Does anybody who heard the test signal know for certain that the
modulation was that being proposed? Perhaps they were just testing a new

It looks to me like this is another new format, requiring the purchase of
new receivers from a sole source supplier who has probably got the whole
thing wrapped up in patents...  hence another government sanctioned
monopoly with commensurate prices.
