Guide to ASTRO™ Digital Radios
XTS 3000™
Released in 1996, this was Motorola Inc.’s first Cosmo-series portable radio. It is compatible
with nearly all Jedi-series audio accessories, including speaker-mics, hirose adapters, key-loading cables,
3.5mm threaded earphone adapters and other surveillance accessories. (Desirable at the time because
of the MTS 2000™ popularity)
Figure 3.1 Motorola Inc.’s XTS 3000™ (Model III) with speaker-mic.
The XTS 3000™ comes in identical band-splits as the ASTRO Digital Saber™.
Unlike the ASTRO Digital Saber™, the XTS 3000™ does not have a vocon board. Instead, there are
four PC boards which make up the radio. They are: The Voice coder/decoder (vocoder), the controller,
the RF board and the optional encryption module.
