Happy New Year! SolderCake!

This is just so good, I felt the urge to share it immediately with the SolderSmoke community. Thanks Tom, and Happy New Year to all!

Bill:

Happy New Year!
I am yet another listener who discovered your podcast by accident and am now hooked. I also thoroughly enjoyed your book. Both take me back to the days of scrounged parts and burned fingers, building balanced modulators and an FM stereo transmitter that earned me an invitation to leave a great southern university.

To celebrate the new year, rising sunspot numbers, and your 120th podcast, I offer the attached photo of a Solder Cake. It features 120 rolls of 60/40 rosin core solder -- several brands and gauges. The cake actually weighs 123 lbs. because the roll holding the soldering iron at the top is 4 lbs. It has zero calories, but definitely contains lead! It should be baked at less than 370 degrees, or the icing tends to run.

Why would anyone have 120 rolls of solder? I don't remember precisely, but rumor has it that ebay and alcohol were involved.

73, and a wonderful new year to you and your family.

Chinese HAMSAT HO-68

PA3GUO put together this nice video. Check out the large footprint of this relatively high-orbit satellite.

On the air, out in the woods... Plus, olive news

We were out in the Sabine hills this week. Things are starting to settle down out there: The Cinghale are, well, mostly GONE (see earlier post), and the gunfire is starting to die down. And the olives have all been shaken from the trees. All was going well, but my wife was worried that with temperatures dropping, she might find me frozen out at my front porch operating position, so she secured indoor accomodations for me and the HW-8. Wow, what luxury! My CW is back to normal -- the shivering had been a real impediment. On Monday and Tuesday I was on 80, 40, and 20 with the Heathkit. I managed to work seven stations using a far-from-optimal end fed wire with my flea market tuner. It was fun to work Russian stations -- UA6HNU was running a homebrew rig. It reminded me of the good-old days in which most of the Russian hams were running HB gear. Then, just as we were getting ready to head back to Rome, there was some icing on the cake: Near the top of the 20 meter CW band I heard KZ1H (see earlier post) all the way from Boston.

Next week, a better antenna goes up.

I got some questions about the olive harvest. It seems that the trees around are place are about 200 years old -- mere kids, considering that there are olive trees in the world that are 2000+ years old.

As for the harvesting process, the shaking machine vibrates the tree for about 5 seconds. The workers have a collection tarp on the ground to catch the olives. Then they have machine that reels in the tarp.

Stagnosald! (Italian flux)

For some reason I like the packaging for this Italian soldering flux. Sort of takes you back to the days when soldering was soldering, if you know what I mean. Now (somewhat ironically) we are using this flux for SMT soldering. On the left you can see the PA stage of my slowly-coming-together SMT SDR LINUX Compu-radio. As you can probably tell, I am struggling to keep a positive attitude towards SMT and SDR. Lately, even Linux has been giving me trouble. The problem here is clearly with the operator, not the equipment. The Softrock SDR kit is really excellent. I'm sure I will eventually get it working, but I think there will be a lot of geezer-like complaining about all this new-fangled surface mount, software stuff. Please, bear with me.

Glowbug Christmas

My "Mate for the Mighty Midget" receiver (with 6U8s)

Some excellent Christmas verse from Brad, AA1IP:

The Glowbugs' Christmas
******************************

T'was the night before Christmas
And all through the shack
Not a heater was glowing
In all of the rack.

Sitting totally silent and quiet that night
The old HRO shed nary a light.
The Johnson exciter and its homebrew final
Felt cold as leftovers, or seat-cover vinyl,

I drowsed at my workbench feeling tired and weary,
The print in the Handbook looked fuzzy and smeary.
I thought, "I'll make coffee", and groaned to my feet
When I heard a loud clatter outside in the street.

What the--? I wondered and turned on the lights
And there I beheld a wondrous sight:
A battered old van heaped high with components
And a grizzled old ham with a bagful of doughnuts.

I noted his callsign-- can't recall it today--
But a patch on the side read "FMLA".
I opened the door and hollered "Come in!
The coffee pot's heating, and we'll sit down and chin!"

He spoke not a word but whistled in Morse
A "GE OM", and "By golly, I'm hoarse.
Too many contacts, and hot rosin smoke."
I nodded and poured him a mug of jamoke.

