ADJUSTMENT
Adjustment No. Adjustment Condition & Tuning Value Ref. No. CK. Point
Checking AF Output 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.
Over
AF Output More than 0.35W 0.35W
@ 8 ohm
load
Checking RX S/N 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 Over 40dB
NARROW More than 34 dB Over 34dB
Checking Howling 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.
Checking Maximum While still in the AF output check status,
RX Current rotate the volume control clockwise to obtain
the maximum AF output. Check that the
current consumption at this time is as the
value below.
Max. RX Current Less than 300 mA Less than PWR Con
300mA
