•During SSB data mode, 1⁄4 tuning function can be used for critical tuning.

yOperate the PC (software) or TNC to transmit.

•When operating in SSB data mode, adjust the TNC out- put level so that the ALC meter reading doesn’t go out- side the ALC zone.

NOTE: When SSB data mode is selected, the audio

input from the [ACC1] (pin 6) is used for transmis-

sion instead of [MIC]’s.

The fixed condition is used for SSB data transmis-

sion as follows:

 

• [COMP]

: OFF

• Tx bandwidth

: MID

• Tx Tone (Bass)

: 0

• Tx Tone (Trebles): 0
