I checked the manual on the QRPme.com webpages and noticed it is at the Preliminary version.
The latest released version is 22 January 2019.? I'm sending a copy to Rex (I think I did...8^)).? In the meantime if anyone would like the updated version right away, I'd email a copy:1.74Mb.
Also, I have a copy of the 1969 patent for the "Broadband Directional Coupler" and I'll send that to Rex.
