AF Gain Control: (4)
Note this is a dual concentric knob. The
inside knob controls the audio volume level
to the speaker or headphones.
RF Gain Control: (5)
The outer ring on this control increases or
decreases the receiver IF gain. It is a general
rule on the more modern DSP transceivers
such as the Eagle to adjust the RF gain fully
clockwise and then slowly back down the
control (counter clock wise) until you reach a
convenient signal to noise ratio. You will
discover this control will vary from band to
band. As you lower the RF gain it may be
necessary to increase the AF gain to get a
comfortable listening level.
AGC: (14)
Eagle allows for 3 convenient AGC setting
FAST – MEDIUM – SLOW
. For most
sideband operation a slow AGC is usually
preferred. The letters
F – M or S
will appear
on the screen when you toggle to your
favorite setting. To change the AGC setting,
(a secondary button function)
First press FNC until button and FUNC begin
to flash. Next, press the AGC/LOCK button
until desired setting appears. Exit by pressing
FNC button.
The AGC setting utilized in a given mode
will be recalled when that mode is used again.
NR: (9)
To activate the DSP noise reduction just press
the NR button to turn this feature on and off.
When turned on, NR will appear on the front
screen. Press and hold NR to bring on screen
the settings from 1-10. The multi knob will
allow you to adjust the noise reduction value
for your comfort level. Press NR again to
exit the adjustment mode. The noise
reduction system used in the Eagle is a
wonderful tool that can assist you in hearing
weak signals under noisy band conditions.
Under some conditions the NR may affect the
quality of a received signal when certain
noise and band conditions are present. Often
times experimenting with this tool under
varied signal strength and band noise such as
atmospheric noise will make for a more
pleasurable listening experience. Most of the
time you will discover that DSP noise
reduction will not be necessary especially
with strong incoming signals.
PRE: (16)
The preamplifier in the Eagle is designed to
give you a 12dB increase in signal strength.
It is best suited for weak signal reception. To
activate the receiver preamp, first press FNC,
(a secondary button function) until both
button and FUNC begin to flash. Next, press
the PRE/ATTN button to activate. Exit by
pressing the FNC button.
