4 RECEIVING AND TRANSMITTING Digital Selector You can manually adjust the center frequency of the automatic preselector using the Digital Selector function. The automatic preselector adds selectivity ahead of the 1st mixer. This reduces intermodulation distortion from nearby strong signals. The automatic preselector tracks the frequency tuning by changing its resonant frequency in discrete steps. The Digital selector is used within the ham band, except for the 50 MHz band.
