IC-746 Pro Twin Passband Tuning

Icom 746 Pro PBT

The Icom IC-746Pro Twin Passband Tuning function electronically narrows the IF passband width by shifting the IF frequency to slightly outside of the IF filter passband to reject interference. This transceiver uses the DSP circuit for the PBT function. Moving both [TWIN PBT] controls to the same position shifts the IF. The LCD shows the passband width and shift frequency graphically.
