Looks like a revival is needed for 49MHz. Granted, 49MHz is plagued more by electrical and computer noises, but if I remember right, wireless mics started down there in 49MHz, where they shared space with walkie-talkies, cordless phones, baby monitors, and even stereo wireless headphones. Hmmmmmmmmmm, I see an opportunity to make out big here $$$$-wise. There's always loop holes somewhere, and in this case, 49MHz could be it, again. It's true, what's old can be new again. In a pinch, a 10 channel 1980's - 90's cordless phone can be modified to do just that, be a wireless mic, even a two-way intercom, with the 46MHz / 49MHz split. Can be done!!!
