1
Sampling Rate
(Default: 5.12MHz (BW = 4.48MHz))
Select the sampling rate value of the signal that is
input to a PC.
L
If the audio is interrupted, select a lower sampling rate value.
L
If the sampling rate value is too low, a sharp spike (a DC)
is displayed at the LO frequency position. See page 5
about how to remove a sharp spike.
2
Bit
(Default: 16bit)
Select bit depth of the signal that is input to a PC.
L
If
Sampling Rate
(
1
) is set to “5.12MHz (BW =
4.48MHz),” bit depth is set to “16bit.”
3
ANT
(Default: ANT1)
Select antenna connector ANT1, ANT2, or ANT3.
L
While operating between 30 and 3000 MHz frequency
band, only the ANT1 connector can be used.
4
P.AMP
(Default: OFF)
Select whether or not to enable the Preamplifier
function.
The preamp amplifies received signals in the receiver
front end to improve the signal-to-noise ratio and
sensitivity.
A preamp is used when receiving weak signals.
5
IP+
(Default: OFF)
Select whether or not to enable the IP Plus function.
The IP Plus function improves the Intermodulation
Distortion (IMD) quality by optimizing the direct
sampling system performance.
6
ATT
(Default: OFF)
Select the attenuator setting.
The attenuator prevents a desired signal from
becoming distorted when a very strong signal is near
the frequency, or when a very strong electric field, such
as from a broadcasting station, is near your location.
7
HF BPF
(Default: ON)
Select whether or not to use the receiver’s BPF when
operating the HF band.
L
If an excessively strong signal is received, turn ON this
function.
8
RF Gain
(Default: MAX)
Adjust the RF gain (sensitivity).
9
TS (Tune Freq)
(Default: 1k (except for FM mode)
25k (FM mode))
Select the tuning steps when you set the Tune
frequency using the RC-28.
L
If the TS function is OFF, the tuning step is set to 10 Hz.
L
When rotating [Main dial] to set the LO frequency, the
tuning step depends on
Sampling Rate
(
1
).
