ALIGNMENT INSTRUCTIONS
(1) ALIGNMENT FOR FM FREQUENCY RANGE
a. Required Instruments
FM RF signal generator
SSVM
b. Alignment Procedure
Mode Adjustment Procedure
(1) Set the power switch to the ON position.
(2) Connect a SSVM to the TP5 and TP6.
(3) Connect the FM signal generator to the input terminal of the rod antenna
(TP1, TP2)
(4) Set the signal of the signal generator to the standard FM band, with frequency
deviation to 22.5 kHz modulation.
(5) With the tuning gang fully closed, set the signal generator to 87.35 MHz ±0.15
MHz and adjust L4 for a maximum reading on the SSVM.
(6) With the tuning gang fully open, set the signal generator to 108.25 MHz ±0.25
MHz and adjust VC3 for a maximum reading on the SSVM.
