6.5 REMOTE CONTROL WIRING
Fig. 6-3 shows the REMOTE connector. This 7 pin DIN plug
can be used to control a linear amplifier or other external
accessories.
Kenwood linear amplifier TL-922 can be connected to this
unit with its remote cable. However, when a linear
amplifier other than the TL-922(A) is used, change the
connection as shown in Fig. 6-4.
This allows remote operation with the relay connected to
the terminal 7 of the DIN jack.
NOTE:
ALWAYS use shielded line for all connections.

@ OPERATION WITH A LINEAR AMPLIFIER
The TS-930S may be operated with any conventional
linear amplifier. which will accept up to approximately 125
watts RF drive, has a low current DC operated keying cir-
cuit, and returns approximately —-8~ —10 V DC ALC (aqd-
justable) back to the exciter. Please note that in order to
operate OSK (full break-in), the linear amplifier must also be
QSK capable.
For operation with a linear amplifier, refer to Fig. 6-3,
TS-930S internal wiring.
Pin 6 ALC input
Pin 2 Ground
Pin 4 Control line center conductor
Use shielded line for both ALC and RL (control line).
@ SSTV OR AFSK OPERATION
The TS-930S will adapt to slow scan television AFSK or
RTTY operation (besides the built-in FSK mode). For SSTV,
the only cabling required are connections between the
transceiver phone patch input and the camera output, and
between the patch output and the monitor input.
