and increases the S/N of the target signal. These
characteristics play an effective role in picking up
very weak signals in the 50 MHz band, for example.
The shape factor is kept, and the sharpness of the
bandpass is excellent.
IPPlusfunction
The IP Plus function improves the Intermodulation
Distortion (IMD) quality by exerting the direct sampling
system performance.
This function optimizes the Analog/Digital Converter
(ADC) against the distortion when you receive a
strong input signal. It also improves the Third-order
Intercept Point (IP3) while minimizing the reduction of
the receive sensitivity.
1. Push .
FUNCTION
• The FUNCTION screen is displayed.
2. Touch [IP+].
LTouch [IP+] to turn the IP Plus function ON or OFF.
L Select ON to prioritize the IP quality, and select OFF
to prioritize the receive sensitivity.
3. To close the FUNCTION screen, push
• "IP+" is displayed when ON is selected.
NoiseBlanker
The Noise blanker eliminates pulse-type noise such
as the noise from car ignitions.
The Noise blanker cannot be used in the FM mode.

may be distorted if they are excessively strong or the noise
is other than a pulse type. In that case, turn the OFF Noise
Blanker,orshallowtheDEPTHontheNBmenu.
