Looking to purchase a digital scanner and I'm not very scanner savvy which is my reason for looking at the HP series due to its simplicity. I understand the HP2 can monitor Phase 2 while the HP1 cannot. My question is, how long will Phase 1 (which is what most of my local agencies have recently switched to) last and be functional on a HP1? Will these agencies be switching to Phase 2 soon making the HP1 useless and a pointless purchase? I'm not quite clear on the Phase 1 and 2 radio systems. Thanks in advance.
