Sputnik Madness! But was it CW? or AM?

Our worldwide team of Sputnik enthusiasts continues to seek out the elusive schematic diagram of the spacecraft's 20 MHz transmitter. American, Cuban, Russian and German radio amateurs are involved. Recently Bruce, KK0S, visited the Kansas Cosmosphere in an effort to get a look at the innards of Sputnik's "flight spare." The picture above is his -- it shows the Sputnik antenna connection. (More pictures from Kansas here: http://s747.photobucket.com/albums/xx120/trader_vic/Kansas%20Cosmosphere/)
There was bad news and good news from the visit: The bad news was that the spacecraft on display was a hollow sphere. The good news is that the internal parts --including the transmitter -- might be in storage someplace, just waiting for our reverse engineering. Stay tuned (to 20 MHz!).

Speaking of which, I have a question: OK so the crafty Soviets picked 20.oo5 MHz for some good reasons: Being so close to the WWV freq, it would be easy for hams and SWLs to find it with precision. In the November/December 2007 issue of "Break In" (from NZ -- thanks Jonathan-san!) ZL3DW notes that this frequency selection would allow a receiver set to exactly 20 MHz to "produce an audio tone plus or minus the Doppler shift without ever going through zero beat." But zero beat with what? Most of the receivers out there would not have had BFOs, right? So the Soviets wouldn't have been using ordinary CW, right? Were they using AM, with the beeps produced by an audio oscillator modulating the carrier?

Here is a update from our Chief Designer, Comrade Mike, AA1TJ:

I currently have a prototype for a simple "Sputniker" transmitter on the bench using a 1sh29b in the oscillator and a 1p24b working as the PA. As in the original, the input DC PA power is 1watt. The crystal-controlled oscillator uses an inexpensive ESS 21.060kHz xtal. So far, all systems are GO.

BTW, here's an example of how inexpensively these lovely little tubes may be purchased. Oleg, RV3GM, and his pals might be able to do even better.

Although there are only so many ways one can build a two-tube, crystal-controlled MOPA transmitter, we'd still very much like to nail down the original transmitter circuitry. Bruce, KK0S and Peter, DL2FI are following up leads to that end.

Once we're a bit further along I'm hoping that someone will step-up to produce a kit. Actually, last evening someone raised their hand to ask if a kit were already available.

Dasvidania,
Mike, AA1TJ

Please Put Drake 2-B Serial Numbers Here!

Let the count begin! Folks have been sending in Drake 2-B serial numbers. They've been coming in via the blog, via e-mail, twitter tweets, Facebook messages, carrier pigeons, etc. I'm afraid I might miss some precious numbers. So let's put them here. If you have some, and I don't have them below, you can post them as a comment to this blog post. When we get enough, we'll turn them over to Scott, K6AUS, for analysis using the same mathematics used to determine the number of German tanks during WWII.

Armand's 2-B (X3)

Good morning Bill!,

Let me start of by letting you off the hook (a little anyway), by saying that I no longer hold you responsible for the escalating values of the Drake 2B. After acquiring one, cleaning it , recapping and tweaking it, it's pretty clear that the 2B doesn't need anyone to sing its praises. It sings pretty well all on its own! Having said that, I really have to thank you for nudging me into finally getting one for myself. After a lot of searching I finally found one that was in not too bad shape for its age. I also found two others that were in less than working condition. For a while I was troubled as you were about having more than one Solid State Design. Is it really ethical for someone to have more than one 2B? Fortunately I can rationalize with the best of them. It's obvious that I will only own them for a while and am saving them from the scrap heap. Maybe we could start a 2B rescue organization?

Also thanks for the WARC and 160M tuning template - much appreciated!
The serial numbers for these sets are

2599, 5149, and 12038

Will be neat to get an estimate for the final count. Good luck!

Also wanted to mention that I really enjoyed SolderSmoke "the book". Will there be a second volume? Enough for now.

Keep the solder flowing and the podcasts and blogs comming.

Thanks again,

73's

Armand WA1UQO

p.s. If you have an extra set of crystals for a 2B that you would be willing to part with, let me know.

More on Merrill Budlong, W1MB

K1KT's recent e-mail alerted me to the interesting life story of Merrill Peckham Budlong, W1MB. Wow! What a guy! Killed a Great White Shark with a spear gun! Homebrewed his own diving gear! Insisted that the hams he was Elmering actually UNDERSTAND the circuitry! And -- most importantly -- he was obviously a very good person.

