Fender is a traditional Milwaukee Summerfest Sponsor. I recently did a project that inventor Leo Fender worked on in the 1930s with harp amplifiers, before he developed electric guitars.

The fading problem is probably due to the connection of the resonant circuit to the antenna which in conjunction with changing conditions (moving in space, grabing it with hand...) shifts the resonant frequency due to the load/RLC changes, much better simple solution is using another RF gain stage just to separate the oscillator coil form these changing effects that pulls the frequency of resonant circuit all over the place...
You will get much stable frequency this way, other option (best) is PLL that will lock frequency to the quartz controlled reference (very stable)...
I think all pro wireless mics use that circuit...
