PREMIX UNIT (PB- 1 96 2 )
The premix signal is produced at Q 3 0 3
a d ouble-b alanced mixer, where the premix local
signal from Q 6 0 1 - Q6 1 0 is mixed with the VFO or
crystal controlled 5 MHz signal . The premix output
frequen cies are shown in Table 3 . The premix
sign al is passed through b andpass filter T 3 0 1 - T 304 ,
and amplified by Q30 1
The amplified signal is then fed to the
(2SC373 ) .
RF UNIT, where the signal is further amplified
by Q 1 0 7 for delivery to the transmitter and receiver
mixers.
