There are a few reasons including the fact that most units do not have the issue, and the metal tab solves most that do.
The user-added part was cost effective and issue-effective in most cases.
I was not part of that original discussion.
I too am disappointed that the solution I proposed was not done sooner, but complaining about it fixes nothing. I can only surmise that Paul was not aware of that or he believed that the tab was all that was necessary. I'm not going to speculate about what he knew or didn't know, or his motives.
Perhaps we do need to take early production units apart to check for issues like this. I'm sure management is not going to like me taking one apart, but if it finds an issue (unlikely from here forward) then maybe it is worth it.
I will address this with management again to see if there is a better solution to catch future production errors.
I swear there was a post here in the past few months where someone either had their SDS200 repaired by Uniden or it was a brand new purchase. I forget which but I think it was a new purchase.
Either way, that person opened up the radio to do the StaticDischarge mod and found that Uniden had added a new ground wire soldered to the visible side of the front board that ran to a case screw ground similar to the other ground wires.
I remember this as the OP had needed to do the mod on his older SDS200 but was surprised when he found the new ground wire that had been added in his new 200.
I never saw a reply post showing the point on the back of the front board where this new ground wire was attached so who knows. It sounded like this new ground wire provided the needed ground to the front board to eliminate that hum though.
What I don't know is if this was a Uniden fix or newly added ground wire or if he received a 200 that was really not new and had been modified by someone else that returned it.
The point was that the display board could be ground by adding a new ground strap wire to a ground point on the solder side of the board which could be done without removing anything but the covers to gain access to the back of the board.
It sounded good (and easy) if true but the OP never replied with any pictures to my knowledge so I never followed up on it any further. I'd already grounded my display board but found this info interesting.
I wish I could find that post about this. I guess it could have been a post on a groups.io message board also but I'm fairly certain it was here at RR.
