VX-5500U Alignment
The VX-5500 has been carefully aligned at the factory for the specified performance across the frequency
range specified for each version.
Realignment should therefore not be necessary except in the event of a component failure, or alteration of
version. All component replacement

CTCSS Modulation Level
Select band center frequency channel, with 151.4 Hz CTCSS encode, and reduce the AF generator
injection to zero.
Key the transmitter and adjust by control commands for CTCSS deviation from the computer for 0.7 kHz ±
0.05 kHz deviation as indicated on the deviation meter.
