I thought P25 predates 9/11? All those Astro Spectras and Astro Sabers surely predate 9/11? But 9/11 likely put in much more work into it and multi-band radio

  You're correct, and I should have fact-checked that rather than relying on my memory of what co-workers have said. Project 25 (P25) was started in 1988/1989; the first compliant radios came out in 2012. At some point after 9/11, it was mandated that all government radios purchased must support P25 (for interoperability), likely as a 9/11 Commission recommendation[1].
