VXA-300 Operating Manual
Introduction
The Vertex Standard VXA-300 is a compact, stylish, solid hand-held transceiver providing
communication (transmit and receive) capability on the International Aircraft Communication
Band ("COM" band: 118 ~ 136.975 MHz), and it additionally provides VOR and CDI
navigation features on the "NAV" band (108 ~ 117.975 MHz). What's more, it also is
receiving on the Amateur Radio 144 MHz band.
The VXA-300 provides a 36-mm diameter Loudspeaker which outputs the 0.8 Watts audio
power from the internal speaker, and it also provides an 8.33 kHz synthesize step for the
newly narrow band channel plan.
The VXA-300 includes Temperature and Supply Voltage display with our exclusive Omni-
Glow
TM
display back-light for minimal degradation of your night vision, NOAA weather band
monitoring, 8-character Alpha/Numeric Display, 150 Memory Channels, and 100 "Book
Memory" Channels.
We recommend that you read this manual in its entirety, so as to understand the many
features of the VXA-300 completely. Keep this manual handy, so you may use it for
reference.
NOTE: The VXA-300's VOR and CDI Navigation features are supplemental aids to
navigation only, and are not intended to be a substitute for accurate (primary) VOR/CDI or
landing service equipment.
