Jan, I read the entire article by WA1Q1X. It's very interesting but
doesn't change my mind. One of the major problems that I see... and why
it could never replace external amplifier blocks such as our SkyWave
amplifier is that this digital system is high level modulated. This
does not lend itself to being added into an existing tranciever
system... like CB or Ham. This design is something that would have to
be incorporated inside the transmitter where a seperate audio signal is
available.
