nals. Heavy squelch can be used to advantage in crowded city locations to squelch
out weak inteferring signals.
c) RIT and DISCriminator Meter: -- Reception may be impaired if the incoming sig-
nal is off frequency, particularly with weak signals, In such instances pull out
the RIT knob to switch the meter to the DISC position and adjust RIT knob to center
the needle.
d) Memory WRITE Procedure: -- This transceiver has 1,000 channels, and any 4 may
be written in to the memory, such as frequently used frequencies. For example, if
it is desired to store the frequency of 146.520MHz in memory channel 1 --
1. Use frequency controls and set up 146.520MHz as read out on the DISPLAY.
2. Set MEMORY switch to 1. (If nothing had been stored in this channel pre-
viously, LED display will go black at this point.)
3. Switch WRITE switch to WRITE position and then return to OFF. As soon as
switch is set to WRITE position, the LED display will show 146.520MHz in~
dicating that the frequency has been written in to the memory channel.
4. Other sequences of writing in frequencies are equally satisfactory and
will not damage the transceiver.
5. NOTE: Inadvertent operation of WRITE switch even with MEMORY switch in
OFF position will result in selected frequency being written in to memory
channel No. 4. This feature can be used to advantage for temporary stor-
age of frequencies, retaining the other channels for storage of repeatedly
used frequencies.
e) Scanning: --
1. Set MEMORY switch to SCN position next to memory channel 4.
2. Operate SCAN switch to CLOSE or OPEN as desired. The receiver will imme-
diately start scanning each memory channel consecutively and the DISPLAY
LEDs will show the frequencies in each of the memory channels as they are
scanned. If the CLOSE mode was selected, scanning will cease at the
first channel found with an incoming signal. As soon as this signal dis-
appears, scanning will resume until another signal is received. In ‘the
OPEN mode scanning will cease at the first vacant channel encountered. Use
CLOSE mode for continuous monitoring of up to 4 channels, and the OPEN
mode for quickly locating a vacant channel.
3. If it is desired to transmit using a channel located by scanning, return
the SCAN switch to the center OFF position. Transceiver will stay on the
frequency (memory channel) located by scanning until MEMORY switch is mov—
ed off the SCN position.
f) RF ATTenuator Switch: -- Switching to the RF ATT position reduces sensitivity
of the receiver by approximately 10dB's. This is useful when encountering inter-
or cross modulation problems due to an extremely strong signal. This is also useful
for squelching out weak interferring signals aswellas in plotting a radiation pat-
tern of a directional beam antenna.
3. . TRANSMITTING: --
a) Select HIGH power (15 watts) or LOW power (1 watt) as desired.
