ATR 600 VHF
Communications Transceiver
INTRODUCTION
The ATR 600 COM Transceiver consists electrically of five
sections: Receiver transmitter board, AF Stage board,
Antenna board, display circuitry, and the microprocessor
board. The ATR 600 operates at 14VDC and features typi-
cal 6 Watts of transmitter power. It can also be operated
down to 9VDC with reduced RF power (emergency opera-
tion).
The ATR 600 has 25KHz receiver selectivity, and operating
ranges of 118. 000 to 136. 975 MHz. It is designed as a
single block unit with 57 mm diameter for instrument panel
or console mounting. The ATR 600 has the capability of
programming up to 100 memory channel frequencies for
later recall. Each frequency can be given a name of 8
characters.
The unit also has the capability to store a data base for the
whole of Europe. A fast access method enables one to find
quicly any frequency by name. The data base is an add on
feature and not a basic function of the ATR-600. If it is not
installed or it has been erased by a special setup the ATR-
600 operates like any standard COM radio using an active
and stand by display pattern. The only additional feature is
the user memory and the possibility of adding names.
To prevent accidental long term transmission the transmitter
automatically turns off after two minutes (for example, when
a TX button becomes stuck ON).
