Those of us that have had them from day 1 of their release say different
This scanner actually went through some stages with identifiable flaws that were addressed by Uniden without much discussion on radio reference, they realized the problem and they fixed it. Not every radio was affected as with, the SDS 100 and csj.
The Uniden representative was a daily contributor to radio reference and took his share of abuse and kept on top of each tweaking that needed to be done with hardware and firmware. May he rest in peace as he passed in late December of 2019.
Of course there was never any details or serial numbers attached to various units with issues. It was not every unit.
The dark screen issues and clock issues with the x36 series was eventually dealt with with a repair campaign, you signed up and your radio was repaired for free, regardless of how long you had it.. something Uniden should have done with the csj and the rotary knob issue on the sds100.
They obviously didn't agree. Why should they, they are the only game in town.
I have no doubt that the 436, as it approaches end of life status, that's sold today, has all issues of the past resolved other than inability to handle certain simulcast systems. That's not the radio's fault😉
