Clarifier - Honeywell KHF 1050 Pilot's Manual

4. Press the ENT button on the end of the right knob. The selected
channel is stored and the receive frequency will begin flashing.
5. Use the right inner and outer knobs to select the desired receive fre-
quency. Remember to check ground station requirements as to the
need for simplex or semi-duplex operation.
6. Press the ENT button. The selected receive frequency is stored and
the Mode will begin flashing. Only USB V is available when program-
ming an emergency channel.
7. Press the ENT button. The selected Mode is stored and the transmit
frequency will now begin flashing.
8. If the emergency channel requires simplex operation, again press the
ENT button to store the automatically displayed transmit frequency. The
channel window now displays the next available emergency channel
number.
9. If the channel requires semi-duplex operation, use the right inner and
outer knobs to select the desired transmit frequency. Press the ENT but-
ton. The transmit frequency is stored and the channel window now dis-
plays the next available emergency channel number. Again, check the
ground station requirements as to the need for simplex or semi-duplex
operation.
NOTE: On any Emergency Channel with separate receive and transmit
frequencies, simplex operation will occur on the programmed channel's
transmit frequency when the channel is first selected.

CLARIFIER

The purpose of the Clarifier is to help elimi-
nate the unnatural "tinny sound" found at
times with SSB audio voice quality as a
result of off-frequency ground station
transmissions. The Clarifier works by
allowing frequency adjustment of ±250 Hz
whether the channel involved is semi-
duplex or simplex tuned. It is not normally
used in the AM mode.
Long range HF signals received under less
than optimum propagation conditions may
still vary in quality and volume.
