MFD Frequencies?

[Mike(Mont)]

On another thread Tim said NMR frequencies have nothing to do with MFD. I just thought I would mention this here as a sort of disclaimer.

I also want to reinterate MFD is not exactly like a radio transmitter and receiver as many of the skeptics seem to imagine. However the signal line works, it somehow acts as an antenna. Why does it take time to build up? If it was just a radio signal reflection it would take no time. From what I know about resonance, it does not have to be exact--maybe this is why it takes some time to build.
