Famicom Controller Causes RF Interference?

[Rockman]

I was using my original round-button Famicom connected to my TV through RF Out, and noticed something strange, yet interesting: if I turn on my Famicom while Controller 1 is in its holder, the screen seems to have these barely-noticeable rolling noise bars, however, if I hold the controller out and away from the system, the bars seemingly disappear. Is this a normal occurance, or is there something wrong with my controller/system?

interesting can you make a video ?
I think it is normal for RF to be sensitive to nearly anything, so do not worry

I could attempt to make a video, but can't guarantee I actually can. Also, i've learned two things from fiddling around with the system: First off, there is a pretty big difference in picture quality when I change the system from channel 95 to 96. Channel 95 seems to be the fuzziest, but has the least amount of audio crackles, whereas 96 has the best picture quality you'll get from RF, but the audio crackles are a bit louder. The other thing is that I had a Nintendo Wii right next to my Famicom, and I unplugged it to see if it had any effect on the interference, and sure enough, it did make a difference. However, controller 1 still seems to cause some interference.

do not worry it is normal, to make the sound clearer you have to turn those things very slowly all of them, when famicom is on and find the right spot.