He emptied the doughnuts in a pile on a plate
And explained in a whistle, "I'm running real late.
I've new 6L6s and fine 211s, 6146s and good 'SN7s.
And 866s and 0B2s, type 45s and mil-spec 807s."

"For the regennie crowd, 201s by the score
And good ol' type 30s and 19s galore.
I haven't neglected the passive-parts run
There's lots of good iron by old Thordarson."

I nodded and smiled, suppressing a chortle
As he reached in his pack and left me a 304TL.
He whistled, "I'm leaving, the coffee was great,
But I'm overdue in the neighboring state."

"Keep everyone building the rigs of their choosing
Or we'll lose the bands that we're lazy in using.
Transistors or tubes-- any project is fine--
Just keep on constructing and sharing on line."

He leaped to his feet and waved a gloved hand
As he sprang for the door and his rusty old van.
I heard him exclaim as he drove away from me,
"Merry Christmas, you Glowbugs, and to all 73!"

****************************

(With apologies to Clement Clarke Moore, who surely would have
been a ham had radio existed in his time. Alas, all he had
to build with was words.)

For new readers: the FMLA (Five Meter Liberation Army) appeared in a
series of short stories written by Michael N. Hopkins, AB5L (sk). If you have never
read these, you're in for a fun evening!

For QRP fans: the numerical references in the poem are for classic
vacuum tubes, several of which operate at QRP levels (whether or not that was the
original builder's intention) and (mostly) within the amateur bands.

Christmas Greetings from Lunar Orbit

I always liked the last, very inclusive line in Colonel Borman's 1968 Christmas Eve message.

"Wired" magazine also made note of the important Christmas Eve radio message (1906) from Reginald Fessenden: the very first "phone" transmission. Fessenden himself played the violin ("Oh Holy Night").

Merry Christmas from Rome! 73 Bill

A Report from South Africa

Hi Bill

Africa "field QRP station"
Thanks for another great episode of your experiences - I'm tuning in from Africa while on my vacation Each December I make the trek from San Diego to Cape Town.
Then, my Dad (zs1xd) and I take the family out to a remote
location - and setup a field station. Around the camp-fire, under the Milky Way and no rf-pollution is a great way to hunt some dx and spend vacation time. This year
we selected a cabin located in a beautiful mountainous region about 100 miles north of Cape Town. 2 wheel vehicle will get you there and "just in case" , we
also took a capable 4x4 with.
I posted some pics and QRP HF operating notes here: http://k6wh.blogspot.com/

"SMT"
I'm following your Softrock SMT construction comments with keen interest and am glad you're finding the challenge - well - "not so much of a challenge"
I think it's so great that you're encouraging hams to jump into SMT.
I chuckled at your comment about "desoldering smt's" - Try de-soldering the Si570 SMT chip. I had the good fortune of measuring messing up the
"measure 10 x then cut once" when soldering this IC on the rxtx kit. Well - we know a mistake will happen, and when it happens, murphy's law will ensure
that it involves the most sensitive and tricky smt component on the board - hi.

It's a real trick, due to the contacts being under the chip (no pins like the other smts)
Well - try de-soldering that piece. And of course one realizes the mistake, only once the last solder joint has dried. Determined to correct the mistake there and then,
at 9pm while busy with the kit, I rushed off to the nearest radio shack to get some de-solder wick. Took me about 1 hr of patience, and careful "wicking" to suck
up all the solder underneath the chip - one contact at a time, (each desolder attempt, hoping the chip pops loose) - no easy task. I don't know of another easy way
than lots of patience, and a good magnifying glass.

I agree there is no greater reward than "homebrew" and with the advances in SDR tech, we're surely living in a wonderful age.

Once you get the SDR on-air, I'm sure you'll be blown away by the reception quality - sensitivity and especially the almost non-existent noise-floor.
(I'm not sure which model you're building, but I think all of Tony's designs are utilize the same Tayloe detector design which is very quiet)

I still can't believe the performance I get with the Softrock's kit - It's now become an antenna measuring instrument - While having fun with PSK QSO's and WSPR.
Of course, with the SDR one can adjust the output (via soundcard drive) to basically uW levels.

As we know, at these levels, each little bit of antenna optimization helps, and SDR+WSPR/PSK has become my "far field antenna measurement tool" of choice.

