Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.
We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.
If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I've spent a little more time with it and I've been able to reduce the noise (I'll quit calling it a hum because that's not really a good description) by about 90%. I took a video of what it sounded like initially and how it sounds by moving the plate all the way forward and applying modest downward pressure around the top left corner of the unit. I'll upload it if I can figure out how.
I'm just not brave enough to go beyond removing the upper and lower inner plates but it seems like it does indeed get much better when the top inner plate makes contact with the metal around the screen.

I removed the black metal housing sleeve and placed some thin foam padding I had laying around on top of the silver metal housing as close to the front of the radio as possible. It has helped reduce the speaker hum dramatically. Still could use some more, as when I push down with my finger in that area, the noise almost completely disappears.

Sounds like an internal component shielding and/or grounding issue. Not uncommon in digital and RF environments. Unfortunately, the real resolution may well be via design and/or component change. Basically, internal noise is getting into the receiver circuitry chain. Padding the audio would just be a mask. Firmware update may be able to address it via DSP filtering, but the real fix is hardware related. This is one reason why we see product revisions over time and is one of the pitfalls associated with being an early adopter.
Agreed...but it could still be a component QC issue as well. So far, seems to be a 50/50 crap shoot on units w/o this issue. I see some posturing that this noise is normal, which doesn't surprise me. Uniden didn't make any changes in their export transceivers that were affected by CW buffering caused by a design flaw. Ignoring a FLAGSHIP scanner? We'll see.
