Fig. 4-1 Control and Switch Settings

4.1 RECEPTION

First connect the antenna, microphone and key. Then, set
the controls and switches referring to Fig. 4-1.

In 858, the USE band is normally used for reception of
signals of more than 10 MHz. The 888 mode of the
TS-660 is automatically set to USB.

Ascenain that the TS-660 is ready for operation, then turn
the POWER switch ON. A beep is heard and the meter is
illuminated. Also. the digital display indicates "H"
and 55,050.5", indicating that the transceiver is in
operation.

The transceiver is fully solid»state, allowing reception as
soon as the POWER switch is turned ON.

Next, depress the BAND switch (30) to tune in the desired
band. Turn the AF GAIN control clockwise until some
receiver noise is heard from the speaker. Adjust the volume
to a suitable level.

Turn the VFO tuning control slowly so the desired signal
can be heard clearly.

Note:
A faint beat will be heard at 52.000 MHz. This is normal
and is in no way an indication of trouble.

4.1.1 RIT Control

By using the WT control (Receiver Incremental Tuning), the
receive frequency can be shifted by about :t 1 kHz without
changing the transmit frequency. if the frequency of the
the station you are working changes, your receive frequen-
cy can be reset by turning the RIT switch ON and adjusting
the RlT control. Adjusting the control clockwise increases
the frequency and vice versa. The RIT shift can be checked

When first calling another station, the RIT should be OFF.
otherwise your transmit and receive frequencies will not
coincide.

4.1.2 NB Switch

The TS-660 has a sophisticated noise blanker designed to
reduce ignition-type pulse noise. The noise blanker is par-
ticularly important for mobile operation. When necessary,
activate the noisevblanker by depressing the NB switch 0N.

4.1.3 SOL (Squelch) Control

To eliminate noise at no-signal condition, turn the SQL
control clockwise until the noise disappears (normally
threshold point).

By so doing. the sound from the speaker is heard only when
the signal from your working station is received.

if the signal is weak or fades during mobile operation, read»
just the squelch for the clearest reception.

(The squelch functions on all modes, FM. 588, CW and
AM; however, the squelch level is slightly varied depending
on the mode of operation.)

Note that excessive turning the RF control counterclock-
wise disables the squelch function.
