Some SolderSmoke In COMPUTERWORLD

"Hmm... I think I'll give ham radio a try."

Wow! The latest edition of COMPUTERWORLD contains a really inspiring article on ham radio by John Edwards, W6JE. I think this is exactly the kind of thing that could help bring computer enthusiasts into the world of The Knack. SolderSmoke is mentioned near the end of the piece. Thanks John! Nice work!
Here is the link:

The D-104 -- A Completely Respectable Piece of Ham Radio Gear

Recently we have received some comments along the lines of, "Hey Bill, what's that chrome CB-lookin' mic doin' in your shack?" Having come into ham radio during the great Amateur vs. Citizen Band wars of the 1970s, naturally I was quite stung. Fortunately, an old magazine soon arrived with a photo (above) that should end forever any speculation about the D-104 being somehow "CB." The picture above is from the January 1952 issue of "The Shortwave Magazine" from the UK. G3ZI, L.S. Woollatt, is shown with his very fine station. With the exception of his two main receivers, all of this OM's gear was homebrew. Racks and racks of FB HB gear. If a chrome lollipop was OK with G3ZI, well, then I think that settles it.

The GBT: Great Big Thing (Green Bank Telescope)

Oh man, imagine sitting there in the Faraday-caged control room in the National Radio Quiet Zone, in an area in which things are kept so RF quiet that only diesel vehicles are allowed... "Wired" has a very nice on-line article and photo spread on this magnificent antenna:

Listen to "El Silbo" Voice-Powered Rig!

POWER SUPPLY

Michael, AA1TJ, has had more contacts with his voice-powered DSB rig. (Scroll down a bit for a look at the schematic and more comments on this amazing project.) Michael has posted two recordings of his signal (as received at distant stations). When I played these files, Ubuntu showed one of those semi-psychedelic groovy "visualizer" displays, complete with oscilloscope-like patterns; the signal looked FB Michael!
