    UHF2 (450–520 MHz) and 764–870 MHz frequency bands, and, VHF (136–174 MHz) and UHF2 (450–520 MHz) frequency bands. The ASTRO APX 7000 radio provides improved voice quality across more coverage area. The digital process, called embedded signaling, intermixes system signaling information with digital voice, resulting in improved system reliability and the capability of supporting a multitude of advanced features.

  • Page 31: Basic Maintenance

    In order to avoid operating outside the limits set by the FCC, we recommend that you align the ASTRO APX 7000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. Checking this parameter when the product is placed in service is especially important if the product has been in storage for a significant period of time (6 months or more) between being shipped from the factory and commissioned for service.

Digital (ASTRO) Mode of Operation In the ASTRO (digital) mode of operation, the transmitted or received signal is limited to a discrete set of frequency deviation levels. The receiver handles an ASTRO-mode signal identically to an analog-mode signal, up to the point where the DSP decodes the received data.
