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

(a) USB MODE (14 MHz and above)
Adjust the IF SHIFT control in the (+) direction and lower
frequencies are cut. Adjust the control in the (-) direction
and high frequencies are cut.
(b) LSB MODE (7 MHz and below)
Adjust the control in the (+) direction and higher frequen-
cies are cut. Adjust the control in the (-) direction and low
frequencies are cut.
(c) CW MODE
By using the IF SHIFT in conjunction with the RIT, tone
quality can be adjusted.
(7) NARROW SWITCH
In the NARROW position without optional filters no sig-
nals are received. Optional filters (CW: YK-88C,
YK-88CN, SSB: YK-88SN) for NARROW operation are
available for improved radio interference rejection. Any
two filters can be used according to your application.
When two CW filters, YK-88C and YK-88CN are used, the
WIDE position in CW mode is 0.5 kHz.
(8) NOISE BLANKER (NB)
For pulse type noise, such as generated by automotive ig-
nition systems, turn the NB switch ON. Adjusting the NB
LEVEL control varies the blanker's threshold, eliminating
even low level noises.
If high level signal or noise is present on an adjacent fre-
quency, do not use excessive NB threshold LEVEL as it
may distort the received signal.
If you are operating near other strong signals, use the RF
ATT along with the noise blanker level control.
4.3 TRANSMISSION (I)
This section covers adjustment of the transceiver for
transmission.
Refer to Fig. 4-1 for initial transmitter switch settings. Set
the main tuning to the desired operating frequency. (Refer
to Table 4-1 for a summary of the following.)
CAUTION:

. Turn POWER and HEATER Switches ON.
. Place the MODE switch to SSB, METER switch to Ip.
4. Place the STAND-BY switch to SEND and adjust bias to
60 mA (TS-530SP) or 30 mA (TS-530D) with the BIAS
control on the rear panel, Fig. 4-7.
CAUTION:
mA (TS-530D) do not leave the stand-by switch on for
more than a few seconds. Excessive plate current shor-
tens the life of the final tubes.
WN
DO NOT turn the BANDSWITCH while the transceiver is in
transmit mode.
