Short answer no it's a two way radio for professionals not a scanner for hobby enthusiasts. Most first responders stay on a single channel usually for a event and only scan necessary channels while not on a active call. If you want more than 10 channels to scan buy a scanner.
This is misleading as the radios can scan 15+1 in conventional, but are limited to 10 in trunked (which can be a mix of trunked and conventional) . Have you seen how many trunked talk groups can be scanned with the APX radios? You think the APX 7000 and 8000 are designed for scanner enthusiasts? There are times professional users just want to hear more.
I keep my XTS2500 on the desk in the alarm room and scan 10 channels, but wish I could scan 12 on that radio.
It is simply a limit to how Motorola designed the software. You can scan 16 in conventional (15 + 1) and 10 in trunked.
On the other hand, public safety is generally not in a hurry to encrypt. Maybe on the law side, but on the Fire and EMS side, no. Why? Well if you're in an area where some departments are UHF, others are VHF, some still use low band and others are on 800 trunked, encrypting makes monitoring your neighbouring departments impossible. You ever meet someone in the Fire Service who didn't want to hear what was going on around them? Even on the law side, there is push back against encryption in areas where many frequencies bands are in use, with a mix of analog of digital, encryption in these areas costs lives rather than saves them.
