TRANSMIT RF /IF TRAN SFORMER
ALIGNM ENT
( 1 ) Conne ct a dummy load to the antenna j ack ,
and conne ct an audio signal generator to the
microphone input . Tune up the transmitter
at MHz, and adjust the audio generator
1 4 . 2
output for approxim ately 5 0 watts output
into the dummy load , single-tone, SSB mode.
Peak T 1 04 (RF UNIT) for m aximum power
(2)
output .
(3) Peak T4o 1 - T4o3 and T4 os (IF UNIT) for
maximum power output . Swit ch the RF
processor on , and adjust the COMP LEVEL
control . for approxim ately 5 0 watts output .
Peak T404 for m aximum power output .
RECEIVER RF /IF /NB TRANSFORMER
ALIGNMENT
( 1 ) Tune in the m arker generator signal at
MHz, with a dummy load connected to the
antenna j ack. Peak the preselector for m axi­
mum S-meter indication.
(2) Peak T 1 02 (RF UNIT) for maximum S-m eter
indication .
( 3 )
Peak T40 6 - T4 1 1 and T4 1 3 - T4 1 s for maximum
S-meter indication.
Connect the RF probe of a VTVM to the
(4)
collector o f Q202 (NB-FIX UNIT) . Reduce the
RF GAIN control somewhat , and tune T2o 1
and T 202 for a dip i n the VTVM indicatio n .
If no dip is observed , reduce the RF GAIN
control further.
