Transmission (Ii) - Kenwood TS-530SP Instruction Manual

(1) SSB OPERATION
Tune the TS-530 as described in steps 1 through 9. Set
the MODE switch per Table 4-2, to USB or LSB and con-
nect a microphone to the MIC input.
NOTE:
International Amateur practice dictates using USB or LSB
as shown in Table 4-2.
To operate SSB, connect a microphone. (The Key and
CARRIER control have no effect in SSB mode.) Place the
MODE switch to SSB, METER switch to ALC. Adjust the
MIC gain control for an on-scale ALC reading on voice
peaks. (Disregard RF and Ip meter redings in SSB-they are
not accurate or relevant.)

@ PTT (Push to talk) OPERATION
By using a microphone equipped with a PTT switch, the
transceiver is ready for PTT operation. To key, depress the
PTT switch with the stand-by switch left in the REC posi-
tion.
NOTE: (For USA only)
1. Transmission is not possible with the BAND switch set to
AUX, 18 or 24.5.
2. Do not transmit when the BAND switch is set to AUX or is
midway between AUX and 1.5. Doing so will damage the
12BY7A driver tube.
4.4 TRANSMISSION (II)
To obtain maximum transmitter performance from your
TS-530 you should understand the proper operation of the
following controls and switches.

(1) SPEECH PROCESSOR
The speech processor in the TS-530 combines an audio
compression amplifier with changes in ALC time constant
to provide extra audio punch and to increase average SSB
output power, while suppressing sideband splatter. To
activate, turn on the PROC switch, and readjust mic gain.
Operated as described, distortion will be minimum. How-
ever, tone quality will be affected. It is therefore advis-
able to conduct normal operation with the processor dis-
abled.
When a high-output microphone is used, input overload
and distortion will result. To prevent this, use an attenua-
tor in the microphone circuit as shown below, or connect a
10 — 33 kQ resistor (depending on microphone used)
across the microphone input. ("Normal mic control set-
ting should be approximately 12 O'clock).
10k — 33 kQ (depending on microphone used.)

(2) VOX (Voice Operated Transmit) OPERATION
Adjust the transceiver as described in the previous para-
graph. Flip the VOX switch on and while speaking into the
microphone, increase the VOX GAIN control until the VOX
relay just operates. For VOX operation it is sometimes de-
sireable to close-talk the microphone to prevent back-
ground noises from tripping the transmitter.
Check that the ALC reading for voice peaks is still within
range on the meter. If necessary, adjust the MIC control
for proper ALC reading.
If the VOX circuit is activated by speaker output, adjust the
ANTI-VOX control (on the rear panel) as necessary for
proper VOX operation.
Do not use excessive VOX or ANTI VOX gain more than
necessary to control VOX operation. If the VOX circuit
transfers between words, or holds too long, adjust the re-
lease time constant by the DELAY control.
