(7) RF OUTPUT POWER CONTROL
Continuously variable control for adjusting the RF out-
put power of the transmitter in all modes for QRP op-
eration. To reduce the RF output power rotate the con-
trol counterclockwise. To increase rotate the control
clockwise. The power output is a linear control, there-
fore the peak to average output power ratios remain
constant regardless of power level.
(8) ECHO DELAY CONTROL
Varies the amount of delay, or duration of the echo
repetition. Rotate clockwise to increase the amount of
delay and counterclockwise to decrease.
(9) ECHO ON/OFF and VOLUME CONTROL
Turns on and off the echo feature, and varies the vol-
ume or number of echo repetitions. To turn on the echo
feature and increase the echo volume, rotate the con-
trol clockwise. To turn off the echo feature rotate the
control completely counterclockwise to the OFF posi-
tion.
(10)ALL MODE TALK BACK CONTROL
All Mode Talk Back, a Magnum exclusive, is an inde-
pendent talk back monitor. The AMT functions in all
modes and allows the operator to monitor the trans-
mitted audio of the DELTAFORCE. To increase the
volume of the talk back rotate the control clockwise.
To decrease rotate counterclockwise. To turn off the
talk back rotate the control completely counterclock-
wise.
(11)CLARIFIER
Allows variation of the receiver operating frequency
above and below the indicated frequency in all modes.
The receive clarifier is primarily used in tuning to an
SSB signal. The receive clarifier has a range of +/-1
kHz above and below the indicated frequency.
(12)FREQUENCY
Rotate clockwise to increase the operating frequency
and counterclockwise to decrease the operating fre-
quency.
(13)METER
The meter indicates receive signal strength, RF out-
put power, SWR calibrate and SWR. The top horizon-
tal bar graph indicates calibration and measuring of
the standing wave ratio. The center bar graph indi-
cates RF output power. The bottom bar graph indi-
cates receive signal strength.
IMPORTANT!
Operating some of the features in 14 through 21
require the use of the function control. To activate
the function control, momentarily push the FUNC
(15) control, the FUNC prompt will be displayed in
upper left-hand corner of LCD. Push the control
again to deactivate the function control.
(14)SCAN
Scans frequencies in increments of 10 kHz. There are
two ways to scan using front panel entry.
(1) Receive Audio On Scanning: Press the SCAN but-
ton. Scan rate is one step every 5 seconds. To stop
scanning press the SCAN button again, or momen-
tarily press the PTT button on the microphone (scan-
ning will stop without transmitting).
(2) Receive Audio Mute Scanning: Carefully rotate
squelch control to the threshold (see 2). The receiver
scan rate will now be five steps per second. When a
signal is detected the squelch is automatically disen-
gaged and the scanning is paused. The squelch cir-
cuit will automatically reengage and the receiver will
continue to scan the moment the received signal is no
