(9) 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.
NOTE:
If high level signal 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.
Power meter
Fig. 4-8 Testing with a Dummy Load or Power Meter
1. Connect a 502 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 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 with the BIAS control on the rear panel.
CAUTION: - ~ . ~
If the plate current is higher than 60 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.
e
(10)TONE CONTROL
Adjust this control to obtain desired tone quality.
4.3 TRANSMISSION (!)
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.
