That Sutherland is a secretive guy as he doesn't explain his scalar device and how it works.... But from what I've gathered recently, it looks like a modified (or maybe not) radionics device that is connected to the F165 generator to send the freqs wirelessly, possibly like radio signals. Now I know that the wireless transmission is possible after having used quartz crystals for sending audio freqs to myself.
He charges way too much for his SC-1A, as radionics devices cost a lot less and many have audio inputs (RCAs or 3.5mm).
