High level SSB transmitter; and old dream come true.
« on: December 10, 2019, 0459 UTC »
Some guys finally figured out how to do this with modern parts.  They claim 80+% efficiency @ 500W PEP out, 160-10 meters.

I am on their list of beta testers. So far it's been crickets since early June.

I understand the challenges of small teams and hardware development, but updates would be nice.

I'm also on the Beta test list and have heard nothing. Still its an exciting project if it really works. Wish them luck.
