Because this is a simplex channel, simply press the STO button a
second time to store the same frequency in the transmit portion of
memory.
After the STO button is pressed the second time, the “cursor” will
stow and the flashing dash will disappear to indicate the KFS 594 is
no longer in the program mode. Additional channels can be pro-
grammed by continuing to use the “cursor” and Frequency/Channel
control knob in this manner.
5. Tune the antenna. Key the mic to tune the antenna. After tuning
is completed you are ready to transmit.
SEMI-DUPLEX CHANNEL PROGRAMMING
Semi-Duplex operation uses one frequency for receiving and another
for transmitting. The KFS 594 has semi-duplex capability with all 19
pilot programmable channels. As before, to gain access to channel-
ized operation, make sure that the mode selector is in the desired
position (USB, LSB or AM) and that a channel number is showing in
the upper left of the display. As previously described, use the
Frequency/Channel control knob to select the channel to be pro-
grammed. You will note that the first three steps in programming a
semi-duplex channel are the same as for programming a simplex
channel.
1. Change the first digit of the receive frequency to enter the
program mode. By pushing the Frequency/Channel control knob
move the “cursor” to the first digit in the frequency to be changed.
Twist the Frequency/Channel control knob until the desired number
has been selected for this frequency digit. As the knob is twisted, a
flashing dash will appear to the right of the channel number to signify
that you are in the program mode. You will be unable to receive or
