WD-40, a Hard Drive, a Coat-Hanger Antenna, Dumpster Diving, and Amateur Radio Satellites from the Azores

 

Last month I was talking to Ira VP2EIH on my new 1712 SSB rig.  Ira is interested in satellites.  Talking to him caused me to dig up some old material about satellite operations.   Here is a 2003 QST article about working the satellites from the Azores: 

http://www.gadgeteer.us/AZORESSP.HTM

Regarding the usefulness of WD-40, during my time in the Azores John EI7BA once told me that WD-40 is, "the Pope's pee!"  Apparently that is high praise in Ireland.  It is indeed good stuff. 

Messias CU2BJ is a Silent Key.  I hope Ray CU3GC, WL7CDK is doing well.

Another M^3: The Michigan Micro Mote


Move over Michigan Mighty Mite and Mate for the Mighty Midget.   There's a new M^3 in town.  And it is SMALL. 

Hack-A-Day had an article on this today, and while it seems only tenuously connected to ham radio, I found it intriguing.  

Check it out.  Who knows, someday people may be operating in "dust mode":

SolderSmoke Podcast #216 Is Available: BITXs, Paesano, Paraset, ET2, Antuino, Mailbag

Bill's uBITX with HB keys and the mic that used to be the podcast mic! 
SolderSmoke Podcast #216 is available 

21 December 2019

HAPPY HOLIDAYS TO ALL! 

http://soldersmoke.com/soldersmoke216.mp3

Pete's Bench 
Sprat Article
BITX 40 Fun
ZL2BMI Rig
Paraset.   Three tubes!  Almost an ET-3!

Bill's Bench
ET-2 Adventure over,  Rig on the wall
Final QSO count. 20   3 "random" 
Last QSO with AA8OZ
Lessons learned:  100 mW not the problem. Crystal Control cramps your style. 
N0WVA regen amazingly effective.
Tried for the Sunrise Net.  Walter sent me some crystals.  

On to the uBITX. 
Accidentally wiped out calibration and BFO settings. 
Had to do recalibration and reset BFO. 
Learned a lot about the rig. 
How they did CW and how they do it now. Shift TX?  Or shift RX?  Or just shift BFO on RX? 
How all the signals end up as upper sideband.  Only one BFO freq.  Very cool. 
TalentCell 12 V Lithium Ion 3 AmpHour battery. Size of a deck of cards. 
Inspired by Peregrino -- I ordered EFHW Tuner from QRP Guys. 
Homebrew Straight Keys

Antuino upgrade 
SMT soldering. 
Back to Arduino Nano and the IDE.  
A very cool tool. 
Antuino filter analysis.
Version 6 of uBITX out. 

The "Watt Meter" DC power meter.  Very useful.  8 bucks.  LINK:
https://www.ebay.com/itm/Digital-DC-combo-Meter-LCD-Watt-Power-Volt-Amp-RC-Battery-charging-Analyzer-M/152339793114?fbclid=IwAR0u9SlZi2Dm6zOJyZt4fDTu7w_pjBIEYD_FiNfLymxtQUbMjcNHjfB17P0

SPRAT, balloons and hardcore homebrew hydrogen. 

MAILBAG
VK3HN's AM receiver.  I ordered 6kHz 455 kHz filters from Australia. 
Dean's MMM
Peter VK2EMU   Hertz not hertz. 
Ben KC9DLM LTSpice YouTube Videos
Steve Silverman  Electroluminescent Receiver Kit
Lyndon N0LFX back to listening.  FB OM
Steve M0KOV built a pill bottle variometer.  Did you get the regen going? 
Anthony VU3JVX   FB HB uBitx.  
Allison KB1GMX  Great to hear from her
Leif WB9IWT -- helped me trouble shoot my uBITX (BFO was low)
Mike EI0CL  old buddy from Azores days.  Recognized his voice on 20.  Great QSO.

Homebrew Processor with Discrete Transistors and LEDs



I've been working with an Arduino today.  Seeing this video makes me feel like such an APPLIANCE OPERATOR.  FB OM!  No store-bought mystery boxes for him! 

Thanks to Steve N8NM for alerting us to the magnificent project.

A Major Change For SolderSmoke: Introducing the WireWrapRap Podcast!


