The P25 Media Access Control (MAC) layer previously used a 500ms timer for the Adjacent Channel Status Query message. In dense trunked systems, this timer would fire before the base station could respond, forcing a retry and increasing voice setup latency to 1.8 seconds. The 2021 update changed the timer to a dynamic backoff – 300ms on first attempt, then 500ms, then 1000ms – reducing mean setup time to 380ms.
Hex-level evidence: Comparing v5.10.04 and v5.20.09, the offset 0x1C4F2 (P25 MAC timer constant) changed from 0x01F4 (500 dec) to a variable table at 0x1C4F8 with three values: 0x012C, 0x01F4, 0x03E8. 7010b radio firmware update 2021
