I've heard three of these units now, all with hum. When I mentioned that I could hear the hum on one of them, the owner got angry at me and insisted there was no hum and that his was perfect. I left it at that.
I figure there must be some units without the hum since there are enough reports of such and you would think some of the retailers who say their sample units have no hum would know what they're talking about.
I also really wonder, though, if some people just can't hear it for whatever reason and consider their units hum-free. Like I mentioned in an earlier post, there are people who can't hear the hum on my own unit, which definitely has the hum. I've "auditioned" it for multiple people and it seems about half-and-half.
I wonder with all the electronic components and fans and such that we surround ourselves with these days, some listeners are able to simply ignore it as "white noise," not even considering it out of the ordinary. Bless them, if so, because I feel downright OCD and a little embarrassed for not being able to ignore it. I haven't turned the scanner on in almost two weeks now (since the "auditions") because of it.
All that being said, I hope the solution Uniden is working on solves the issue and really is feasible for us to carry out ourselves. I'm getting closer and closer to my return window closing and I'm trying to hold out but I'd be kidding myself if I said it didn't cause me more than a bit of anxiety for the price.
