ADJUSTMENT
Adjustment Condition & Tuning
Set the signal generator output level to
+60 dBu. The transceiver and SG connection
is the same as the squelch adjustment above.
Adjust the transceiver volume until the
distortion meter reads 5%.
Check that the AF output value at this point
as below.
AF Output More than 0.35W
Set the signal generator output level to
+60 dBu. Adjust the AF volume so that the
AF output is 50% of the rated value.
Check that the RX S/N in the bandwidth is
as the values below.
WIDE More than 40 dB
NARROW More than 34 dB
Set the signal generator output to +60 dBu
as in RX adjustment, and for non-modulation.
Next, set the internal speaker for operation,
and turn the AF volume up to maximum to
check that howling does not occur.
While still in the AF output check status,
rotate the volume control clockwise to obtain
the maximum AF output. Check that the
current consumption at this time is as the
value below.
