Transmitter Adjustments; Transmitting On Warc Bands - Kenwood TS-530SP Instruction Manual

gm ADJUSTMENT OF ANT AND MIX COILS
(RF UNIT)
The ANT and MIX coils are included in the coil pack unit.
Use the 25 kHz calibrator as a signal. Connect a 502
dummy load to terminate the receiver input. Set the
DRIVE control to 12 o'clock. Adjust the ANT and MIX
coils for maximum S meter deflection, following the fre-
quency table. Start with the 1.8 MHz band and then pro-
ceed to other bands. To adjust the 10m band, use only
28.8 MHz in the 28.5 MHz band.
mg ADJUSTMENT OF RECEIVE IF COILS
(RF AND IF UNITS)
Receive a marker signal using any frequency. Adjust the
DRIVE and the main tuning for maximum S meter de-
flection. Adjust T2 on the RF unit, L2, L5, L6, L7 and
L10 on the IF unit for maximum S meter indication. DO
NOT adjust L8.
m S METER ADJUSTMENT (IF UNIT)
Disconnect the antenna with the transceiver in receive
mode. Zero-point adjustment.
Adjust VR1 for meter pointer zero indication. If stan-
dard SIGNAL GENERATOR (SSG) is available, adjust
VR2 so the S-meter indicates "S-9", at 14.175 MHz for
a 40 dB (50 uV) signal.
6.4 TRANSMITTER ADJUSTMENTS
@ TRANSMITTER NEUTRALIZATION
(See Internal View Bottom)
The TS-530 requires neutralization every time the final
tubes are changed.
Tune up the TS-530 into a 50 ohm dummy load at
28.5 MHz for CW operation as described in Section
4. Set the SG switch to OFF and place a sensitive RF
milli-voltmeter across the dummy load. Flip the stand-by
switch to SEND and adjust TC1 (at the bottom of the final
section) for a minimum reading on the voltmeter. After the
final section is neutralized, flip the stand-by switch to REC
and slide the SG switch On.
A receiver tuned to 28.5 MHz works very well for
neutralizing if an RF voltmeter is not available. In-
stead of tuning for a minimum voltage, tune for a min-
imum S-meter reading.
NOTE:
Since the drive tube operates into a fixed load (the
finals) it is not always necessary to replace this tube
when replacing the finals.
CAUTION:
Neutralization of the final section should be carried
out with the chassis shield in place. Dangerous high
voltages are present in the final section when the
transceiver is turned on. Use an insulated tool to make
the adjustment.

@ TRANSMIT DRIVE COIL ADJUSTMENT
(RF UNIT)
The drive coils are part of the coil pack unit. Set the SG
switch on the rear panel to OFF and center the DRIVE con-
trol (12 o'clock). Set the METER switch to ALC and the
MODE switch to CW or TUNE.
With the standby switch in the SEND position, adjust the
drive coils for maximum ALC deflection for each band us-
ing the same frequency and in the same order as for ad-
justment of the ANT and MIX coils.
During adjustment, adjust the CAR control so there is just
enough injection to swing the ALC meter.
@ TRANSMIT IF COIL ADJUSTMENT (RF UNIT)
Using any frequency, place the transceiver in transmit
mode in the CW or TUNE position. Adjust T4 on the RF
unit for maximum ALC deflection.
m CARRIER BALANCE ADJUSTMENT (IF UNIT)
With a 502 dummy load connected to the ANT terminal,
adjust for maximum output at 14.175 MHz. Reduce mic
gain to zero. Set the transceiver in LSB mode and adjust
the RF METER control on the rear panel for maximum sen-
sitivity. The RF meter will deflect if the carrier is unba-
lanced. To balance the carrier, alternately adjust trimmer
TC1 and trimpot VR4 until the meter indicates minimum.
Switch to USB mode and if the pointer deflects, readjust
so the pointer deflects equally for both LSB and USB.
mg ADJUSTMENT OF SIDE TONE LEVEL (AF UNIT)
Adjust VR1 to your preference.
6.5 TRANSMITTING ON WARC BANDS
(Fig. 6-2) - (For TS-530SP shipped to the
USA, and for TS-530D)
As supplied, the TS-530 will receive but not transmit on
the 17 and 12 meter WARC bands. If transmit capability
is desired, a minor wiring change is required.
1. For 2 bands: Break the line between the RF unit
X44-1360-01, connector #6, Pin #1 (TOF terminal)
and AF unit X49-1150-00, connector #7, Pin #4
(TOF terminal).
2. Or, for individual Bands: On the RF unit X44-1360-01:
Band Remove (or Cut) Part
18 MHz D5
24.5 MHz D6
