Sorry, I do not quite understand ... The Uniden scanners do they scan DMR frequencies? That's right? What model do you indicate?
And from what I understand, do I have to pay to have the Uniden scanner updated to be able to scan DMR frequencies?
Uniden charges a fee for DMR, but Uniden scanners will track trunked DMR, while Whistlers do not. On a busy trunked DMR system, the Whistlers will give you random snippets of whatever talkgroups are active, but Unidens will allow you to lock on to a talkgroup and follow it even if the system changes the frequency in mid-conversation.
