Try this, buy some copper tape and add two narrow strips of copper tape to the top of the factory fix placing both across the entire part. I overlapped the second strip adding a bit of height (cut the tape to the exact width of the metal).I have found the same thing, Paul. Squeezing the front of the case reduces it. I have the factory fix and added some more tinfoil on top of that, but I guess I need more, too.
As a small business owner I can't agree with this. It's a Uniden problem, the warranty is through them, not the retailer. It's a subversion of the warranty.The only answer is to buy from somebody with a 30-day return policy and hope that the hum does not occur before that time runs out.
I know Paul still recovering I'm sure he is aware of it. I like to use a external speaker but it is crazy loud when the hum comes.Crap here we go again. Of course we all know the hum is still there. My hum started when I got the radio and has never stopped since with all the fixes in the world. Wonder if the hobbyist could final get a fix for it. Even if we have to solder crap together that would be great. I can't even use an external speaker since it drives me absolutely crazy anymore. I just hate this HUM noise. I want to get use to it but just can't stomach it.
It would be a better radio than great if that hum noise would go away. I guess Paul is still recovering so dealing with an SDS issues or firmware upgrades is out of the question until he returns
