Transmission (I); Transmission - Kenwood TS-530S Instruction Manual

(6) NARROW SWITCH
In the NARROW position without optional filters no signals
are received. Optional filters (CW: YK-88C. YK-88CN. SSB:
YK-88SN) for NARROW operation are available for im-
proved 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.
(7) 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 s~gnal or noise is present on an adjacent
frequency, 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:
DO NOT turn the BANDSWITCH while the transceiver is in
transmit mode.

1. Connect a
5OQ
antenna for the band you will operate or a
dummy load. and connect a key. SWR must be 2: 1 or
better. The life of the final tubes is directly related to
the SWR of the antenna, and to the length of tuning
periods.
2. Turn POWER and HEATER Switches ON.
3 3 . Place the MODE switch to SSB, METER switch to Ip.
4. Place the SFAND-BY switch to SEND and adjust bias to
6 0 mA with the BIAS control on the rear panel, Fig. 4-
5.
CAUTION:
If the plate current is higher than 6 0 mA do not leave the
stand-by switch on for more than a few seconds. Excessive
plate current shortens the life of the final tubes.
