SELECTING A MODE FOR THE B-BAND

When using the B-band receiver, the following receiving mode is available.

Receiving Mode

Available Frequency Ranges

 

 

LSB/ USB

100 kHz f < 470 MHz

 

 

CW

100 kHz f < 470 MHz

 

 

AM

100 kHz f < 1.3 GHz

 

 

FM

100 kHz f < 1.3 GHz

 

 

WFM

29.7 MHz f < 1.3 GHz

 

 

LSB/ USB/ CW/ AM/ FM/ WFM

To select the receiving mode for the B-band:

1Press [VFO].

2Press [A/B] to select the B-band.

3Press [BAND], then turn the Tuning control or press []/ [] to select the desired frequency.

4Press [F], [BAND] repeatedly until you select the desired receiving mode. The mode icon cycles from FM WFM AM LSB USB CW, and then goes back to FM.

Note:

“FMN” appears in place of “FM” when you select “ON” for the Menu No. 29 (FM NARROW) {page 39}.

Select “WFM” when you receive the audio signal of the broadcasting stations, such as FM or TV stations.

If the Fine Tuning function is ON {page 35}, you cannot select FM mode (FM/ NFM/ WFM). To select FM mode, turn the Fine Tuning function OFF.

BAR ANTENNA

Although the supplied wide-band helical antenna is used for receiving B-band frequencies, due to the size and length limitation, it may not be suitable for low HF band (below 10.1 MHz) reception. The transceiver features a built-in bar antenna for the reception frequency below 10.1 MHz. The transceiver automatically switches to the bar antenna when you select a frequency below 10.1 MHz for the B-band. However, you can connect an external antenna to the antenna connector instead.

To disable the built-in bar antenna below 10.1 MHz:

1Press [MNU].

2Turn the Tuning control or press []/ [] to select Menu No. 26 (BAR ANT).

3Press [] or [MNU].

4Turn the Tuning control or press []/ [] to select “DISABLED”.

5Press [] or [MNU] to store the setting.

Note: The bar antenna is embedded in the base of the transceiver, horizontally. The antenna has the same characteristics as a dipole antenna. If the target station’s signal is weak, rotate the transceiver to find the best receiving position.
