You're right KXCI is a very interesting little regional/community station. 
Yes it is, KXCI is also a non-commercial, community based station staffed by volunteers, some who have been on air for over 20 years. KXCI's history is also very interesting. I listened to the "Big Broadcast" waiting (and waiting) for the music to start, after a 3 week evolution of sound us loyal listeners were rewarded with unique and constantly entertaining programing.
Here is a brief history of KXCI from the Wayback Machine:
Legend has it that KXCI got its start 32 years ago in a smoky bar in Nogales. Three friends, Paul Bear, Roger Greer* and Frank Milan were downing Tequilas and lamenting the lack of alternative radio in Tucson.
Some eight years later the three visionaries and a host of other volunteers were ready for KXCI's first transmission. During a three week FCC regulated engineering test period that began on November 15, Community launched creative broadcasting in Tucson with "The Big Broadcast of 1983." Never shy of unique and sometimes provocative programming, KXCI's DJs put together a schedule of programming that chronicled the evolution of sound. The Big Broadcast began "with the very first sounds thought to be created on earth," recalls Matt Finstrom. A tape loop of ocean sounds ran for nearly a week, followed by sounds of birds, animals and wind blowing through desert plants. Succeeding programs in the evolution of sound included primitive man made percussion and acoustic instrument performances, Gregorian chants, folk music, jazz and early rock 'n roll up to the current alternatives of 1983.
Regular programming began on Tuesday morning, December 6, 1983 when Robert Evans introduced the first "Morning Meditation" program. (That program recently evolved into "Brain Waves."). "Morning Meditation" was followed by another new concept, the "Music Mix." After 24 years KXCI's "Music Mix" is still designed to blend the world's musical forms and, in the process, demonstrate the beauty of cultural diversity. Recently KXCI added news segments to the schedule along with public affairs, blues, gospel, folk, electronica, rounding out the evening, late night and weekend schedule much like they did in the early years.
A constant flux of personalities, ideas and controversies have made KXCI's first 24 years of history colorful to say the least. Voted Best Radio Station for Music by the readers of the Tucson Weekly for 15 years in a row, KXCI is community radio at its finest.
*Roger Greer does not drink alcoholic beverages. So much for "Legends of community radio."
