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.