We don't run many obits here on SolderSmoke, but even though he passed away four years ago, we thought it would be a good idea to reprint W1MB's. His story can be an inspiration for us all.

Bob, W1YRC, wrote this about him: He was responsible for launching a great many Amateur Radio careers in Rhode Island. He was uncompromising in his teaching and demanded that all his students understood why a circuit performed its function or why it was essential to know how to solder correctly. He was respected and loved by hundreds of hams that knew him.

Here is a para from his obituary:
An active, athletic man, as a teenager Mr. Budlong made his own surfboards and sailing kayaks. In high school and college he was on the wrestling teams, played trumpet in dance bands, and was a lifeguard at Bonnet Shores. He graduated from Cranston High School in 1931 and from the University of Rhode Island in 1935 with a bachelor's degree in business. He was a member of Phi Mu Delta fraternity and Phi Kappa Phi honor society. During World War II, he held a second job at Kaiser Shipyard in Providence. As an avid amateur radio operator (call letters W1MB) and proficient Morse Code operator, he enjoyed contacting radio hams throughout the world. He founded the Fidelity Amateur Radio Club, which met for more than thirty years at his home. He was a Major in the R.I. Civil Air Patrol and a director of the New England Wireless and Steam Museum. Mr. Budlong was an alumnus of Fidelity Chapter DeMolay in which he was a Chevalier. He was a member of the Narragansett Bay Wheelmen and, into his 70s, participated in bicycle races and 100-mile rides. He was often seen riding his bicycle around Edgewood and Pawtuxet Village. He was a pioneer skin diving and spear fishing enthusiast. In the 1940s he built much of his own equipment before it was commercially available. In 1964 he speared a ten foot great white shark in Narragansett Bay. He was also a frostbite sailor, member of the Edgewood Yacht Club, and member of the Coast Guard Auxiliary.

Merrill Budlong's Drake 2-B

Hi -

I just listened to Soldersmoke 134 and was delighted to hear the reading from Peter Doherty, W1UO.

I first met Peter just before his transcendent 2-B experience. He joined the Fidelity Amateur Radio Club, then K1NQG, of Cranston, RI, which was started by Merrill Budlong (SK), then W1QLD, later W1MB, in 1958. Merrill had a 2-B at that time, so I am almost certain Peter was referring to Merrill's receiver.

Peter received a bachelor's degree in English from the University of Rhode Island. He was an adventurer. After college, we briefly worked together at Merriam Instruments, which was owned by Robert Merriam,W1NTE. (Bob is the founder and curator of The New England Museum of Wireless and Steam in East Greenwich, RI.) Peter soon got wanderlust. He loaded his backpack and took a 1 year trot around the globe. I was astouded when I got a Nepalese postcard from him! Since then he helped deliver vessels from the east coast to Seattle via the Panama canal, worked at the Voice of America, worked in marine electronics in Port Townsend, Washington, and has worked for at least two communications equipment manufacturers. I'm sure he had many other adventures.

The Fidelity Amateur Radio Club is still alive and doing well. Some of the original members are still active with the club, but most of us are gray/bald, fatter, and move slower, but we still love the hobby and appreciate what Merrill did to get so many of us started in our careers. Since Merrill's passing his callsign was transferred to the club and we used it this past Field Day.

Keep up the good work! We ARE listening!

73,

Beautiful Shot of Three of Saturn's Moons

(Photo from NASA, text from New Scientist)

A study in contrasts, this photo captures three illuminated moons as a darkened Saturn looms in the shadows. Only the planet's rings are visible but its shape can be traced from the way it partially obscures its rings and one of its moons.

The large foreground moon is Rhea at 1528 kilometres across. Nearly a third of Rhea's size, sunny Enceladus is on the right. Dione, at 1123 kilometres wide, rounds out the trio to the left with a night-cloaked Saturn obstructing part of it.

The photo was taken by NASA's Cassini spacecraft in April. Cassini has been exploring Saturn's 62 known moons since it reached the ringed planet in 2004.

