I have been successful in monitoring new phase II talkgroups on the Asheville system with my '436. At least for the present, neither FD dispatch nor PD dispatch are encrypted. Not sure if that might change for PD. Hopefully, only sensitive operations might be encrypted and dispatch will remain open.
Apparently, some of the talkgroups on the new system (mostly non-public safety thus far) are still phase I since I am able to monitor them on my HP-1.
This is my first Phase 2 experience and I noticed that I was still receiving some Asheville transmissions on my Phase 1-only scanner. After reading up on Phase 2 systems, I discovered that Phase 1 radios can continue to be used on these new systems. Most probably to allow for gradual migration to Phase 2 operation.
According to what I read, it appears that any talkgroup that has any Phase 1 radio affiliated to it will continue to operate in Phase 1 mode. Only when ALL radios in a talkgroup are Phase 2 capable will that talkgroup operate in Phase 2 mode.
Thus, it appears as if certain groups can still continued to be monitored as standard P25 systems until all of the older radios are replaced with newer Phase 2 radios. And this information seems to be borne out by my recent listening.
