Of course, they don't realise that link  coupling IS a transformer. But 
wait - there is no TOROID - this is the 21st century, remember?

Both my homebrew transmitters use  link coupling in the exciter stages, 
the PA stage and the antenna tuner. The swinging link in the rf driver 
stage is what I use to adjust grid drive, and the one in the final 
adjusts antenna  coupling. OWL all the way, not a sprig of coax anywhere 
in the entire system between the rf final plate and the antenna 
radiating element.

So-o-o twentieth century!

And Geoff, I solved your problem more than 20 years ago when I had the 
external shack, formerly a one-room school building, moved onto the 
property. All the radio stuff is gone from the room in the house, except 
for some antique BC receivers. It's now the computer room, and my wife 
does her quilting and sewing there whenever she actually works on it, 
and it serves as a guest bedroom.

But we still call it the radio room.
