropriate mode of operation, which is
typically USB Voice (UV). Momentarily press the PTT switch
to start the antenna tuing process.
Assuming the KAC 1052 Antenna Coupler has not previously
been on this frequency, the antenna coupler will begin to
tune to the antenna and the controller display will begin
to indicate that tuning is taking place. Refer to the
controller information for the details of how tuning is
annunciated by the particular controller being used.

THE AIRCRAFT OR TOUCHING THE AIRCRAFT. WITH MANY
TYPES OF AIRCRAFT HF ANTENNAS, THE ENTIRE
AIRFRAME BECOMES PART OF THE ANTENNA. ANYONE
STANDING ON THE GROUND COULD RECEIVE AN
ELECTRICAL SHOCK IF TOUCHING THE AIRCRAFT, OR IF
ENTERING OR EXITING THE AIRCRAFT DURING A
TRANSMISSION BY THE KHF 1050 SYSTEM. DO NOT
