Variable Coil Tuning

Hi All,

	I ran some numbers today on how varying the distance between two top
terminals would affect secondary tuning.  By varying the distance 12 inches
I got a frequency tuning range of 11.5% !!  I am now thinking that having
dual terminals and having some motor deal that will vary the distance
remotely is a very good way to accomplish the remote tuning function.  This
eliminates the relays (thanks for all the great ides there everyone!!) and
makes things fairly simple.  Many thanks to Gary Lau for this idea!   There
seems to be great promise in this approach.
