Well I for one am part of the "everybody" and I never once thought there was any "magical potion" applied to these radios. I was fully aware of the "issues" and also the "fix" Uniden applied that as UPMan has stated "
mitigated to cause to become less harsh) the hum" (without the delusion of magic, lie or whatever..)
I also have stated that my "fixed" SDS200 does not appear to have said hum in any configuration ie: internal, external speaker or headphones at any volume level up to distortion.
Oh, and I haven't yet read anywhere in this thread where anybody else has had this so called "delusion of a magical change of design".
I can only assume you've not had enough coffee this morning?
