I had to go solo this year, while Tam stayed home to meet the AT&T tech. This meant, of course, that I lacked even the modicum of restraint she sometimes adds--
Meissner Analyst, which is a kind of "test bench in a box" for receiver servicing, and a 1950s Harvey-Wells Bandmaster, a 25 to 30 Watt AM/CW amateur radio transmitter. Both appear to be pretty clean; the transmitter needs an external power supply, 400 V at 200 mA.
Other neat stuff: a pair of vintage binoculars in good shape -- didn't have anything but toy versions, so for $35, why not? -- a very good push drill with (hard-to-find) straight bits and a "Handyman" Yankee screwdriver' a full set of Birnbach ceramic antenna insulators, chassis-mount octal plugs (good for power supply connections), three General Radio mixer knobs, a couple of Dakaware knobs, a National tube socket and 100 pF variable cap, another 100 pF dual variable capacitor, an SW-3 coil form, a 6F7 tube (possibly for a project) and a pair of 6L7s (used in my microphone mixer). Plus four 1940s/50s QST magazines, three quartz crystals and and assortment of other nice small parts. Not shown, a short (10'?) desktop rack and a large toroid core to wind a balun on (you want 'em big -- magnetic saturation is lossy and can produce a lot of heat!).
I met my dear old friend Don H., and several other people I know slightly, including the talented Jim Borgioli,whose ham work includes building very nice AM transmitters that run at or near the legal power limit. And one ham who knew me! A young man who'd gone looking for info on the Stancor 10-P transmitter and found my postings about it on Retrotechnologist walked up to in the flea market area, asked, "Are you Roberta?" and introduced himself.
Found but missed a nice balanced antenna tuner. I should have purchased it at first sight! But it's a cloneable design and I think I have the parts.
A fun time! When I returned home, the phone tech was there -- and pointed out a very large broken limb on the roof and my ham antenna and still loosely attached to the tree. I climbed up and had a look, but it's too big and too precarious for me. We've called the singing tree hippie, who does great work at a fair price.
