Well, I got one myself, and tried the mod, but soon as I did it, the thing started making a loud screeching sound. It receives fine but this sound is now going on. I mean before people all say something it's like hey...It's a hobby. It's not like I'm going to use the radio for an fcc test. It's just more a thing to unlock the Easter eggs, so to speak, that come with the radio. If you're a responsible person, you probably don't even transmit on frequencies you're not supposed to. I don't. I don't think the act of doing the mod is against the law. It's just not to be an ass and don't mess with frequencies that are being used for other purposes. I can only speak for myself, everyone else...It's not any of my business. All that said, I wonder what the he'll I did to make the thing start squealing like that.
