You and everyone (including Uniden) who buys a SDS200 and implements my "Hum Fix" are most welcome!
Enjoy!

I have the 100 and 200 (had 2 200s but sold one to someone here) and the only issue I ever had with any of them was the battery latch on my 100 which I broke myself being careless. No hums. No cold solder joints. No vhf/uhf reception issues. Never had to do the hum fix or mitigation install. I am considering buying another 200 now that I have room on the desk for it. Hoping my luck holds out 
But, then again, maybe the hum is there and I just don't hear it. I traveled the world for years standing next to a Peavey bass amplifier stack and I know my hearing is damaged. Nowdays when I hit a low E I feel a void and a tremble deep down in my right ear that is quite bothersome. So, maybe I inadvertently developed a 'hum filter' that works for me lol. Who knows.

So then as an alternative fix for the hum, you'd recommend blowing your eardrums out?

Not that unusual of a thought... It might not be the first case of a professional musician not being annoyed by the humSo then as an alternative fix for the hum, you'd recommend blowing your eardrums out?
🤣🤣🤣Last I heard yes they are. Never heard anything to the contrary. No changes or corrections in manufacturing has been authorized or implemented by Uniden, other than the infamous 'WEDGE"! However it seems most of them shipping recently are without problems of the past, but that's no guarantee they won;t magically appear when you least expect it. In other words it's still a crap-shoot!

The hum only happens when I don't know the words har-har
I think the SDS200 “potential hum“ should be nicknamed “The Dynamo Hum”Want to avoid the potential hum of the SDS200?
Buy a SDS100.
Problem solved.
You're welcome.
Is there a thread about how to read the serial number to determine when the SDS200 was made? I getting mine on in a couple of days.As I had discussed in a recent thread, I got my second SDS 200 from Bearcat Warehouse and it was the first batch post covid shortage where they could not be obtained at all and I was amazed to see even with an external speaker I had to really put my ear up against the speaker and press hard to hear that familiar sound. I was impressed.
After about a month, the hum returned as it was on my first unit. Serial number indicates it's unit 1089 made in 2020 in Vietnam. If I am just listening to p25 Phase 2 it is just a whining sound but if I scan the P2 system with a few conventional items then It would be the whine and then a rolling digital sound. If I unplug the speaker I can not hear it through the speaker on the bottom of the radio unless I get really close.
Now that we have, a UPM who has been made aware of the StaticDischarge permanent repair, there should be no excuse for this to continue. I have also recommended a repair campaign so as to get this behind us. I'm sure they would sell more radios and the question about the hum would no longer be asked over and over again by prospective owners.

Look for the 12 digit Serial No. on the back of the scanner on the Uniden America Corporation label.
The single digit after the Z is the date code, for example.... 384Z9800xxxx is the 12 digit serial number... in this case the "9" = 2019.
A "0" would be 2020 etc.
On the back of the SDS200 box, look for the abbreviated 8 digit serial number (S/N) on one of the bar code labels, for example.... 9800xxxx. The first digit there is the date code.
The last 4 digits are believed to be the sequential production number of the unit within the year indicated, but not directly corresponding to a date within that year.

Oh GOD! mine are 8's
Thank you so much!
Has anyone experienced loss of audio? After I plugged in a speaker system I used with my BCD536HP (replaced with the SDS), the radio's audio cuts out after 90 mins or so. Turn the radio off and back on, audio returns only to do it again. So the simple solution was to unplug the speakers. That worked for 32 hours and a loss of audio again. Once again turn the radio off and on and audio returns.
This is a brand new SDS200 purchased in the last two weeks.
I'd put my BCD536HP back in service, except I sent to Uniden for repair of a very dim display.
Frustrating to say the least.

Off topic. This thread is about the SDS200, you might want to start a new thread to avoid confusion.

The external speaker are probably of a lower impedance that requires higher ampere and the problem will occure sooner. It's probably a safety function in the speaker amplifier that trips, either by temperature or a too high current, but are tripping at a much lower level than it should.

Wasn't there a thread here someplace where someone sent his 200 radio back to Uniden with whatever current problem existed (maybe the hum), and Uniden sent it back, unrepaired, saying it works the same way as all the current versions being shipped, or words to that effect?
Apparently, Uniden has decided that "scanners" are becoming a product that they can no longer put anymore money or effort into, in that there are more and more restrictions coming about (other than encryption, like proprietary systems, etc.) and the cost of development outweighs any potential profit to be made.
After all, just how much can they charge for a scanner before the final sale price is really prohibited to the casual "hobbyist" buyer?
