[MRCG] Some items I'm brining for the swap

Wed May 4 17:34:55 EDT 2016

While I'm taking a break from packing, let me advertise some stuff I'm bringing for the swap meet.

First, is a dynamotor, sealed in its wooden crate with a 1948 packing date. I believe that Dennis told me it's the dynamotor only from one of the WW2 radio power supply units, but I don't remember which one, and I've been too busy packing to study the labels in detail by flashlight. :)

Next, a panel-mount 400 Hz variac. The big knob has a big chip in the skirt, from the knob falling off and landing on concrete when I turned the variac over. DOH! The two broken-off pieces are included for gluing back on.

I'm bringing the little 28 VDC to 115 VAC 400 Hz 3 phase rotary inverter I bought last year. I think it's really cute, and I would love to find something suitable to power with it! But I've had no luck doing so in the last year, so I'll also consider letting it go home with somebody else.

I'll have a little morse code practice oscillator with U-79/U jacks (the Korean era US 10-pin audio plugs) for the keys. Looks like it was fabricated locally at some base?

I'll have the neat mystery code box (transponder? test equipment?) that I bought from Bjorn last year. I haven't gotten around to reverse engineering it yet. I think it's more likely to be transponder related than crypto related. It appears to be a prototype or one-off, very professionally made by a military contractor.

All of the above stuff interests me, but I haven't gotten around to doing much with it yet, so I don't mind whether it goes home with me or somebody else.

Now, for an item I picked up recently which I do not want to bring back home: It's a cool looking transceiver marked "DEPARTMENT OF THE INTERIOR GRAZING SERVICE". Based on Wikipedia, I think that makes it date to somewhere between 1939 (when the Division of Grazing, created in 1934, was renamed U.S. Grazing Service), and 1946 (when the Grazing Service and General Land Office were merged to form the BLM. Do we allow attachments on the list? Let's find out:

As per our rules, none of these items will be available prior to 8AM on Saturday. I do have a few pre-arranged (as in, arranged months ago) radio handoffs, and one vintage computer (and IBM System/23) that is hitching a ride up to the Bay Area with William, so don't be upset if you see me transferring those earlier. ;)

There were some other items which I also considered bringing for the swap, but my back said "ENOUGH!". :)

Now, I know it's a long shot, but I sure hope that Santa heard my radio transmissions and brings me a Hellschreiber this weekend. :)
