My belief is, there aren't any current scanners that reliably do DMR. Whistlers use a method that is not proper trunktracking, and Unidens purport (try) to do proper trunktracking, but then they don't actually work and you miss transmissions. And I think the Unidens have a poor-sounding muffled/muted digital audio quality that sounds like there's too much bass and not enough treble.
So when it comes to DMR, we basically have no good options between the 2 brands. Next best thing is DSD+, but even that has unstable audio that drops out for breif moments.
