Was Marconi the First Radio Amateur?
Steve, WG0AT, posed this question in the title line of his latest (excellent) video. I really liked the recordings of Marconi speaking in English. (I'd heard him in Italian, but never in English.)
So, was he one of us? I say yes. Definitely. Why? Because he very clearly had what we would call a shack. This is discussed in SolderSmoke -- The Book. When his mom saw that his tinkering with electricity had some potential (!), she had an attic room in the family home near Bologna configured as a workshop for her Knack-afflicted son. And there he tinkered. Just as we do.

Dino's Awesome Workbench
People send me these images, and they are so good that I feel compelled to put them on the blog. From Dino:-------
Ok, can't stand it anymore....had to show off my workbench as well. BTW, will be making a presentation at Dayton Hamvention in May on "Building Your Ham Radio Workbench." So if guys have any great ideas to pass along would love to hear them and include as possible. Am gearing this toward the beginner and focusing on basics, soldering equipment, tools, safety, the bench, parts accumulation, etc. Over the past two years have made pitches at Hamvention on Test Equipment and Station Engineering Manuals....always lots of fun.

AA0MS's FB Workbench
Doug, AA0MS, sent us this nice picture of his workbench and operating position. (That looks like a nice oscilloscope!) Doug is blogging at http://aa0ms.blogspot.com/ Lots of good stuff there about his electronic adventures. I liked the pictures of the old homebrew gear that his dad built. Thanks Doug!

The FUNKY Keyer
Paul up in Manchester has some really intriguing ideas on CW and keyers. He likes highly personalized CW from straight keys, and thinks he can even hear the influence of Latin-based languages when receiving signals from stations in France and other Romance language countries. (Like me, he also thinks a bit of homebrew chirp adds some character to signals. ) Automatic keyers seem to squeeze all of the individuality out of CW. So Paul has written some computer code to put that individuality back in! Can we get a "Lake Erie Swing" option Paul? Check out Paul's blog. Interesting stuff! Hi Bill
Further to the kind words of introduction you gave me as a “new homebrewer” in Soldersmoke 104, I’m writing to let you know about a little project of mine which I think you might appreciate…
I made a h/b keyer a while back and recently added the ability to send automated 3*3 cq calls (and cq FISTS calls).
On doing this, I realized how much I HATE the sound of machine generated CW – so mechanical and lifeless. I want to hear a real fist – preferably with some chirp and drift thrown in for good measure!
So – I’ve come up with an alternative – The FUNKY keyer!
It adds some random timing "jitter" to each automated cq call, to simulate the sound of a real fist on a straight key.
You can read all about the Funky Keyer on my blog, http://m0xpd.blogspot.com
The blog also documents some of the other outcomes of my personal puffs of solder smoke, including the “Funster PLUS” 40m CW Transceiver and the “Not-so-superhet” experimental valve receiver. There’s some operating stuff, including WSPR on 40 and 80m with my Softrock SDR and I was inspired by Soldersmoke to include some travelog – ZL, VR2, BY, HB, etc.
Hope you enjoy it.
Let me take this opportunity to thank you for all the enthusiasm and inspiration you continue to give us in Soldersmoke,

Vernal Equinox!

Today marks the Vernal Equinox, an important day for QRP radio amateurs. In the Northern Hemisphere, conditions usually start to improve. And this year's equinox is accompanied by higher sunspot numbers. So cheer up guys! Better conditions are on the way.
The equinox comes at 1732 UTC today, 20 March 2010.
Spring seems to be getting off to a good radio start here in Rome. My 20 mW WSPR signal made it across the pond this morning, 8289 kilometers to W3HH (see below). This was the first signal report of the day. I only seem to cross the pond around my local dawn -- never around sunset.
