I drive through I-80 pretty often, listen to NHP as I go. I notice that most radio traffic is simulcast across many sites/repeaters throughout the entire dispatch area, as I can sometimes hear a trooper making a stop at a given mile post which may be as much as 150 miles from my location.
However, I also notice that oftentimes I can hear the dispatch and initial call from a trooper making a stop, but don't always hear the secondary call (even doing a hold on the talkgroup and closest site). Took me awhile to figure this out, but my guess is that "sometimes" the system only uses the site closest to the trooper, and momentarily does not simulcast. I'm not sure if this is by design, but I've had it happen enough times to know it was not some anomaly.
In a routine stop the following occurs over the radio:
1) Trooper makes initial call, his ID followed by '10-6' (traffic stop)
2) Dispatch responds with acknowledge
3) Trooper then responds with location and license plate and make/model/car color.
4) Dispatch acknowledges
Its the step 3 that is missing from some of the broadcasts. I'm guessing the system does this for optimization purposes?