A New Direction for SolderSmoke
Introducing Our New Podcast:  “WireWrapRap”


Attentive listeners have probably noticed that for some time now the podcast has been drifting in a new direction.  Some have been concerned by this change.  I myself, as you know, have shared in many of these misgivings.   But I have become convinced that it is time for a major change in direction.  We've been doing this for more than ten years -- we are one of the oldest ham radio podcasts.  It is time for a change.
A number of people have encouraged me to make to this change.   My co-host Pete Juliano N6QW is clearly the main influence.  Pete has made me see the errors of my Ludite ways.  He taught me that it is time to put away the Dymo tape and get with it with glowing numerals.  Whenever I started getting enthused about VXOs or about Permeability Tuned Oscillators using brass screws moving through hand-wound coils, Pete was there to remind me of the beauty, simplicity, and efficiency of Arduino Microcontrollers and Si5351 chips.   Paul Darlington M0XPD contributed an element of old world legitimacy to this push for modernity. Tom Hall AK2B was another influence -- whenever I was on the verge of quitting, he’d Skype in from the Big Apple and get me back on the digital track.  And we can’t forget Farhan over in India – as soon as he started putting Arduinos and Si570s in his Minima, I knew this was really, as the kids say, “a thing.”
So anyway, it is time for a change.    I know many of you may find this shocking, so it is probably best for me to just go ahead and say it:  We are changing the name of the podcast and we are changing its focus.
n  Instead of SolderSmoke, the new name will be “WireWrapRap.”   Wire wrap is the solder-less wiring technique often used in computer circuitry.  We hope that the “Rap” thing will be especially helpful in attracting young people – especially those Maker Millennials -- to the show.  And, you know, soldering just seems so 20th century.     

n  Instead of traditional homebrew radio, the show will be focused on Mini Computers (especially the Raspberry Pi), Software Defined Radio, Digital Signal Processing, Microcontrollers (especially the Arduino), and the use of smart phones in ham radio
n  Obviously this implies a move away from minimalist radio and QRP.  So yes, we are going maximalist and we are going QRO. And we are getting more involved in contesting (see below).  

Now I know what some of you are thinking – that this must be part of our long-standing quest for sponsorship and that this is all about money.  But that’s only part of it.  Yes, we have secured a lucrative sponsorship arrangement with a company involved in microcontrollers, small computers and smart phones that is focused on the millennial market.  But we’re really doing this for the good of our listeners. 
Don’t worry, you will find many of your favorite parts of SolderSmoke in the new show.  They will be the same, only different.   For example, instead of the “Bandsweep” segments that we used to do, now we are going to have “Codesweep”  (and it’s not about Morse).  Where we used to have SolderSmoke Mailbag, well, don’t worry -- we are going to continue to have a segment that will allow for listener input.  We going to call it “Pi Hole.”  We’ll only be accepting listener input via TEXT messages or Tweets – we are, after all, trying to be modern.  Along the same lines, we will be distributing the podcast exclusively via Soundcloud.  So get with it gentlemen! Get into the cloud!
In the new and improved podcast we want to explore the new and exciting digital modes.  We plan segments on all the new ones: PSK-99, Opera, WSPR, SNICKR, Throb, Thor, Piccolo, Oreo, Oregano,  you know, all those weird sounds you’ve been hearing near what used to be considered the CW portion of the band.  It will be such fun!  I can’t wait to decode some Oregano!
Smart phones, are, of course, the future of ham radio, and we intend to be fully into those little magic boxes.  I don’t know if you guys realize it, but all of that ugly dusty junk in your shack can be replaced by a few lines of code from the App Store.  That room you used to call “the shack” can be converted into the Yoga studio or knitting room that your wife has been longing for!  Now you can carry your station with you wherever you go and autonomously participate in contests from stations around the world.  Imagine the thrill of learning that while you were playing golf or bowling, you were also WINNING a major DX contest from a “station” in Ulan Bator. And that ALL of your reports were 59!   It’s like owning your own ham radio drone!  Congrats old man.  YOU WON! Welcome to the 21st century! That’s the kind of operation we are going to explore on WireWrapRap!
For those of you who are worrying that we might be abandoning our microphones, have no fear my friends, Pete and I remain committed phone operators. Only now, it will be DIGITAL VOICE.   We’ll be squeezing our dulcet tones into a mere 800 Hz of bandwidth.  This way we both sound exactly the same.  Heck with this new technology everybody will sounds the same.  How cool is that!   We’ll all sound like a mix of Stephen Hawking’s synthesizer, Apple’s Siri, and MTV's Max Headroom.   The AM guys and the Enhanced SSB crew may need some time to get used to this, but c’mon fellas, it is time to get with it!  There will be no more need to tweak all those menus for “presence” and “brightness” and “mid-range.”   Heck no, we’ll all sound the same!  Progress my friends, PROGRESS!
As I said, I had my doubts about this.  But over the weekend I walked into the TV room and Elisa happened to be watching one of those “inspirational self-help” speakers on Direct TV, and you know what?  He made a lot of sense. Change IS good!  We have to EMBRACE the future!  Impossible = “I’m possible!”  Yea!  So thank you Deepak Chopra!  Thank you Pete Juliano!  And welcome --  all of you -- to the WireWrapRap!

