The Vertex Standard VXA-210 Pilot 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 addi-
tionally provides VOR and CDI navigation features on the “NAV” band (108 ~ 117.975 MHz).
The VXA-210 includes Temperature display with our exclusive Omni-GlowTM display back-light for minimal degrada-
tion of your night vision, NOAA weather band monitoring, 8-character Alpha/Numeric Display, 50 Memory Channels, and
100 “Book Memory” Channels. And the optional Barometric Pressure Unit (SU-1) provides readout of barometric pressure,
altitude, and density altitude.
The following pages describe the Controls & Connectors, Accessories & Options, and Specification of the VXA-210.
With proper care and operation, the transceiver will provide many years of reliable communications.
