Jean Shepherd on CW, and Strange Propagation -- QRP!

From 1965.  Great CW stories from Shep.  QRP!  Shep running 2 watts on 20 CW, working DX. 

He discusses shortwave listening,  and predicted that CW shortwave listening would become more popular (sorry about that Shep). 

It was real hoot to hear the 1965 public service ad from NYC Mayor John Lindsey. 

The Kazoo CW was a bit hard to copy OM. 

The Stubborn Myth about USB and LSB

It  has been repeated so often and for so long that many of us have come to believe it.  I myself believed it for a while.   Like many myths, it has a ring of truth to it.  And it is a simple, convenient explanation for a complex question: 

Why do ham single sideband operators use LSB below 10 MHz, but USB above 10 MHz? 

Here is the standard (but WRONG) answer: 

In the early days of SSB, hams discovered that with a 9 MHz SSB generator and a VFO running around 5.2 MHz, they could easily reach both 75 meters and 20 meters (True). And because of sideband inversion, a 9 MHz LSB signal would emerge from the mixer as an LSB signal (True), while the 20 meter signal would emerge -- because of sideband inversion -- as a USB signal (FALSE!)  That sideband inversion for the 20 meter signal explains, they claim,  the LSB/USB convention we use to this day. 

Why this explanation is wrong: 

There is a very simple rule to determine if sideband inversion is taking place:  If you are subtracting the signal with the modulation FROM the signal without the modulation (the LO or VFO) you will have sideband inversion.  If not, you will NOT have sideband inversion.

So, you just have to ask yourself:   For either 20 or 75 are we SUBTRACTNG the Modulated signal (9 MHz) from the unmodulated signal (5.2 MHz)? 

For 75 meters we have:   9 MHz - 5.2 MHz =  3.8 MHz    NO.  We are not subtracting the modulated signal from the unmodulated signal.  There will NOT be sideband inversion. 

For 20 meters we have 9 MHz + 5.2 MHz = 14.2 MHz.     NO.  No subtraction here.  No sideband inversion.   

So it is just arithmetically impossible for there to be the kind of happy, easy, and convenient  USB/LSB situation described so persistently by the myth. 

---------------------------------

We discussed this several times on the podcast and in the blog: 

https://soldersmoke.blogspot.com/2015/05/sideband-inversion.html

https://soldersmoke.blogspot.com/2012/05/usblsb-urban-legend-debunked.html 

This myth shows up all over the place: 

We see the myth here: 

http://n4trb.com/AmateurRadio/Why%20The%20Sideband%20Convention%20-%20formatted.pdf

Here the web site owner warns that this is "highly controversial."  Really?  Arithmetic? 

http://9m2ar.com/lsb7.htm

The myth is very old.   Here is a clip from a 1966 issue of "73" magazine: 

https://worldradiohistory.com/Archive-DX/73-magazine/73-magazine-1966/73-magazine-01-january-1966.pdf

Finally, to my disappointment, I found the myth being circulated by the ARRL, in the 2002 ARRL Handbook page 12.3: 

The fact that the Handbook attributed this to a desire to "reduce circuit complexity" by not including a sideband switch should have set off alarms.  We are talking about hams who built their own SSB rigs, usually phasing rigs.  A sideband switch would not have added significant circuit complexity. I think they could have handled it. 

It is interesting that earlier ARRL Handbooks do not repeat this myth.  I found no sign of it in Handbooks from 1947, 1959, 1963, 1973, and 1980.  And I found no sign of it in several editions of that great ARRL book "Single Sideband for the Radio Amateur." 

For my next homebrew rig, I will build a rig that DOES do what the myth promises.  I will have the SSB generator running on 5.2 MHz USB.  The VFO (out of an old FT-101) will be running around 9 MHz.  So for 75 meters we WILL be subtracting the signal with the modulation from the signal without the modulation:   9 MHz - 5.2 MHz = 3.8 MHz.   There will be inversion.  This 75 meter signal will be LSB.   For 20 we will just add the 5.2 MHz USB signal to the 9 MHz  VFO.  There will be no inversion.  We will have a USB signal on 20.   I'm thinking of calling this new rig "The Legend." Or perhaps, "The Mythbuster."

M0NTV's Latest FB SSB Transceiver

Wow, Nick has a really wonderful rig and has made this great video to explain it. 

