Introduction
This manual describes the circuit theory, program-
ming procedures, and alignment procedures for the
VX-900 VHF Portable Transceiver.
Much of the operating flexibility of the VX-900 is
derived from its versatile "Soft Key" front panel keys.
These keys may be configured for a number of op-
erating functions, as described in this manual.
Following the discussion of transceiver operation,
details regarding programming software, align-
ment, and maintenance will follow.
