Chapter 3 Basic Theory of Operation
This chapter discusses the basic operational theory of the ASTRO APX 1000 radio. The ASTRO
APX 1000 radio, which is a single-band synthesized radio, is available in the following frequency
bands.
• VHF (136–174 MHz)
• UHF1 (380–470 MHz)
• UHF2 (450–520 MHz)
• 700/800 MHz (764–870 MHz).
All ASTRO APX 1000 radios are capable of analog operation (12.5 kHz or 25 kHz bandwidths),
ASTRO mode (digital) operation (12.5 kHz only), X2-TDMA mode (25 kHz only) and Phase 2 TDMA
mode (12.5 kHz only).
NOTE:
The APX 1000 M1.5, M2 and M3 radio support Global Positioning System (GPS) but do not
support Bluetooth, MACE and Accelerometer functions. As such, disregard all references to
the functions mentioned above in
“Chapter 3 Basic Theory of Operation”