Elements that I really liked: 

-- The simple mic and compression.   Very nice. 

-- Termination Insensitive Amps.  TIAs Rule! 

-- Grey Altoid-like boxes. 

-- Diplexers!  Yes! 

-- Doug DeMaw S-meter. 

-- No AGC.  

-- Pentium CPU cooling fan. 

-- References to EI9GQ (I must get his book!) 

-- Al Fresco!   Good luck with boxing it up Nick. 

Santo Domingo Shack on 12th Floor Balcony -- SST QRP CW

June 2021.  We were in Santo Domingo, Dominican Republic.  At this point we were in a 12th floor apartment in the center of the city.  I would take my SST 20 meter CW transceiver and EFHW antenna out on the balcony.  I made no contacts from this location, but one of  my CQs was picked up by K9TM on the Reverse Beacon Network (see below).  All the other RBN spots were the result of calls from the eastern tip of the island. (Click on the RBN image for a clearer view.)

 

Good News! The Termination Event May Be Coming Soon! Solar Cycle 25 Could Rival Cycle 19!

Wow.  Cycle 25 might be as good or better than Cycle 19.  Pete cut his radio teeth on Cycle 19.  I was born during that cycle.  Let's hope these scientists are right!  See chart below.

Thanks to Thomas over at SWLing Post for alerting us to this important news.   

Tom's Receiver -- A 20 Meter Superhet Built From the Junkbox

Wow, this is really an amazing project.  It is so good that I'd like to believe that it is really "all our fault," but the credit obviously goes to Tom, the very intrepid builder.  In a more just world, Tom would be given a ham radio license solely on the basis of this project.  Great work Tom.  We look forward to more Solder Defined Radios from your workbench.   

Dear Bill and Pete,

I stumbled across your podcast a few years ago. I had no interest in
amateur radio, I was just looking for an electronics podcast that
actually discussed electronics (naming no names here, obviously).
Well, the inevitable happened, and some of your enthusiasm rubbed off
on me. I now find myself humbly enclosing a photograph of my first
homebrew receiver for 20m.

The project was one of those "spontaneous construction" affairs,
triggered mainly by breaking up an old satellite receiver (I've
honestly no idea what it was for) which yielded up several SBL1s and a
10.7MHz crystal filter - these form the key elements of the new
receiver. It's a full SDR (solder defined radio) of a conventional
single-conversion superhet arrangement. The chief abnormality is that,
because the IF filter is as wide as the proverbial barn door, I only
use "one edge" - the other half of the passband being provided after
conversion to baseband. Of course, that only works if there are no
massively strong stations in the 6kHz above where you're listening,
but it seems to be ok most of the time. It does give me the advantage
of being able to adjust the lowpass point of the AF signal by
adjusting the BFO, which is nice.

You'll notice there's a lot of "digital nonsense" in the picture, for
what's supposed to be an analogue radio. This "supervises" the two
VCOs: There is an FPGA which implements a pair of frequency meters and
an STM8 microcontroller which is in charge of adjusting the control
voltages to keep the VCOs where they should be. It's all slightly
roundabout because I wasn't clever enough to design a PLL which would
give the required resolution (and I wanted to do something "more RF"
than throw down a DDS chip). 
This gives me stability as well as fancy bells and whistles, like
numeric readout, tuning info via RS232, automatic scanning and
frequency presets. I've used a (cheap) industrial/automation style
encoder for the tuning control, which gives a lovely analogue-like
action.

Despite my best efforts (and a lot of ferrite in strategic places) I
wasn't able to keep all the digital spurs out of the receiver. So I
devised a dirty hack by way of a button which will shift the MCU an
DAC clocks to a different frequency. I can't remove the spurs, but now
I can hide them!

So far I've played with a "long" wire and a little shielded loop for
antennas - I'm in a first floor flat with a lot of noise locally, and
my plan is to get a loop up in the loft space (so the next project
might be a rotator!). I fancy maybe seeing if I've space for an
inverted V, too.

You'll notice that I've not attempted a transmitter. That, of course,
is because I'm not yet a licenced ham! However, I'm intending to put
that right sometime later in the year. Then - who knows - I might make
a contact!

Thanks for reading (although really it's the least you could do given
that this *is* all your fault) and I hope you've enjoyed hearing about
all the trouble your little podcast has got me into.

