Digital is the way to go. Supposedly all public services were going to be digital by 2013, and that hasn't happened but it is coming.
Not true.
The only requirement public safety agencies needed to make was to migrate to narrowband (12.5khz) from wideband (25khz) by January of 2013. Digital is purely an option, but not a requirement.
Most agencies that have gone digital are having major issues. The Washington State Patrol did just that, and last time I heard they were going back and forth between digital and analog while trying to get things right. Digital also doesn't work hardly at all in areas with mountains, hills, and large buildings unless you have LOTS of repeaters.
None of our counties fire, police, or ambulance agencies have plans to go digital anytime soon. Just getting the new narrowband analog equipment was a huge burden on their budgets, and as I mentioned above, our county sits in the foothills of the Cascade mountains, and analog narrowband is challenging most of the time, let alone trying to go digital.
Also, mentioned above was a Motorola scanner. No such thing. Some advanced hobbyists are buying older Motorola two way radios, and having them programmed to receive only, and using them like a scanner. They do work well for that purpose, and any older radio will receive narrowband just fine. They just cannot transmit legally, because they don't meet the 12.5khz maximum spacing requirement.
As for scanners, I'm running a Bearcat BCT-15, and an older BC-760XLT at home. I also have an old Motorola GM-300 two way that is set up to receive only, and I use it to 'scan' the three main fire frequencies for my area. I have an Icom F-5021 in my vehicle for all public safety frequencies, and I have it scanning the main fire, PD and sheriff frequencies. I also have a Kenwood TM-V71A 2M/70cm dual band 'ham' radio that I can monitor public safety with, but it mainly does ham duty. I'm a member of a couple of different public safety agencies, so I also had to upgrade my two way to meet the 2013 narrowband requirements.
