The spot function allows you to conveniently mark or
store a DX station calling frequency temporarily.
When tuning across the memorized frequency, a
beep sounds to alert you. The spot frequency can
be programmed for each band.
This function can be turned OFF using set mode
with the [kHz/MHz] switch. (p. 48)

@ Select VFO mode.
© When a frequency to be marked appears, push
[FUNC] then [kHz/MHz*SPOT].
@) Operate on other frequencies.
) Rotate the tuning dial to return to the frequency.
-A beep tone is emitted when tuning across the
frequency.
© Optional tone squelch operation
To operate the tone squelch, an optional UT-84 is
required. See p. 51 for installation.
The tone squelch opens only when receiving a
signal with the same pre-programmed subaudible

members using the same tone. You can check the
tone frequency using the tone scan if desired. (p. 32)

or no tone, the squelch does not open, however, the
S-meter indicates the signal strength.