Kansas Mighty Mite



Greetings Bill

I have been a bit ill,  but finally found some time to work on my Meara Mighty Mite, which i wish to call it as it was by the grace of Bill Meara that I am able to play a part in the Colorburst Revolution could begin.

I just wanted to share some pictures from the bench of my progress, which is not yet fit for the ether.



I originally wanted to build a really unique design. I have a tendency to complicate things. The more simple it is, the more complicated I tend to make it. After a lot ambitious failed starts, I decided that the best thing to do is to keep it simple. In fact, I would say that I was "over-noodling" this one. So I just started building.

I use copper clad PCB, which I get for very cheap from an ebay seller named abcfab. I use a tool I made to cut islands by hand. Information can be found about this method on my blog.
I am almost embarrassed to share photos of my build, especially after seeing such wonderful designs as you have featured on the webpage. But the excitement is just to great, so here it goes:

I build ugly circuits and I'm proud of it.

I haven't build the LPF yet and wouldn't put it on the air without one. 

Thanks for all the great inspiration and for inspiring a revolution of colorburst liberation!

I want to share something from Solid State Design for the Radio Amateur, W7ZOI & W1FB, page 19
"All of the circuits shown are aimed at reasonable stability, but have relatively low output power. It is possible to bias many of these circuits higher to obtain outputs of up to perhaps 1/4 watt. However, thermal stability is often severely degraded, chirp is introduced if the oscillator is keyed, and the user stands a chance of damaging the crystal from excessive rf current. It is not recommended that a single oscillator stage be used as a simple transmitter. The addition of an amplifier is so straightforward, and the system efficiency is so much better, that the minimal simplicity is not of value."
That may be true, but the Mighty Mite is for learning and getting our feet wet. Still it may be interesting to point the above out or talk about it.

Also, I'm curious to know which schematics everyone is using. The famous Easy QRP transmitter on the QSL page, perhaps DeMaw's from QRP notebook (available on archive.org in pdf form for free).

73, keep your iron hot and stay fluxy,

-KE0BFF, Lawrence KS.

Manhattan Mighty Mite: "Rockin' the Big Apple on 3.579"



Dave W2DAB got his Manhattan Mighty Mite oscillating nicely!  Hooray!  

Check out Dave's report on his Mighty Mite adventure: 

http://w2dab.bamford.net/

So far we have sent out 20 colorburst crystals.  Already we have two circuits oscillating (not counting Pete's and mine). 

CLA is on the march! 

E-mail from Dave: 


Dear Bill & Pete:

Thanks for all your help, I can joyfully announce the birth of my first Michigan Mighty Mite, Oscillating at the frequency of 3.579!  Yes, Pete’s sage advice to flip the coil over was a great help and also my good friend from Vermont (A Michiganian by birth ).  OK, so Bill… you remember your most embarrassing moments in home-brew? Well, here’s mostly what happened: I was reading the article I found online and somehow got 40 meters stuck in my head even though your colorburst was for 80 - So I build a 40 meter coil.  When I realized my mistake I thought - well why not build two of these so I pulled out the Colorburst and put in a Norcal 7.040 and then built a new board with a new 80 coil oriented properly and the pic below is the one you see.  Now I have two Mighty Mite’s that work, how great is that.

My next goal is to continue forward using Pete’s Build Something Video’s, so more fun to come.

I will post a video on my blog of the 80 Meter Colorburst Michigan Mighty Mite uttering it’s joyful tones, but for now I’ve put a lovely photo at the bottom.

Success is sweet when you hear the sounds of the beep!

Cheers and 73 Gentlemen

Dave

The Raspberry e-Bay Multi-Mode Beacon of M0XPD


From: Paul Darlington 
Subject: Multi-mode QRSS beacon on the Raspberry Pi
To: "Bill Meara" 
Date: Sunday, January 20, 2013, 8:32 AM

Hi Bill

Inspired by recent comment on your SolderSmoke blog, I got myself a DDS module from eBay.

