[ARC5] the age old battle of modify or sanctify and the Demill dilemma

[D C *Mac* Macdonald]

I built a W2EWL "Cheap and Easy S.S.B." rig in 1962
while I was attending USAF Electronic Warfare Officer
school at Mather AFB, CA near Sacramento.

I got great carrier suppression, but didn't have either
the knowledge, skill, or test equipment to get the
unwanted sideband suppressed. I think I sold it to
one of the members of the R.A.M.S. (Radio Amateur
Mobile Society) club there in Sacramento.

I felt reasonably competent to then move to buy a
Hammarlund HX-50 SSB transmitter in 1963.

Good training and experience, for sure.

By the way, I believe that the current holder of
W2EWL knew the original holder.
