2001 VERTEX STANDARD CO., LTD. Printed in Japan.
The Vertex Standard VXA-150 ProV is a compact, stylish, solid hand-held transceiver providing commu-
nication (transmit and receive) capability on the International Aircraft Communication Band ("COM" band:
118 ~ 136.975 MHz), and it additionally provides receive on the "NAV" band (108 ~ 117.975 MHz).
The VXA-150 includes our exclusive two-mode display with upright or inverted viewing when on your
belt, NOAA weather band monitoring, 8-character Alpha/Numeric Display, 50 Memory Channels, and 100
"Book Memory" Channels.
The following pages describe the Controls & Connectors, Accessories & Options, and Specification of the
VXA-150. With proper care and operation, the transceiver will provide many years of reliable communica-
tions.

Circuit Description TX/RX switch D1031 (MC2848), then amplified by Q1043 In the receive mode, VCO Q1023 oscillates between (2SC3356) and Q1047 (2SK2973), then applied to the 143.4 and 172.4 MHz. The VCO output is buffered by power amplifier Q1052 which increases the signal level Q1029 and Q1036, and applied to the prescaler section of up to 5 watts output power. - Page 13 Circuit Description Push-To-Talk Transmit Activation The PTT switch on the microphone is fed through the PTT controller, Q1002 (UMZ2N), to pin 41 of micropro- cessor Q1014, so that when the PTT switch is closed, pin 18 of Q1014 goes high. This signals the microprocessor to activate the TX/RX controller Q1017 (UMG2N), which cut off the receiver by disabling the 5 V supply bus at Q1020 (DTA143EU) which feeds the front-end, FM IF subsystem...

Page 14: Alignment
Alignment Required Test Equipment The VXA-150 is carefully aligned at the factory for the specified performance across the Aircraft and Weather ¦ Radio Tester with calibrated output level at 200 bands. Realignment should therefore not be necessary except in the event of a component failure. - Page 15 Increase the RF signal level to +15 dBµ (5.6 µV), then press the CHANNEL selector knob twice. r Press and hold the in the CHANNEL selector knob for 2 second to save all setting and exit.
