To me the biggest problem with the Baofengs is the spurious emmisions. The spikes on other frequencies can cause repeaters some havoc. It's kind of like being a backpacker and leaving your trash behind. Just not nice. The Baofengs that do well on tests are fine.
That's part of it. Not to mention the crappy audio. I put one on my service monitor a few years back and it was about 450Hz off frequency, which is well outside the spec for any reputable radio, and made it sound even crappier than usual. Another I tested was over deviating, and another seemed really quiet.
My issue with the CCR's is that they can be a powerful tool that falls into the hands of those that don't understand how to responsibly use it. Kind of like CB's back in the 70's with "extra channels" and everyone assuming they needed a linear to talk to their friend 4 miles away. It just lead to the RF cesspool that CB became.
I agree the FCC messed up when mixing GMRS and FRS. The two never should have been placed on the same frequencies. But, you can't unring a bell. I do hope that the FCC might expand MURS to about ten frequencies, all narrow band. That would open up a lot of useful, unlicensed radio spectrum.
MURS was another one where the FCC let it get out of control and just gave up. It used to be that those were part 90 frequencies and getting suitable radios required working with a shop that knew what they were doing. Then the market got flooded with the low tier Motorola stuff that was sold in every Home Depot back in the 1990's. Anyone could go in and buy a radio. Users were supposed to apply for a license, but no one did. It got out of control with too many users on some channels and no one was bothering with the license or rules.
Probably a few other VHF itinerants that are worthy of being dumped into the MURS pool. And I was always a bit surprised that the FCC hasn't done the same with the UHF itinerants.
