Bill, Pete,In keeping with historical events, I have enclosed a few snap-shots from the 1961 Pittsburgh Press dated Wednesday, April 12, 1961.Yes, a few of us recall that very day. I had filed this newspaper in my Scrap Book back then. It was a bitter sweet thing, to read for most, as we hoped the U.S. to be first but none-the-less, we smiled...
Mark, K6HX, took a break from Hummingbird photography and captured some of the images streaming down from the International Space Station on Cosmonautics Day (April 11): http://brainwagon.org/2015/04/11/sstv-from-the-iss/ Very cool Mark (and I think the bird pictures are just as cool!)

Well, it has happened to me yet again: After a somewhat happy period of stubborn luddite rejection of digital technology, yesterday I decided to jump into the fascinating world of Si5351 PLL chips. I don't have to tell you who is responsible for this decision. But he is of Italian descent and lives in Southern California. I'm working with an Arduino Uno...

Oh the humanity! Pete Juliano has turned his digital attention to previously completed projects. Perfectly fine rigs -- whose only crime was that they used LC or crystal (VXO) oscillators -- are now being ARDUINOED by the maniacal Dr. Juliano. Not even Huff and Puffs will be spared. This is like the French Revolution! We hear that Pete has even mastered the...
Back in 2009 Wes Hayward and Bob Kopski designed a termination insensitive amplifier block for use in BITX-like transceivers. Farhan urged me to use it. The advantage of this design is that the input impedance stays at 50 ohms no matter what you hang off the other end. That's very helpful, especially when you start trying to get specific impedances at the ends of...
I had a nice QSO with Duke, NA1A, out there in Irvine, California on Sunday. Duke has a deep interest in the quality of SSB signals -- he is part of the ESSB group. So I was pleased when he said my BITX 17 sounded good. He recorded a little bit of my transmission. Click below to listen to the...
