SolderSmoke: On Sale on Thai Beaches!

An interesting e-mail from Thailand arrived this week. Excerpts:

Hi Bill Now for the full story

Life was so uncomplicated and peaceful before soldersmoke!

Last October I was lying on the beach in Pattaya City Thailand. I was just lying there enjoying a cold rice beer watching the various peddlers trudging along the sand. I wasn't bothering anyone and thought I was enjoying my retired life style. (Little did I know what was about to happen). Casually the wife reminded me there was a Ham club meeting in about three hours, I should hold off on another beer. Ok, I'll manage till later.

Pattaya Thailand has a great little Ham Radio club with locals from all parts of the world enjoying the one universal hobby without boundaries.

We showed up at the meeting on time and found a nice corner table. ( now the plug for the club - the meetings are the Friday after the first Sunday of every month and are held at Jimbos Bar). After about an half a beer a friend from England wandered over and sat next to me. He produced a CD from his pocket and said is was SolderSmoke, would I like to buy a copy for 100Baht. (approx. 3.00US) . As with most normal people, my first question was, what is soldersmoke? This was my first big mistake. I should have said not interested and looked for other friends that were arriving. But, no, I had to ask what was SolderSmoke.

My friend tried to explain, but feel short of being able to fully relay the meaning of the word SolderSmoke. If I remember correctly there were episodes 1 thru 80 something. I took the CD back to my house. and the next day spent over 5 hours glued to the CD player. My world was beginning to crumble.

I listened to more episodes. and started to think in terms of QRSS, QRPp, long wires etc. This new terminology was fascinating. I grew up in Idaho and was first licensed in 1963. I still have my first rigs that consisted of a Hammarlund HQ-100 and a Knight Kit T-60. I apparently had the knack at age 13 or so, but didn't know what it was called then. hi hi

In a couple of SolderSmoke episodes there was mention of a Drake 2B, a great receiver in all respects. I found myself wanting one (I sure didn't need one), and looking every where. I bought one in great condition with the original for sale tag still on it. It even had the crystal calibrator installed.

Now my vocabulary has expanded to whisperers, grabbers, mickums, reggies, knights of the realm and other terms before unknown to my vocabulary. Fessenden was a terrific individual although I'd never heard the name before episode 90 something. I started to build a QRSS beacon. I am in constant contact with Michael Rainey , AA1TJ. He is a great guy and has helped with a lot of questions.

For the first time in several years I am involved with something I enjoy. This is really fun I said to myself after fabricating a one transistor transmitter patterned after the discontinued ONER. 0-Yes let's not forget Mr. Doug Demaw, I bought the QRP notebook and Solid State Design (I didn't tell the XYL how much this book cost).

I've always been taught that addictions are bad things. I am in serious trouble now. I am thoroughly and completely addicted to SolderSmoke. I get impatient and unpredictable when the podcasts are a little late being posted on the internet. It's just like getting your fix for the week. Yes, fix for the week because it doesn't last the full two weeks. hi hi

I guess this is a non e-cursing thank you kind of Email. SolderSmoke has ruined my life, but my new life is much better with it.

Hope this epistle hasn't bored you to much. Your providing a great focal point for fellow knack victims.

Only thing left to say Bill, is KEEP ON SMOKIN!


Thanks for SolderSmoke

More Seismic Action

Two more fairly strong jolts today, both from the same region NE of here. The 4.9 was very noticeable at 11:25 am local time, and the 5.6 really shook the apartment at 19:47 local.
The USGS site is really very useful and up-to-date. Lots of data. For example, we learned that the compression wave from the 5.6 jolt took about 15 seconds to reach Rome. The people up in Abruzzo are really suffering and each one of these aftershocks makes things worse for them.

Earthquake Hits Central Italy

A 6.3 earthquake woke us up last night. Rome was shaking quite a bit. Looks like the epicenter was up in Abruzzo, near L'Aquila. News reports indicate that buildings have collapsed and people have been killed up there.

Deep Solar Minimum

Farhan alerted us to this. From the NASA website:

April 1, 2009:
The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower.
2008 was a bear. There were no sunspots observed on 266 of the year's 366 days (73%). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days: plot. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008.
Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year's 90 days (87%).
It adds up to one inescapable conclusion: "We're experiencing a very deep solar minimum," says solar physicist Dean Pesnell of the Goddard Space Flight Center.
"This is the quietest sun we've seen in almost a century," agrees sunspot expert David Hathaway of the Marshall Space Flight Center.

The Siren Song of WSPR...WSPR DSB?

Man, that's the kind of map that I want to find on the screen when I walk into the shack in the morning. Or maybe on my Blackberry at lunchtime. Above you can see the WSPR spots for Jeff, KO7M. You can see Jerry, NR5A, in there, proudly representing South Dakota. Buried under the Northeast calls is K1JT, the only Nobel Prize winner in the group.
This morning I downloaded K1JT's WSPR program and was very pleased to find that it runs nicely on this old, rickety Windows 2000 machine. (I pushed the envelope a bit and tried to get it to run on my recently revived Toshiba Satellite Pro 400CS, but it didn't seem to like Windows 3.1. ) I have on the workbench the plans for W3PM's bare bones WSPR transceiver and the WSPR care package sent over by Jim AL7RV.
Here is my plan: Make W3PM's rig even simpler. TX only (at first) and Double Sideband. Maybe I'll just put an SBL-1 mixer between the oscillator and the RF amp in my current Visual MEPT transmitter. (I'll make it switchable so that I can go back to our beloved visual mode whenever I want.) Then add W3PM's audio amplifiers between line out on the sound card and the audio input port on the SBL-1.
What do you guys think? WSPR DSB? The other sideband should fall FAR outside the band, and it will almost certainly be completely down in the noise for anyone not running ARGO or SPECTRAN-like software.
