Front Panel - Kenwood TS-530S Instruction Manual

3.1 FRONT PANEL
The symbol after the part name indicates:
@: Active only during reception.
@:
Active only during transmission
No symbol: Always active
1.
PROC (SPEECH PROCESSOR) INDICATOR
@
This indicator, (light emitting diode), illuminates when the
PROC switch is turned ON.
2. VFO INDICATOR
The VFO indicator illuminates when the internal VFO
controls transceiver operation. The indicator is not lighted
during fixed channel or remote VFO operation.
3.
C A L INDICATOR
@
The CAL indicator illuminates when the CAL switch is turn-
ed ON.
4. RF ATT INDICATOR
@
This illuminates when the RF ATT is turned ON
5. METER
The meter monitors five different functions, depending on
METER s w i t c h p o s i t i o n . I n receive the meter i s
automatically an S-meter, and shows received signal
strength on a scale of 0 to 4 0 dB over S9. In transmit,
meter function depends on the position of the METER
switch. as described below. This is an average-responding
meter, NOT peak-reading.
6. VOX S W I T C H (T)
The VOX circuit is readied for voice operated transmit in
SSB or semi-break-in CW.
7. VOX G A I N (T)
This controls sensitivity of the VOX (Voice Operated
Transmit) circu~t.
8. N B S W I T C H
@
With the push switch IN, the noise blanker circuit turned
ON reducing pulse-type (ignition) noise. Power-line, radar,
QRM and atmospheric "white" noises will not operate the
blanker. The noise blanker circuit operating level is
adjustable by the noise blanker control.
9. N B LEVEL CONTROL
@
This control adjusts the noise blanker circuit operating level
according to receiving conditions or noise level.
lo.
AGC SWITCH
@
This controls the AGC (Automatic Gain Control) circuit:
..............
OFF AGC disabled (no AGC).
FAST
............
Normally used for CW operation.
SLOW
..........
Normally used for SSB operation.
11. METER S W I T C H
This determines the transmit meter function:
ALC (Automatic Level Control)
Monitors internal ALC voltage, or the ALC voltage
feedback from a linear amplifier operated in conjunction
with the TS-530s. For SSB operation the ALC reading
for voice peaks should be within the indicated ALC
range. ALC voltage adjustment is made with the MIC
control for SSB and with the CAR control for CW.
IP (Plate Current)
In this position the meter monitors final tube plate cur-
rent. The scale is calibrated from 0 to 3 5 0 ma.
(Output Power)
This monitors relative output power of the transceiver.
There is no meter scale for this position. Normally the
reading should be adjusted (with the RF METER
control) for a 2/3 scale reading.
( H ~ g h Voltage)
This position monitors the high voltage power supply.
The meter scale is calibrated from 0 to 10, indicating 0
to 1 0 0 0 volts.
STAND-BY S W I T C H
@
This two-position lever switch selects:
REC ............. The transceiver is receiving unless the
microphone PTT switch, or the VOX circuit is
activated.
...........
SEND
Locks the unit in transmit.
13. VOX DELAY CONTROL IT)
The DELAY control adjusts the hold t m e for VOX or break-in
CW operation. Adjust for individual preference.
14. CAR LEVEL CONTROL (TI
This controls carrier level during CW operation. Adjust the
CAR level so that the ALC meter points to the center of the
ALC zone. The ALC meter should not read beyond the ALC
zone.
