Oh Darth
You're right, I don't personally have any experience with those radios. My only experience with the quality of them is the 4 local hams that have all had issues with theirs. I've heard enough bad about them that I don't want to try one.
My issues with those radios are:
1) Full TX capability. I live across the street from a state park and I can't tell you how many times I've seen hikers using them illegally. I scan 2 meters pretty often while I'm at home and during the summer months I hear quite a bit of unlicensed FM activity on 144.000 and 146.000 MHz. More times than not they're using cheap radios. The few times I've questioned someone about the radios, they said they bought them from Amazon and didn't know they needed a license.
2) That brings me to number 2. Most of the online retailers of those radios market them as "two way radios." There's no mention that a license is needed to use them, and I've even seen some marketed in the FRS, Camping, Outdoor Electronics, Fishing, and Hiking sections. Those radios have opened up the flood gates for potential unlicensed interference in not only the ham bands, but also the public safety bands. Even on this forum there's been posts from people who have purchased them, punched in some random frequency, and are using them illegally.
Now sure, anyone can buy a modified ham rig and do the same thing, but with the cost of amateur gear not many hikers are buying Yaesu HT's. But at $30 each, the Boofungs make a very attractive priced radio.
3) I think they're terrible for ham radio - especially new hams. How many posts here have we seen someone new to the hobby that's excited to get on the air. They purchase a cheap China radio and can't figure out how to program it. That makes it very discouraging to the new ham, if they had just got an easier to program KenYaeCom radio they'd have a better experience and introduction to the hobby.
Let me ask you, since you're so defensive about these radios, what exactly do you like about these radios over the other name brands? Since you have no first hand experience with the big name brands, why do you defend cheap China radios if you don't know how much better a Yaesu or Kenwood is?
