CHANNEL OPERATION AND PROGRAMMING
The 19 pilot programmable channels available with the KFS 594
Control Display Unit can be easily programmed by the pilot on the
ground or in the air. Each of the 19 channels can be assigned a sep-
arate frequency or frequencies (semi-duplex operation). The operat-
ing mode (USB, LSB or AM) of the stored channel is determined by
the position of the MODE selector knob at the time the pilot is using
the channel.
Two types of channels can be programmed:
1. Simplex. The pilot programs the same frequency in receive and
transmit.
2. Semi-duplex. The pilot programs two different frequencies, one for
receive and one for transmit.
To gain access to channelized operation with the KFS 594, make
sure that the mode selector knob is in the desired position (USB, LSB
or AM) and that a channel number is showing in the display (upper
left). If one is not showing (direct tune operation), or if you wish to
change the channel, move the “cursor” by pressing the
Frequency/Channel control knob until the channel number is flashing.
Change the channel number by rotating the Frequency/Channel con-
trol knob until the desired channel number appears. The previously
programmed receive frequency associated with that channel will
appear in the display.
If no reprogramming of channels is required at this time, the KHF
950/990 is made ready for channelized operation on the selected
channel number by tuning the antenna (momentarily keying the mic).
If channel programming is required, you are now ready to program
