SECTION 5. OPERATING INSTRUCTIONS
5-1. OPERATING MODES
The TS-780 can be operated in the following modes by
using the MODE switch.
CW — Transmission and reception of Morse signals (A1).
FM — Transmission and reception of FM signals (F3).
USB — Upper side band transmission and reception (A3j).
USB is normally used on 144 and 430 MHz bands.
LSB — Lower side band transmission and reception (A3)j).
5-2. FM MODE
Reception
Set the knobs and switches as shown in Fig. 9, then
proceed as follows: When the shift switch is at SIMP (in
simplex operation), the mode switches FM-A and FM-B
operate in the same way so either of which may be used.
(Refer to 5-14).
1. Turn the POWER switch ON. The meter and digital
display are illuminated to indicate the power is on. The
digital display indicates 144.000 MHz and VFO A.
Select your operating frequency band by pressing the
DOWN (or UP) BAND switch. The frequency is shifted
band by band at each press of the DOWN (or UP)

Fig. 9 Pre-setting for Reception
Use of RIT Switch
The RIT (Receiver incremental Tuning) switch is used to
shift the receive frequency by about + 1.5 kHz without
affecting the transmit frequency (the indication of digital
display remains unchanged).
When the receive frequency is offset, turn on the RIT
switch (the RIT indicator will light) and turn the RIT control
so that the transceiver is tuned in the frequency.
Note that the receive frequency is offset from the
11
transmit frequency when the RIT switch is turned on, so
the switch must be set to OFF after QSO.
Use of RF GAIN Control
This is used to adjust the receiver RF stage gain. Normal-
ly, leave it fully clockwise. for a very strong incoming
signal, turn it counterclockwise. If there is a strong signal in
the vicinity of your operating frequency, lower the RF gain
to reduce intermodulation interference.
