Yes, I know there's never been any real hard and fast significance to
the old USN nomenclature system's numerical increments.  Often, it's
applied to the same equipment manufactered by someone else, or even
the same equipment manufactured by the same people, but on a new order.

But...for years I've operated on the assumption, received from I don't
know where, that there was a small number of 12-vdc systems made as
the RAX, as opposed to the RAX-1.  But my search for several months
was coming up empty.  Now I understand why.

Fantastic!  Even the XRAX was 28 vdc.  All this conclusively demonstrates
there were no 12 vdc RAX-type receiver systems.  Mike, I'd seen your
XRAX pages several years ago but I'd forgotten all about them.

As everyone is aware, I make the most long-winded posts and replies on
these lists.  One of the reason I do that is to try to get a discussion
going, and to encourage anyone to contest *anything* that I've written.
I love it when someone notices something amiss and points it out.  I love
finding out that I was wrong, because I've learned something new about
gear that I enjoy studying.

This little correction really makes my day.  Jay, Robert, Todd, and Mike...
thanks for your replies!
