A dipole has two elements. An end-fed half-wave is a monopole. One element.

Correct.
Fan dipoles work because the resonant 1/4-wave elements are lower impedance
than the non-resonant elements, so they get the majority of the power. A neat
trick, really.
The LNR End-Fedz antennas use traps. They appear to work just fine.

Looking at the FTP site, 1.45 is beta software. 1.39 is the latest
production release.
If it is working OK, staying with 1.45 should be OK. The file
archive was made on July 13th, so it probably is not badly
broken.

Just searched for OFS in the KX3 manual and I don’t see it ever defined. From
context, I believe it is short for “Offset”. I think you have found a bug in
the manual. It should be explained.

Elecraft does that for you. All the other options are exactly the same whether

These days, the source code matters as much as the schematic. Want to find the

Capacitors should usually have less loss than inductors. This is not true for
manual turners with polyvaricons. Those are fairly lossy capacitors.

was “Analog Filter Design” by
M. E. Van Valkenburg. Filters are designed by computer now, but the
math should be pretty much the same.

<http://dea.unsj.edu.ar/sredes/Biblioauxi/260360960-Analogue-Filter-Design.pdf&
Analog filters have phase delay. That would be stronger with a narrower filter.
Also, the on-off CW signal has sidebands (the harmonics of the square wave).
Maybe a narrower filter sounds “softer”? I have no idea what “full-bodied CW”
means, of course.
