Transatlantic Team Heads to the Coast!

When it comes time to cross the pond, it seems only natural to head to the beach. That's what Marconi did (above we see his team struggling with a kite at Newfoundland). And that is what AA1TJ, W1REX, AA1MY and W1PID are doing today and tomorrow. Here is Michael's message to QRP-L describing the expedition. Good luck guys!

Some of the lads are heading over to the Maine seacoast on Monday
morning for what we're calling a "Rexpedition." W1REX was kind enough
to secure the use of his family's beachfront camp for us for a couple
of days. He explained the urgency to them, saying, "...a bunch of
radio-heads want to talk to Europe with the equivalent of a cellphone
with a dead battery."

Rex, Seab, AA1MY and Jim, W1PID, are going to arrive early on Monday
to begin putting up the antennas. I plan to show up in time for lunch;
hopefully after all the hard work is done. Seab wants to erect a pair
of half-wave phased verticals on 20m. I think the plan is to lift a
160m antenna using one of Seab's big kites.

Our hope is to cross the pond on both 160m QRP and with my
voice-powered 20m transmitter. The weather forecast looks great at
least through Tuesday. My "Code Talker" will be rockbound on
14.055MHz; same as last Thursday. We'll begin the voice-powered 20m CW
attempt the first thing on Tuesday morning (11/10/09). Again, the goal
is to span the Atlantic, but as always, I'll be very pleased to work
anyone that hears me.

By the way, last Thursday's voice-powered operation on 20m was a great
success. Altogether, I worked four stations and received one SWL
report. The best DX was W4FOA in Chickamauga, GA; a distance of
923miles. Tony reported that my 15mW signal was "an honest 579". W4OP
- located one hundred miles to the north of Tony - handed me the same
report and followed up with an amazing recording (you can hear it on
my website). Later in the day I received an email from AD5VC. Dana
reported that he clearly copied my callsign while listening on the LSU
club station (K5LSU) in Baton Rouge; a distance of 1375miles (nearly
half the distance between the Maine coast and London, England).

I thought these were remarkable results for 15mW into an endfed wire
at 35 feet. It makes next week's attempt from a saltwater QTH, coupled
with the low-angle of radiation with a spot of directional gain all
the more exciting.

So please keep us in mind come next Tuesday morning. I'm guessing Seab
will be operating 160m QRP on both Monday and Tuesday evenings.

Thank you,
Mike, AA1TJ

Crossing the Pond... with the power of your voice

Michael Rainey, AA1TJ, has his eye on the North Atlantic. He's been thinking about maritime horns, and how far they could reach. He's built another kind of horn. I'm pretty sure that this one will soon take his voice and -- using ONLY the power of that voice -- send it across the mighty Atlantic. That's a pretty astonishing horn!

Yesterday Michael put a really nice message up on the QRP-L list. This is the kind of message that has earned him the title "Poet Laureate of QRP." Here is an excerpt:

I'm currently sitting at a desk on top of Vermont's highest mountain.
In the far distance I can see the Presidential mountain range of New
Hampshire. Roughly twice as far away is the Atlantic Ocean. The other
night I spoke into a tin can, and the power of my voice carried a
message to the Maine seacoast where K1MPM heard me as clear as a bell.
I think this is absolutely magical. The present prospect of blowing
into a tiny horn and having this pittance of exhaled energy carry a
message back to England - when the bone shaking horn on the old Queen
Mary couldn't carry to the horizon - is nearly beyond comprehension. I
know this is how everyone of us feels when we operate QRP.

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!

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!

"El Silbo": Michael Rainey's Amazing Voice-Powered DSB Transmitter

Oh man, the wizard of the Vermont hobbit hole has really outdone himself this time. Michael Rainey, AA1TJ, has posted a very interesting report on his experiments with voice-powered radio. I was, of course, delighted that he went with DSB. Check it out: http://mjrainey.googlepages.com/elsilbo

I don't mean to seem like I'm taking any credit for this, but I did provide Michael some technical advice on how to increase power output:

Michael: Obviously the Italian elements in the project were of critical importance. Some of them may have escaped your attention. I note that an olive can was involved... For further progress I think you should consider working in some of the other substances that help keep Italy going: cappuccino, Nutela, and perhaps some vino bianco...

Another thing: While you are shouting, be sure to use the proper gesticulations. I recommend that you go Neapolitan here -- they are the best. I'd say that before each CQ, you should put yourself in a Neapolitan frame of mind: imagine that someone has bumped into your car and that you and the other guy are arguing about who is at fault. This should generate at least 20 mW!
