UTILIZING THE B-BAND
32
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/ 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.
