Icom IC-7800
Preselector

The IC-7800 preselector works from 1.5 to 30 MHz. The preselector automatically tracks the intended signal, keeping the preselector's bandwidth centered on the operating frequency at several kHz steps (minimum). The preselector rejects unwanted out of band interference from multi-multi operation or strong broadcast stations, as your first line of defense against interfering signals. The center frequency of the preselector is adjustable from the DIGI-SEL tuning knob on the front panel.
