DReceiving method

➀Connect a terminal unit as above.

➁Select FM mode (or USB, CW modes for HF band data communications).

➂Set the receiver to the desired frequency as below.

➃Set the connected terminal unit to the appropriate settings.

•Refer to the terminal unit’s instructions.

Frequency settings depend on the mode used.

FM mode: [Setting frequency(displayed freq.)]=[Desired freq.]

USB mode: [Setting frequency(displayed freq.)]=[Desired freq.]–[Center of Mark and Space freq.]

CW narrow mode: [Setting frequency(displayed freq.)]=[Desired freq.]–[Center of Mark and Space freq.]+[600 Hz]

LSB mode (for amateur RTTY): [Setting frequency(displayed freq.)]=[Desired freq.] + [Mark freq.]
