The motorcycle ASTRO spectras are limited power - around 15 watts. The dash mount radios are usually ~50 watts (or lower on 800 MHz). The remote trunk mount radios are ~110 watts (or lower on 800 MHz). There area also several different "heads" that can me used on the ASTRO Spectra. W3, W5, W7, and W9 - all not compatible with regular analog spectras. The "W" series usually has "ASTRO" printed on the head somewhere.
The ASTRO spectra is being phased out. The XTL series (XTL 1500, 2500, 5000) will take the place of the ASTRO Spectra.