WSPR from Africa
Not too many stations active on WSPR on the African continent - Now that I've setup my Dad on DSL, I assisted him in activating his WSPR station in
Cape Town (ZS1XD). His antenna is a 20m homebrew 2 el yagi. I'm pointing it north during the evenings to see if n2cqr pops up in the log. Nothing yet, but I'm sure
one of these days, you may just be surprised. Keep watching for the Africa report :)

thank you again for such a great entertaining and educational program ...
73 - best wishes to you and the family from the tip of Africa.

Technical woes: Linux, WSPR, SSSSS

Help me, help me! I want to get WSPR running on Billy's Asus eeePC. I have Ubuntu Easy Peasy running off a thumb drive. And I have the WSPR sofware package in in the machine. But I can't get WSPR to run. I click on it, and the machine asks me if I want to run the program. Indeed I do! But nothing. Help me Linux heads! What am I doing wrong? I've tried running it from the terminal using the instructions in K1JT's excellent manual (see, I have read the manual!) but the computer informs me that I need superuser privileges. Now what?

Also looking for feedback on the SSSSSSS problem. Was it better in SolderSmoke 119?

Thanks!

Crossing the Pond to KZ1H

We were out the Sabine Hills this weekend and on Sunday afternoon I go on 20 CW with my trusty HW8. I made just one contact, but it was a GOOD one. KZ1H pulled me out of the noise and we had a very nice chat. My fist was not at its best, because it was COLD in those hills -- I'm arranging now to move the shack off the front porch and into the heated (I hope!) library.
Anyway, from the courteous way in which he persisted in copying my QRP signal, I knew that OM George, KZ1H, was a FB ham. Sure enough, when I plugged his call into Google this morning, I was taken to a site with the above picture of George in his younger days. Note the bug and the mill, and the homebrew transmitter. Here is George's story:

I grew up in Corona, Queens, NYC. I became interested in radio at the age of ten or so. My father bought an "Eilen" and I was introduced to Morse code. I met many hams around town (W2HDK, W2KAP, W2APT, W2KCD, W2JGV?). They were all very cordial and happy to show off their rigs.

In April of 1939 (age 14), I took my test at the FCC office at 641 Washington St, Downtown NYC and became W2MDE. My father bought me a Hammarlund Comet Pro (plug-in coils with shield cans). I built an oscillator/ transmitter using a type 59 tube.

I was invited to join the W2USA radio club at the 1939 NY World's Fair. W2KU was the Chief Op and my boss. We handled a lot of traffic for the fair visitors and kept the station on the air during the winter when the fair closed between summer sessions.

At 16, I graduated from high school and went to work for a large patent law office as a clerk. From there I went to work for Hazeltine in Little Neck, NY. I thought I might faint when I saw that my first check at Hazeltine was signed by Jack Binns, the radio operator who was the subject of the book "SOS to the Rescue".

At 17, I was made chief inspector of Hazeltine's first war-time production line and worked along side of Frank Hinners.

When I turned 18, Mr. Bailey of the ARRL became head of the Bureau of Scientific Research and Development in Washington, DC. He invited me to become a member of the Army Intelligence Service when I was drafted, which I accepted.

After the war, I attended the Cooper Union School of Art in NYC. I worked for PAA, Grace Lines, Andrea, Sperry Gyroscope, Varian Corp, and Global Systems. Much of my career has been in microwaves. I have been retired for 20 years and am still active on the bands. My present call is KZ1H.

I have been married to my wife Mildred for 53 years. We have three daughters, Jean, Janet and Diane.

Dale Parfitt, W4OP, Homebrew Hero

Yesterday, in my search for pictures of the Drake 2B, I came across VE3MPG's excellent interview with Dale Parfitt, W4OP. Dale and I crossed paths years ago: After I built my first version of Doug DeMaw's Barebones Superhet, I went out on the net and found a couple of kit versions of this receiver for sale. A few years later, I was working on one of them, and turned (as you do) to QRP-L for some advice. Dale came to the rescue and we started exchanging e-mails. After a while he told me that the version I was working on sounded familiar. Sure enough, he was the original builder! The story appears in SolderSmoke -- The Book.

Here is further evidence that Dale and I have similar tastes in receivers: Pictured above is his solid state version of the Drake 2-B. FB! I note that the dial scales are the same as the hollow-state version.

Here is the VE3MPG interview:
