That's fine, I was mostly commenting on the advise to get rid of the NES RF switch and buy a new aftermarket connector because apparently the NES RF switch would somehow be incompatible. It's basically a regular cable, it doesn't convert any signal so it should work fine. There's only problems if the switchbox is wearing out, then I can see a reason to use something else.

The Famicom should work on either channel 95 or 96, did you try 96 too? Just set the Famicom to channel 2 on the back and try 96 on your TV. By the way, how old is your TV?
