@ VFO-230 OR VFO-240 CONNECTION (Fig. 5-3)
Connect the VFO-230 or VFO-240 as shown in Fig. 5-3.
You will enjoy advanced operation including split-frequency
capability by combining a 20 Hz step digital VFO with five
memories (VFO-230).

™@ ACCESSORY CONNECTIONS
Fig. 5-4 shows the ACSY connector. This DIN plug can be
used for attaching a linear amplifier or other external
accessories to the transceiver. Always use shielded line for
all functions.
NOTE: — - —
ALWAYS use shielded line for all connections.
To ALC circuit
From STBY switch
(PTT circuit for foot switch)
From AF out (822) O

@ OPERATION WITH A LINEAR AMPLIFIER
Operation with a linear amplifier. Refer to Fig. 5-4,
TS-830S internal wiring.
Pin 6 ALC input
Connector metal shell Ground
Pin 2 Ground to connector metal shell and control line
braid.
Pin 4 Control line center conductor.
Use shielded line for both ALC and RL (control line).
@ SSTV OR AFSK OPERATION
The TS-830S will adapt very well to slow scan television or
AFSK RTTY operation. For SSTV, the only cabling required
are connections between the MIC connector of the TS-830S
and the camera output, and between the SPEAKER jack and
the monitor input
When transmitting, adjust the transmitter output so that fi-
nal input power is less than 100W (less than 125 mA Ip), or
for approximately 1/2 of normal output power. for AFSK,
connect the T.U. output to the MIC input, and speaker
output to the T.U. input.
@ PHONE PATCH OPERATION
The PC-1 Phone Patch can be used with the TS-830S.
Recommended settings are:
PC-1 RX Gain 4
TX Gain 4
Null as necessary
TS-830S Vox Gain 1
AF Gain 4
Mic Gain 5
Anti Vox Max
Most other phone patches will work satisfactorily without
any modification to the radio, requiring only an external
speaker connection, and that the Mic line be run through the
patch
For those operators who desire a Patch input similar to the
TS-520S or TS-820S, an input connection and terminal
must be added at the Mic input preamp circuit
Use a 100 k® resistor in series, with a 10 k to ground on
the input side of the 100 k{2 resistor. Use shielded line, and
connect as follows
Input 100K
