PT-8000 A · B · C User Manual
During independent sideband operations MAIN- and SUB-RX are tuned to the
same frequency but on different sidebands. Both sidebands are transmitted
and modulated independently.
Pressing ISB will call up the ISB menu:
„0dBm" input (connected to MIC jack) will be transmitted on USB/LSB –
depending on status of ISB NORM/INV
DATA input (connected to J17 on rear panel) will be transmitted on USB/LSB
– depending on status of ISB NORM/INV
ISB normal - 0dBm or DATA input are transmitted on USB. Voice will be on
LSB
ISB inverse - 0dBm or DATA input are transmitted on LSB. Voice will be on
USB
In ISB mode one sideband is selected for transmission of data either trough
„0dBm" or „DATA" input either on USB (ISB normal) or LSB (ISB inverse).
The other sideband will always transmit the voice signal fed trough the MIC-
jack at the front panel.
