No because the project emphasizes AM, an old spectrum-hog mode
which ought to have been retired about 1965.
Why? AM is a legal mode, with advantages and disadvantages.
AM is a relic, inefficient in it's use of spectrum, and inefficient in it=

of power (only half of the transmitted power contains intelligence and ha=

that half is discarded at the receiver!).
And they don't have no twin vfos or memories or autotuners and even
worse they don't have no ears at all . . WTF . .??!
One of the key elements of the spirit of experimentation in
something "different" is not being constrained by what is
considered electropolitically correct.
I don't know WTF the phrase "electropolitically correct" is even supposed=
to
mean.
Besides, the Class E technology can be adapted to
a variety of modes.
Yes, it certainly can. Which makes it all the more puzzling that they'd
showcase it with a doddering old mode like AM. Class E is technolog=
ically
interesting, and kind of "electro-sexy". Showcasing it in an "AM suit" is
equivalent to showcasing Jessica Simpson in a fully secured HAZMAT suit.
Incidentally, the technology is a little older than Jessica. See "Class-=

Yea verily, I heard about class E beaucoup years ago and Googled it,
found the link to that paper but since I'm not an IEEE member I wasn't
allowed access to it.
