TX Younger Unit: Signal from the VCO and Signal which is selected from
X701
to X705 and oscillated by Q706 in IF unit are mixed with balanced mixer
Q401
and Q402...
[The Younger Unit description just made me a little bit older...]
Counter Unit: The PLL IF is amplified by Q304 and then generated by
Q303 and
fed into IC304. This signal is divided in half by IC304. It is then
program-divided
by IC301 to produce an output of 25 KHz. On the other hand, X301 (10.24
MHz)
is oscillated by Q306, and fed into IC304...
[And that makes me feel oscillated and generated. On the other hand...]
...Q557 and Q558 are worked as protector circuit.
[Work it, baby, work it! ]
When the excessive power happens to be supplied in transmit or receive,
Q558 is automatically cut off...
Yep, excessive power, like shit, happens.]
THE 13-513 HAS BEEN FACTORY ALIGNED USING TECHNIQUES AND
TEST EQUIPMENTS NOT NORMALLY AVAILABLE TO THE SERVICE
TECHNICIAN.
Equipment required:
a) ...
b) Synchroscope (DC to more than 250 MHz)
[Also required: explanation of what the hell a synchroscope is!]
...and also adjust them so as to be within 20% of amplitude difference
in case
221 and 222MHz bands are switched over each other.
[But if they were switched under each other, THAT would be unnatural.]
Repeat the above step c) through e) adjustments repeatedly.
[And that was redundant redundantly.]
...13.8 volts controlled by APC or unlooked signal.
[If a signal happened in the forest, and was unlooked, would it
still make noise?]
