I did my last certification/type acceptance using this "facility" almost 15
years ago, and have pretty well dismantled it. It could be put back
together in a couple of weeks, but until I have the need to do so, it will
remain dormant.

If you wanted to do the grunt work, I could show you how to do it. It is,
so far as I know, still in the FCC database as an approved pattern range.
You have a couple of holes to dig, some plastic pipe and woodwork to do,
and a couple of tables to build.

The thermal chamber was also discarded...along with the temperature
measuring setup. That would need to be rebuilt. Depending on the size of
your device, it can be trivial or a pain. We used a Coleman cooler with a
light bulb as the thermal source, dry ice as the cooling source, and a
computer fan to keep the chamber at a constant temperature. The
"thermometer" was a diode calibrated at the freezing point of water, the
boiling point of water, and extrapolated to the temperatures we needed. The
reality check was with a real thermometer borrowed from the local college's
chemistry lab.

The answer is that if you want to spend a couple of hard weeks at it, you
are welcome to use it. The calibration curves are still accurate and I have
the exact locations of the antenna masts marked...just not dug and sleeved
for the antenna mast. There are better ways of doing it than 4x4 lumber,
and I might like to explore that.

If you got out for "under a thousand dollars" excluding your labor, it
sounds like you have/own/operate your own FCC-certified testing

facility,
is that correct?


That is correct.


As an aside, is this facility/capability available for hire if someone
wanted
to do some pre-certification testing or qualification?
