SBE SB-36 OPERATION MANUAL
4.2.6 Place the MODE switch to the TUNE position.
4.2.7 Place the VOX/REC-PTT/SEND switch to the SEND position.
4.2.8 Advance the MIG Gain Control slightly while tuning the PRESELECT control for
maximum indication on the meter.
CAUTION: Do not exceed 300-400 mA of plate current until final amplifier
tuning and load control have been properly adjusted.
4.2.9 Rotate the PLATE tuning control for minimum or dip indication on
the IP reading. When dip is obtained, advance the MIC Gain Control
to produce a 300-400 mA indication on the meter.
4.2.10 Place the METER switch in the RF position.
4.2.11 Rotate the LOAD control for maximum meter indication. Use the MIC Gain
Control as necessary to keep the maximum meter indication below 600-700
mA indication on the meter. Tune both the PLATE Tuning Control and LOAD
control to obtain Maximum indication on the meter.
4.2.12 Place the VOX/REC-PTT /SEND switch to the REC-PTT position. Rotate the
MODE switch to either Upper or Lower Sideband position.
4.2.13 Place the METER switch in the IP position. Press the push-to-talk button on the
microphone and, while speaking into the microphone in a normal tone of voice,
adjust the microphone gain control for an average IP indication of 350-400
milliamps.
4.2.14 Place the METER switch in the ALC position. The meter will indicate nearly full
scale deflection. Adjust the ALC potentiometer (located on the rear panel of the
radio) so that on voice peaks, a slightly downward indication is obtained on the
meter. This will indicate that the ALC is functioning properly.
4.2.15 The METER switch may now be placed in the RF position to indicate relative
transmitter power output.
4. 3 CW OPERATION
4.3.1 Perform the steps outlined in sterns 4.2.1 through 4.2.15.
4.3.2 Place the VOX/REC-PTT/SEND switch to the VOX position.
4.3.3 Rotate the MODE switch to the CW position.
4.3.4 Connect a key to the KEY jack located on the rear panel of the
transceiver.
4.3.5 Depress the key and adjust the VOX SENSE CONTROL on the rear
panel so that the transmitter keys on. It may be also necessary to adjust the
ANTI-VOX potentiometer on the rear panel of the unit.
