LPD Encryption - Partial
Finally got a read on this one.
First to define what Longmont PD has in mind: You can expect to see all talkgroups with the exception of 'Channel 1' (9515) to be encrypted. AFAIK, that will INCLUDE 'Channel 2' (9516), though I cannot confirm this. Though the City moves at a glacial pace on many things, I'd expect this to happen sooner rather than later.
Now to the backstory:
Some have lobbied to encrypt 9515 as well. The primary reason for this is the peculiar way Longmont handles 'hot' events. All other agencies with which I've been familiar will take a serious or sensitive incident/event that develops on the primary dispatch channel to a secondary or tac channel, leaving normal traffic to the primary channel. Longmont is quite different in that regard. If a situation begins to develop on Channel 1, they will retain the escalating situation exclusively on Channel 1 (aka Code 3) and move all normal traffic to Channel 2. For that reason, some at LPD would prefer that Channel 1 also be encrypted. So far, management has resisted this. However, one wonders if they will also then change their policy regarding how they handle emerging situations and whether, like every other agency with which I am familiar, they will start to move the traffic for such things to an optional channel, leaving the primary dispatch channel for regular business.
Another issue (that it turns out they were aware of) has been the issue of encryption (or should I say, frequent lack of it) on TAC1, and even when TAC1 DTRS is encrypted, the clear signal being available on 151.22 VHF. Don't expect to see that last, either.
