UTILIZING THE B-BAND

ABOUT THE B-BAND

Usually you can communicate with other amateur radio stations using A-band frequencies for receiving and transmitting. This transceiver also features another receiver in addition to the A-band transceiver. The frequency for the B-band appears on the bottom part of the display. Although the A-band transceiver covers only the 2 m/ 1.25 m (TH-F6A only)/ 70 cm amateur radio bands in FM mode, the B-band receiver can receive signals from 100 kHz to

470 MHz in SSB, CW, FM, or AM mode, and from 470 MHz to 1.3 GHz in FM or AM mode.

In this way, you can monitor 2 different frequencies at the same time. For example, you can listen to a local FM broadcasting station on the B-band while you are monitoring your club channel on the A-band.

If one of the A-band amateur radio bands is selected for the B-band receiver in FM mode, you can also transmit on the B-band frequency.

B-BAND FREQUENCY

Since the B-band frequency coverage is so wide, the default frequency band, mode, and frequency step size are preprogrammed as shown below.

1Press [A/B] to select B-band.

The “s” icon moves, indicating which band is currently selected for operation.

2Press [BAND] until the desired frequency band appears.

Each time you press [BAND], the frequency band cycles from the last band you selected to the upper band frequency. When it reaches the 23 cm band, it returns to the AM band.

You can also press []/ [] to select your desired band in VFO mode {page 7}.

3Turn the Tuning control or press []/ [] to tune to a desired frequency.

Note: You can also select one of the amateur radio bands to transmit on the B-band frequency. However, you must be operating in FM mode to transmit.
