So I've read every post in this section, and am wondering if we can get a review of things. Firstly let me say that I live in a state that's not legal, but I can say that any neighbor of mine that might have a problem with cable, would NEVER even think of something like a ballast causing the problem. I personally grow, but in past when I've had issues with internet(not running any lights at time), not even myself, a grower, thought about a neighbor of mine growing. Not sure that makes total sense, but I'm trying to gauge why, even if u have some slight RF issues, it would be a problem? Obviously you don't want un-invited people knocking on your door. But if the cable guy is the worst I'd see, I'm not very worried. I have a couple NextGen's that I'm gonna run this round but haven't tested yet. So I'm curious what are my main concerns if I DO have an RF problem? And how could I get into any legal trouble(short of letting someone into my place and them finding my room, which I probably wouldn't do anyway)? Seems like almost an irrational fear after reading all of this. If the fear is only that my neighbors or myself might have some internet or cable issues, then I'm not very worried at all. Obviously if you drop hundreds on equipment that you can't use, that would suck. Maybe I'm reading this from the wrong point of view, but it seemed like the thread was warning that if others are interfered with, I might run into trouble with the law? And lastly, can someone explain again the frequencies that are probably ok, and the ones that I might have to worry about? Thx everyone, good info. Just trying to make sense of all of it. ;)
