It's an INVESTMENT!

 

Exactly what we've been saying about Drake 2-Bs and copies of SSDRA!  

Argentine SSB (BLU) Homebrew from Guillermo LW3DYL

Really nice work.  BLU is Spanish for SSB.  (Juliano BLU?)

But I think Guillermo needs to build ONE MORE BOARD!  A VFO or a VXO.  Analog. To finish the job.    Guillermo tells me this is in the works -- he selected an IF of 11.0592 MHz specifically so that he can use a variable oscillator built around a 4 MHz ceramic resonator.  

Complete schematic and PC board patterns on his site:

Homebrew Lives! TWENTY N6QW Simple SSB Transceivers Under Construction in Northern Virginia

IF strip by Don KM4UDX

This has to be one of the most successful of SSB group-build projects.  Dean KK4DAS has been leading 20 members of the Vienna Wireless Society in the construction of N6QW's Simple SSB Transceiver, with Dean's "Furlough 40" additions.  This is very FB, and very encouraging.  Dean clearly has The Knack.  Just two winters ago I was smuggling a 3.579 MHz crystal to Dean for use in a Michigan Mighty Mite.  He has clearly made a lot of progress.

Dean writes: 

It has been just over a year since I completed my initial build of the Furlough 40 with much coaching and assistance from Pete. Mike and Don are two out of 20  members of the Vienna Wireless Society Makers group that is working on a group build the SimpleSSB project as enhanced by me to include features like CAT control for digital modes.  Beginning about six weeks ago the group is progressing module by module per SolderSmoke best practice advice.  We started with the audio amplifier, followed that with the Arduino/SI-5351 based controller module and the builders are just completing the IF module.  This week at our weekly meeting, Mike proudly showed off his success.

For Your Vacuum Tubes: Isotopic Ionization Sources from U.S. Radium

One or two podcasts ago I mentioned radium in regulator tubes.  As I predicted, this provoked a number of comments about how silly it is to even mention such things. Nonetheless, I find it interesting.  It seems that real radios really do glow in the dark!

RIP Isamu Akasaki -- Shared Nobel Prize for LED -- Analog Guy

From the obituary in the Washington Post: 

In addition to the Nobel Prize, Dr. Akasaki’s honors included a 2009 Kyoto Prize — Japan’s highest honor — recognizing developments in advanced technology. He found that some technology, however, needed no advancing at all. He took great pleasure, for example, in long-playing classical music records.

On that point, he joked, “I am analog.”

"The Perfect Trap for the Engineering Mind" -- Leo Fernekes' Stirling Engine

I did a post about Leo back in August:

Although it is not about radio, homebrewers will find much to resonate with in Leo's Stirling engine project.

Shortwave Event: Brother Stair is Dead

A Satellite Ground Station (Receiver) Made from Junk

Very cool.  This guy (who brew up on an island in Alaska) really knows how to use aluminum tape and the junk that fills most workshops. I like his use of the security camera mount as an az-el antenna rotator. 

I foolishly discarded a Direct TV dish.  I could have been receiving GOES images by now! 

Just last week I got the same RTL-SDR.com V3 dongle that he is using.  Very FB.   It does HF direct sampling with no hardware mods and no upconverter.
