Programmable Vfo; Beat Shift; If/ Detect Output Mode - Kenwood TH-D74A User Manual

PROGRAMMABLE VFO

selectable. For example, if you select 144 MHz for the lower
limit and 145 MHz for the upper limit, the tunable range will
be from 144.000 MHz to 145.995 MHz.

lower limit frequency.

BEAT SHIFT

various transceiver functions, the CPU clock oscillator's
harmonics or image may appear on some spots of the
reception frequencies. Select a Beat Shift setting from Type 1
~ Type 8, which does not cause interference.
