Hi Andy,
  Thank you for showing of IEEPaper.
Yes, this is a variation of Hell system. But it's a different
implementation.
This unit is easy to be moved one place to another and use a DDS chip.
  Our sheme is a same Sequential Multi Tone using 0.125Hz differencial
frequencies. Total band-width is 1.125Hz. The image is not one to one
scan character as looked 7 dots in the height.
  I recommend to test this unit in 137kHz band in a conjunction with a
QRSS viewer.
