Did you purchase your SDS200 new or was it pre-owned?
Brand new from Uniden, roughly 3 months ago.
The "hum" issue seems to have been fixed. My SDS200 was built in late (I believe) 2020 and purchased a year ago. I have had zero hum issues and the radio is on about 14hrs a day.
Can you explain that a little more? I do not know much about electrical technicalities, but my 200 is plugged into a Tripp lite power strip that has a couple other things plugged into it, nothing crazy though. What do you mean by improperly shielded power supply and a "noisy" nearby electrical device?
I tried it and nothing changed, thanks for the suggestion though.
That's unfortunate, especially being how new it is. Should I send it in for repair under the warranty? Upon reading other threads, this issue appears to be recurring with many units, so if it's just gonna happen with every replacement unit I get, I'll just get used to it.
All kinds of things can cause a hum in electronics. Without going into a long winded post about inductance, impedence, grounding, filtering and so forth... A quick way to test is to take your radio to another location (friend's house, work or some such) with just the power supply and antenna and see if it still hums. Touch the antenna, does that increase or decrease the hum or do nothing.
Uniden is laughing all the way to the Bank.
