Monday, September 16, 2013. A BRILLIANT SET BUILDER, A BRILLIANT KIT DESIGNER. Big Nick," KC9KEP, does amazing work. He's been building classic late-1930s/early-'40s ARRL Handbook. Receivers (plus some others) and good-looking as the League originals were, his are even better. If you like building your own ham gear, he's a inspiration. On the other side of the Atlantic and a generation or two more recent in technology, the clever Tim Walford ( Walford Electronics. Links to this post. Coker at left, QU-AX...

Retrotechnologist: TELEGRAPH KEYS AT 2014 DAYTON HAMVENTION
http://retrotechnologist.blogspot.com/2014/05/telegraph-keys-at-2014-dayton-hamvention.html
Saturday, May 17, 2014. TELEGRAPH KEYS AT 2014 DAYTON HAMVENTION. A selection of old keys - and one new one - from the Dayton Hamvention:. Pendograph," with a base-supported vertical pendulum for forming dits. Pendograph close-up. The owner let me try it - very nice feel. It's a "release of tension" design like the Mecograph: the reed is flexed at rest, and released to vibrate when you work the left paddle. This is a Mecograph, one of two versions. Labels: HORACE G. MARTIN AND OTHERS. Im kinda sick that ...

Retrotechnologist: CARBON MICROPHONE CHECKING
http://retrotechnologist.blogspot.com/2015/06/carbom-microphone-checking.html
Monday, June 1, 2015. I went through most of my collection of carbon mics tonight. The old ones are nearly always non-working when found: they pick up humidity, the carbon packs solid, and that's it; or the carbon granules dribble out over time. Not all of them. I found several that still work, and a couple that I'd thought were dead (a Shure Brothers 3-A and a 3-B) aren't. Here are the working ones:. Labels: IN THE WORKSHOP. June 1, 2015 at 6:45 PM. Seems like we did that with the mike in an old telepho...

Retrotechnologist: STANCOR 10P TRANSMITTER: UPDATE 12
http://retrotechnologist.blogspot.com/2015/03/stancor-10p-update-12.html
Thursday, March 26, 2015. STANCOR 10P TRANSMITTER: UPDATE 12. A very long time in coming, I did make progress on the Stancor 10P, getting as far as power supply:. Rectifier heaters and HV, filter caps, filter choke and bleeder. It's a little crowded and I struggled to solder the capacitor and resistor to the chassis, even with the big iron. That work had it almost done, so tonight I added a few more things:. Installed output feedthroughs and connected the output, wired up the primary power and the meter.
