Thank you all who responded. I just thought it was time to
check
everything. I think a lot of folks have both amateur radio
and
photography as a hobby. I happen also to like "boatanchor"
radios,
that is, large vacuum tube stuff, probably goes along with
my
interest in large-format cameras. Its gotten very
difficult for me
to manage either.
I have to admit that when I left College I left my system
there in
the attic of the frat house - It was all surplus equipment
and of no
future value. I also left a little 1 watt transmitter
that let me
hook up with a guy in NY from Oklahoma. I further admit
that when I
had to recover all my dad's stuff from Arizona I simply
left his
receiver there.
Once I got out of the navy I had a little 10 meter mobile
activity in
North Hollywood but finally dropped all ham activity since
I got my
radio/electronics fix on the job. No fun simply talking
to some guy
when the main topics of the conversation were how much
power he was
using, what kind of antenna he was using, etc. When I
moved to the
San Diego area to work on the Atlas I designed missile
tracking
systems. The microwave frequencies we worked so hard to
deal with
are now the same as clock frequencies of some home
computers.
Still working on my book but in it I note that most of
what I did at
any time was based on technology or components that didn't
exist even
a year earlier.
My first real-life engineering project was to design a
solid state
telemetry component. I started by buying a book on
transistors,
having never seen one before then. Things do change.

Depending on what you had it might be worth a lot now.
There are a couple of mailing lists dedicated to WW-2 and
later surplus equipment. At the time most of it was sold at
give-away prices and lots of it was seriously modified. It
was so cheap it was used as building blocks for home
projects. Now ARC-5 sets that are relatively intact go for
very high prices. What we didn't understand at the time was
that a lot of military gear was very well designed and
extremely well built. I still have a little in storage and
will dig it out if and when I have more room. This is all
very OT here, its difficult to find a photographic
equivalent to the military stuff. Most military photo
equipment was just commercial stuff with different labels if
even that. I am not including aerial cameras and mapping
equipment here since some of that was pretty special.