Today I lashed it up to my new Raspberry Pi and now have CW and Hellschreiber pumping out on 40m.

I hope others will forgive my greedy use of the spectrum in transmitting "m0xpd :- Raspberry Pi" in Hellschreiber.

The story is here: http://m0xpd.blogspot.co.uk/2013/01/multi-mode-beacon-on-rpi.html

Move over Altoids Tins! Legos for Raspberry Pi Case

Too bad the Raspberry Pi board is a bit too big for our beloved Altoids tins.  It would have been a very fitting match:  British board in a British box.   A twelve year-old has solved the problem with Legos:  http://blog.makezine.com/2012/06/11/lego-raspberry-pi-enclosure/
Will this lead to raids on the toy boxes of the grandchildren of SolderSmoke fans? 
Billy's RasPi is running nicely (but no Legos for him).

Homebrew CPU

From the site: I understood these computers well, but the processor itself was still a mystery. I wanted to understand that part too, at the logic gate level. I sometimes thought about making my own processor, and designed small instruction sets and instruction formats. But the task seemed beyond the grasp of a hobbyist such as myself.

OK, OK, I won't cut open the USB cable,,,


I foolishly thought I could just open that baby up and work on it like the old serial port cables. I have been told (many, many times) that this can't be done. Man, you know things are getting complex when the cables have schematics. G8INE sent me the above diagram of a USB-Serial converter cable. E-bay here I come!

Some Tech Humor

Ron Barrett

Apparently Pluto's demotion from planet status might have been a bit unfair. Researchers say that the rival to Pluto that was discovered six years ago is actually smaller than Pluto.

And I thought this BBC skit on computer problems would yield a few chuckles from the SolderSmoke community. (For U.S. readers: Orange is a big ISP/mobile phone provider in the UK and elsewhere.):

The Arduino Documentary

Arduino The Documentary (2010) English HD from gnd on Vimeo.


Embedded controllers may seem a bit far afield for SolderSmoke. After all, I kind of gave up on surface mount, and have pretty much resigned myself to "hardware defined radios." (Someone sent me a picture of a T-shirt that kind of captured the sentiment: "I PROGRAM IN SOLDER!") But still, for a number of reasons I find Arduino intriguing. Aside from the amazing things you can do with this device, I like the homebrew, hands-on aspect of it. As you will see in the documentary, there is a real spirit of international collaboration in Arduinoland -- Italians, Spaniards, Colombians, Americans all working together on the project (the documentary itself is also available in Spanish). I also like it because it has its roots in Italy. So, even if you are not into embedded controllers, check out the documentary. I think you will like it.

Black Boxes No More! Cracking Open CPU Chips!

You guys have to see this. These guys have opened up some old CPU chips and have drawn the circuit diagrams for all the transistors. Then they made models of the circuitry. And they can runs programs on the models! From the site:

Have you ever wondered how the chips inside your computer work? How they process information and run programs? Are you maybe a bit let down by the low resolution of chip photographs on the web or by complex diagrams that reveal very little about how circuits work? Then you've come to the right place!

The first of our projects is aimed at the classic MOS 6502 processor. It's similar to work carried out for the Intel 4004 35th anniversary project, though we've taken a different approach to modeling and studying the chip. In the summer of 2009, working from a single 6502, we exposed the silicon die, photographed its surface at high resolution and also photographed its substrate. Using these two highly detailed aligned photographs, we created vector polygon models of each of the chip's physical components - about 20,000 of them in total for the 6502. These components form circuits in a few simple ways according to how they contact each other, so by intersecting our polygons, we were able to create a complete digital model and transistor-level simulation of the chip.

This model is very accurate and can run classic 6502 programs, including Atari games.

I had some technical (operator!) problems with Audacity this morning. Podcast 129 should be out tomorrow morning.

Computer Successfully COOKED!

I must say, this was one of the strangest repair jobs I've ever had: You may have heard the background: My wife's three year-old Sony Vaios 'puter suddenly came up with really serious graphics problems. A quick Google revealed that lots of computer have this problem (lots of brands... including Apple). We took the computer down to the Sony store and they got all legalistic on us. Yes, it was clearly the video card. Yes, Sony had agreed to fix the video cards. BUT unfortunately Sony had not put our model number on their list of computers that they would fix. So they wanted to charge us $400 to fix the problem. No thanks Sony! Goodbye Sony!

