![NB2NB2 is a function for blanking pulse noise with a long pulse widthwhich cannot be blanked by NB1. NB2 is further divided into TypeA and Type B, which can be employed according to thecircumstances. NB2 can also be used together with NB1.Type A.Type A suppresses mainly the pulse noise without blanking the target signal. The level of the effect (Level) can be adjusted.Type ATarget SignalPulse Noise●As pulse noise remains after blanking when “Type A” isused, pulse noise might be audible when the targetsignal is strong or when there is strong interferencewithin the passband. Even in such a situation, it has theeffect of bringing up the target signal when AGC gain islow due to pulse noise.●“Type A” is most effective in cases where weak targetsignals are buried in strong pulse noise.Type B.Target SignalPulse Noise As with NB1, Type B blanks the pulse noise together with target signal. The pulse sensitivity level (Level), blanking duration (Width) and attenuation level (Depth) can be adjusted.Type BWhen pulse noise with a long pulse width is blanked using“Type B”, the time interval for which the target signal isremoved becomes longer due to the long blanking time,and this causes the silence period to stand out.1Press and hold [NB2] to display the Noise Blanker2 configuration screen.2Press F6 [TYPE].Pressing F6 [TYPE] each time toggles the screen between“Type A” and “Type B”.Type A Screen.Type B Screen.●Pressing and holding [NB2] displays the noise blanker2 screen which shows the current type in use.●The default setting is “Type A”.●Type selection is separately available for audio mode(SSB/AM (including DATA mode)) and non-audio mode(CW/FSK/PSK).Configuring the NB2 Effect Level (Type A)/ NB2 PulseSensitivity Level (Type B)1While the Type B screen is displayed, press F2[]/ F3 [ ] to select “Level”.2Press F4 [–]/ F5 [+] or turn the [MULTI/CH] controlto change the level.SettingValue 1 to 6 (default) to 10 (1 step)•Type A: Configuring to a larger value reduces the noise further.•Type B: Configuring to a larger value blanks the RX signaland pulse noise with small difference in signal level.●Configuring to a value with a higher level of noise blankereffect may cause the transceiver to malfunction anddistort the RX audio depending on the condition of theRX signal or interfering signal.Configuring the Blanking Duration (Type B Only)1Press F2 [ ]/ F3 [ ] to select “Width”.2Press F4 [–]/ F5 [+] or turn the [MULTI/CH] controlto change the blanking duration.SettingValue 1 to 10 (default) to 20 (1 step)•Configuring to a larger value lengthens the blanking time.Configuring the NB2 Attenuation Level (Type B Only)1Press F2 [ ]/ F3 [ ] to select “Depth”.2Press F4 [–]/ F5 [+] or turn the [MULTI/CH] controlto change the attenuation level.SettingValue 1 to 20 (default) (1 step)•Configuring to a larger value increases the attenuation level.Notch FilterNotch filter is capable of suppressing beat interference at the IF level.It can be employed to eliminate beat noise and bring up weaksignals or during operation while checking the noise condition.The notch filter can be used in the SSB, CW, FSK, PSK and AM modes.Turning ON/OFF Notch Filter1Press [NCH].Pressing [NCH] each time toggles the notch filter between ONand OFF.•When the notch filter is ON, “NOTCH” is displayed on thescreen.•When notch filter is ON, an indicator showing the notch pointis displayed in the RX filter passband characteristics insidethe filter scope..2Turn the [NOTCH] control.Adjust the notch frequency to the point where beat orinterference is to be suppressed.6 REJECTING INTERFERENCE6-6](https://usermanual.wiki/JVC-KENWOOD/512000.Users-Manual-2/User-Guide-3944946-Page-48.png)
