Default Free: Seattle area; QST and old microwave and pulse gens

Hi all. I'm doing some serious cleaning. Maybe someone in the
Seattle/Everett area would like to pick up any/all of the following:

QST. Feb. 1971 through July 1996, missing Feb, Mar, Apr, Sept 1973
and May 1991.

TS-592/UPM-15 pulse generator. Vacuum tube here. About 45Hz to 10kHz
PRF, makes double pulsed with adjustable widths, delay, ... This may
be valuable more for the power transformer and the 829 output tube.
Last I had it on, it actually did work.

Systron-Donner model 108 solid state pusle generator. Has orig.
printed manual. Needs some work in the output stage--should be enough
info, incl. schematics, in the manual for a good tech to do this. I
could, just don't have time I want to spend on it. Rep rate 10pps to
10Mpps internal, or ext trig to 0pps. Can generate a single pulse, or
gated from ext input. 50 ohm output: 0.2V to 50V into 50 ohms.
That's 50 watts during the pulse.

TS-403B/U RF generator. Klystron-based generator, 1.8GHz to 4.0GHz.
This is the same as an HP something or other...I have a photocopy of
the HP manual that will go with it, but couldn't lay my hands on it
just now. It oscillates, but I'm sure it needs adjustment per the
manual of the repeller voltage tracking vs frequency.

Cross my palm with enough greenbacks and I might ship one of these,
but it would not be cheap.

Cheers,
Tom
