FRONT PANEL CONTROLS
1. SQUELCH
Used to eliminate background or “white” noise when
monitoring strong signals. To properly adjust the
squelch circuit, start rotating the control slowly
clockwise until the received white noise disappears.
2. VOLUME (OFF)
(OFF)
: Turns the radio on and off. To turn the radio
off rotate the control counterclockwise until it clicks.
VOLUME
:
Adjusts the AF gain, or volume of the
receive audio. Turn clockwise to increase and
counterclockwise to decrease.
3. ECHO DELAY
Varies the amount of delay, or duration of the echo
repetition. Rotate clockwise to increase the amount of
delay and counterclockwise to decrease.
4. ECHO VOLUME (OFF)
(OFF)
: Turns the echo feature on and off. To turn the
echo off rotate the control counterclockwise until it
clicks.
VOLUME
: Varies the volume or number of echo
repetitions. To increase the echo volume, rotate the
control clockwise.
5. RF GAIN
Adjusts the receiver sensitivity to both signals and
background noise. This affects the distance at which
a signal can be detected. Turning the control
counterclockwise reduces the receiver sensitivity.
This is particularly useful in areas where large
volumes of signals are present. The S/RF display
(“SIG” bar) indicates the received signal’s strength.
6. RF POWER
The transmitted power of the MAGNUM 1 may be
varied from 0 to 40 watts peak in all modes. Rotate
clockwise to increase RF output power. Rotate
counterclockwise to decrease RF output power.
7. FREQUENCY
: Rotate clockwise or counterclockwise
to select the desired frequency. To change frequency
step see 10. Clarifier.
8. BAND (A~F)
Band control positions A ~ F splits the radio frequency
range into smaller sections for quicker tuning across
the radio’s frequency range.
A: 24.890 ~ 24.990 MHz (12 Meter Band)
B: 28.000 ~ 28.395 MHz (10 Meter Band)
C: 28.400 ~ 28.795 MHz (10 Meter Band)
D: 28.800 ~ 29.195 MHz (10 Meter Band)
E: 29.200 ~ 29.595 MHz (10 Meter Band)
F: 29.600 ~ 29.700 MHz (10 Meter Band)
9. OPERATING MODE
The operating mode switch allows selection of PA,
CW, AM, FM, USB and LSB modes.
PA, or Public Address, mode allows the user to
transmit their voice over a loudspeaker (PA horn)
when connected to the transceiver. To use this
feature, connect a PA horn to the external speaker
jack on the back panel. Refer to Menu Settings
section for additional PA features.
CW, or Continuous Wave, is for Morse Code
communications. To operate Morse Code a CW key,
or paddle, is connected to the CW Key jack on the
back panel of the transceiver. Refer to Menu Settings
section for additional CW features.
