I thought I recalled a 4 band. That confused me. I'm not interested in just
the two, nor a used one. Maybe there's a chance the 4 band kit will come
back? Oh well.

There used to be a 4-band module, but it is discontinued. There doesn’t seem to
be any chance it will come back. These days if you want more bands, you can
either look at a KX1, KX3 or K2.

You are right about that.
The only part of the Kenwood "520 Line" my Dad didn't get was the SP-520.
He thought $50 bucks for a speaker to match his $600 radio was excessive.
I have the set now and am looking for an SP-520 to finish it off. $70

But certainly it isn't necessary to wait around for Elecraft to provide. There
are all kinds of tried and true and well documented ways to do all of the
things.
We've apparently come to the point where we expect our radio vendor to do
