Just don't expect a long life cycle. Astro 25 radios are becoming "teenagers" and already, EEPROM and "leaky cap" failures are plaguing them. The first gen Astro stuff is over TWO DECADES old for the most part, and thus, many of these subscribers saw hard lives being carried 12-16 hours a day with long hours of actual run time. The first things to fail are the EEPROMs which hold the internal and external codeplugs including the tuning partitions. While the chips are cheap (for now), it takes someone with skill and unmentionable tools (if one has a backup of the unspoken records) or complete retune/realign from scratch, both of which require way more tools, test equipment and skill set than one can obtain on a hobbyist forum.
That being said, have fun.