Inspired by the iFixit poster on the wall of my shack, I did some more Googling. Soon I'm reading messages from all around the world recommending that I -- in one way or another -- cook the computer. But why? Is the problem IN the GPU chip? Or is it in the solder connections between the chip and the board.

Gents, you'll be pleased to learn that this is a SOLDERING problem. Looks like NVIDIA used a bad mixture of soldering types. There is apparently little blobs of solder on the baord, and little blobs of solder on the chip. LOTs of little blobs. Surface Mount to the MAX! But they used two different solders and this causes the connections to fail far more quickly than they should have. Here are the details:
http://s0.2mdn.net/2994486/Polycom_inquirer.html?rfp=http://www.theinquirer.net/inquirer/news/1004378/why-nvidia-chips-defective
Enter the oven solution. The idea is to simply re-heat the chip and make the solder at the connections melt again!

YouTub presents lots of different ways of doing this. I like the idea of using a bright lamp to administer the heat. I used a 120 watt Halogen beam lamp. The kind that you see on lights for the backyard. I tested its heating properties on a chunk of 60/40 rosin core solder. At about 1/2 inch it melted the solder in 30 seconds.

I put the beam on the TOP of the chip and gave it about 30 seconds of burn. Then I administered some heat sink compound, vacuumed out the fan, and put the computer back together.

IT WORKED! That computer is now working just as it had before. This was a very satisfying repair, but there was no real troubleshooting, so it wasn't really up there with my favorite fixes.  You can check out www.computerrepairtraining.org if you want to learn more about fixing computers.

I'll put one of those cheap laptop coolers underneath it. I'm guessing that this thing will go for another few years.

Thanks to all who provided advice. Thanks to ifixit for the inspiration. Thumbs down on Sony. BOOOOO! HISSSSSS!

Should I Put My Sony Computer in the Oven?

In a recent podcast I asked for help with my wife's ailing Sony Vaios computer. The graphics card has gone toes up. Sony acknowledges that they had BIG problems with the NVIDIA graphics cards, but even though our computer has an NVIDIA graphics card and has all the symptoms that come with the NVIDIA graphics card problem, because our particular model is not on their list of affected computers, they won't fix it. (Mental note: Don't buy any more Sony computers!)

Anyway, KB1SNG recommends putting the mother board in the oven:

As crazy as it may sound, you could try putting the motherboard in the oven.
Many people (including myself) have tried this with success.
I did it a while ago, and I can't remember if this ( http://www.overclockers.com/forums/showthread.php?t=606658 ) was the guide I used or not, but it should suffice. If I find the other link, I'll post it here.73,Nick LaPointe, KB1SNG

Rogier provides this useful info:

NVIDIA lost a lawsuit with regards to a faulty graphics Chip. Caused by the fact that when they started using lead free solder.
This new solder turned out not as heat resistant as thought and tends to break loose causing the chip to fail.
He continues:
Hmm that's a bold move to put the board in the oven.
On the other hand there is little to be lost and you might give it a try.
Thinking of it I rather apply the heat locally. Isolate the Graphics chip from the rest and apply a short blast of heat to the chip.
Perhaps with a hot air paint stripper....

So what do you guys think? Should I pop it in the oven? Or apply some heat? I kind of like the idea of fixing a problem caused by lead-free solder (yuck).

Receiver Success! Combining Computers and Homebrew Radio

Well, it turns out that yesterday was a GREAT day for a new receiver. When I got home from work 30 meters was open. I fired up the new receiver and the FLDIGI program. Immediately I started to see and decode PSK-31 signals. I quickly switched over to the WSPR program and right away I could see the little two minute WSPR sigs. Here is what my screen looked like:

The program also began to automatically upload reports to WSPR HQ. Here is the report I found on the WSPR web site this morning:

I know all this WSPR and digi stuff often seems to be very computer-centric, and very "appliance radio," but I think this little project shows how we can have the best of both worlds: This rig combines a laptop computer and some pretty sophisticated software with a VERY simple, discrete component, homebrew direct-conversion receiver.

OK. So you see that I left a lot of space on the PC board. That's where the DSB transmitter (for WSPR and possibly PSK-31) will go.

BTW: You can keep an eye on my reception reports by going to the Database section of the WSPRnet site and plugging my call (I0/N2CQR) into the "reporting station" block. I'll leave the receiver on today.
