I had good luck with a TS-520se and an unamplified D-104 using an impedance
converter from one of Doug DeMaw's (W1FB) books. It was a simple FET and
a few other components. Mine was in a little box, but it could have been
just as easily built into the empty base.
I can't be more specific of the circuit, when I moved to Israel in in 1996,
2 boxes of books from about 60, were "lost". One was all my teach yourself
Hebrew tapes and books, and the other was almost all of my radio books.

The trouble with being a futurist is that when people get around to believing
you, it's too late. We lost. Google 2,000,000:Hams 0.
