I am trying to research the full signal specs for the Motorola Project (P) 25 "Astro" public safety trunk radio transceivers. This is the US version of TETRA.
As far as I can find out, for phase 2, the carrier is 800MHz with C4FM at 2.88KHz and a channel bandwidth of 6.25KHz.
Can anyone confirm this or provide more complete information of the makeup of this signal?