Copthorne's Heathkit HW-8

Here's evidence that I am moving ever further along the ham radio hippie trail: This week as I was browsing through the 1970's era columns of Copthorne MacDonald, I came across this gem about our beloved Heathkit HW-8. (The photo is of Cop's rig.)

http://infoark.org/InfoArk/Sustainability/Mother%20Earth%20News/70/MEN_CD/mendemo/dcd/047/047-040-01.htm

Inspired, I connected mine to my salvaged and solar-charged gel-cell battery and made a number of contacts on 40 meters. It was all really groovy.

Peace, Bill

WOW! The Reverse Beacon Network

In the European dispatches of Mike AA1TJ I saw mention of this new thing called the Reverse Beacon Network. Then SPRAT shows up in my mailbox (HOORAY!) and I see mention of the RBN there. So this morning I figured I'd give it a little test: I called CQ on 40 meters using my Heathkit HW-8. WOW -- it didn't take RBN long to get me! See above. That's after only about 3 minutes of CQing.

This is a really amazing and innovative development. The network makes use of "skimmers" that use Software Defined Radios connected to the net to search for CQs. When they hear one, they automatically post the info on the web. It is sort of like WSPR, but it is aimed at ordinary CQ calls. Fantastic. Check it out. You will like it!

Copthorne MacDonald and New Directions Radio

I mentioned in SolderSmoke 135 that somehow I feel myself becoming a bit of a hippie. I'm riding a bike to work. I now have a compost pile and a vegetable garden. I'm enthusiastically helping Billy fix his electric guitar... Mike, KC7IT, wrote in to let me know of an important ham-hippie connection that I'd been completely unaware of.

Starting around 1973, a fellow name Copthorne MacDonald (what a great name!) wrote a ham radio column for Mother Earth News. (Further evidence of my drift: I've recently been buying this magazine!) It is an interesting mix of radio technology (much of it homebrew and QRP) and what at the time was called "alternative lifestyles" (communes and all that). Lots of info about sustainable and eco-friendly living, solar power, etc. Here's a good example:
http://www.motherearthnews.com/Nature-Community/1975-07-01/A-Low-Cost-Start-Ham-Radio.aspx

Copthorne MacDonald is the inventor of Slow Scan Television.

I really like Copthorne's writing and I was really pleased to find out that much of it has survived and is available on the internet. Mike KC7IT points us to more of the articles:
http://www.motherearthnews.com/search.aspx?search=new%20directions%20radio&sorting=oldest

Cop's writing constitutes another treasure trove of ham radio literature for all of us!

I found an archive (infoark) that seems to have his "New Directions Radio" newsletters:

I was please to find that OM Copthorne is alive and well. He posted this on eham.net back in November:

Hello all. This is from Cop Macdonald, now VY2CM, his very self.

Many thanks to Benn Kobb AK4AV for alerting me to this page, and thanks for the supportive comments above from a number of you.

A brief summary. I'm not currently on the air, but as Benn noted I was at the 2009 Dayton Hamvention where I gave the talk he mentioned and received that year's Technical Excellence Award for the SSTV development work I did some 50+ years ago as an engineering student at the University of Kentucky. While doing some Googling for Hamvention info I discovered that in 2007 I had been inducted into CQ Magazine's Ham Radio Hall of Fame. Perhaps CQ, too, had trouble tracking me down, as this was news to me. If anyone is interested in the details of that initial SSTV system, the Kentucky Engineer article on the subject is online at http://www.copmacdonald.com/KYEngineeerSSTVArticle.pdf. The QST articles on that first gear appeared in the August and September 1958 issues, and are available online from the ARRL digital archives.

The Mother Earth News column ended in 1983 when the magazine changed hands for the second time. I continued to do much writing after that. A lot of it dealt with energy conservation and energy alternatives --- some examples at http://www.wisdompage.com/SEUhtmDOCS/conservation.htm. In the late 1980s I developed an interest in wisdom, and have written three books on aspects of that subject. Connected with this, in 1995 I started a website called The Wisdom Page to make wisdom-related resources available to people worldwide. It has become quite popular. Last month the site had 14417 visits by people from 149 countries who viewed or downloaded documents, podcasts, and videos some 36159 times. And if you Google the word wisdom, http://www.wisdompage.com consistently comes up on the first page of the search returns — out of some 75 million+ pages containing the term. Anything else you might want to learn about my doings over the years is probably at http://www.wisdompage.com/aboutcop.html
Best wishes to you all. Cop

Thanks Cop!