Keep up the good work gentlemen,
73 from South-West England.
Tom.

PS. I also have a copy of Bill's book, which I've very much enjoyed.

Pete's Drakes

Pete Juliano N6QW has on his blog two very nice videos about the Drake A-line.  

As long-standing fanatical fan of the Drake 2-B, I was struck by the similarities between the 2-B and the R4 seen in Pete's video:  

-- The S-meter is the same. 

-- The passband tuning control and indeed the visible internal circuitry for the passband tuning seem to be the same.  

-- Drake even used the same "hook" for selectivity selection.   

The transceive feature with the T4 seems very nice.  

Pete's first video is above.   Pete's second video, showing his first contacts with the newly acquired A-line, can be seen here:

The Perpetual Troubleshooter -- John F. Rider -- W2RID

https://en.wikipedia.org/wiki/John_F._Rider

To Mars in 1964 -- Building the Camera and Radio Systems

This is a really excellent video showing how JPL engineers and technicians designed, built and tested the first video camera system sent to Mars. 

-- It was essentially a Slow Scan TV system built around a Vidicon tube. 

-- Data was sent back in digital form. 

-- The first Digital-Analog conversion was done using COLORED CHALK!

-- The method used to protect the Vidicon tube from vibration was derived from the packing material used to mail the tube to JPL from Texas. 

-- During testing, JPL had all the circuitry spread out in what we would call "Al Fresco" style. 

Thanks to Dan Maloney at Hack-A-Day for alerting us to this.  Dan has an excellent article about the mission here:

Remastered! The Secret Life of Radio -- With Updated Comments from Tim Hunkin

Thanks to Stephen 2E0FXZ for alerting us to this important video. 

We first posted about the original many years ago.  We were delighted to learn that they have remastered the video and added 10 minutes of retrospective commentary from Tim Hunkin.  

Here are some of my reactions after watching the updated version:

-- The Marconi videos were amazing.   I actually met Elettra at a diplomatic reception in Rome.  

-- I was pleased to learn that Marconi was trying to "call up" Mars.  FB OM. 

-- My son Billy and I sat in that same Royal Institution auditorium where, 100 years before, Oliver Lodge had demonstrated spark gap technology. 

-- Tim's comment on the connection to supernatural beliefs was right on the mark.  We found out that the house we lived in in London was a center for occult beliefs and practices. 

-- Those square lantern batteries brought back fond childhood memories. My first power supplies.

-- The Rexophone -- used by Rex. 

-- Very cool of Tim to homebrew a coherer.  Extra credit for that.

-- One of the capacitors looks familiar.  EF Johnson? 

-- I agree with Tim -- crystal radios are a must-build for true radio hams.  And do it with galena and a cats whisker. 

-- Finally, the RCA ad introduces a term we might want to surreptitiously enter into the Enhanced SSB lexicon:  That "Golden Throat" sound.   

QRP - QRP Contact from Dominican Republic

It took some brass pounding on my homebrew key, but on May 28, 2021 I made a real QSO from the eastern tip of the island of Hispaniola.  KJ4R came back to my CQ near 14.060 MHz. I was running just 1-2 watts from my SST transceiver to an end-fed half wave antenna. Ed KJ4R was in South Carolina running 5 watts, also to an EFHW antenna.  TRGHS.  Thanks Ed.  And thanks to Bob Scott KD4EBM and Wayne Burdick N6KR.

Farhan's sBITX -- Combining SDR with the Traditional Superhet

Here is Farhan's amazing presentation to the virtual 2021 FDIM event.  There is a lot of tribal knowledge in this video.  Lots of old and new technology.  I was especially intrigued by Chris Trask's Kiss mixer.  Farhan's discussion of simple Arduino-based speech equalization and compression made me think that I have work to do in this area. And of course, Farhan's whole discussion of how to bring SDR into -- literally into -- the circuitry of a uBITX is really cool and very educational.   

TRGHS: K3ZO heard from the Dominican Republic

We arrived in the DR just yesterday, and this morning was my first chance to do some ham radio stuff. I fired up my old Sony SW receiver (the one with the busted BFO fine tuning control) and tuned to 20 meters. The very first station I tuned in (after adjusting the BFO with my Swiss army knife) was talking about the Cicadas.  He described weather similar to that which we had just left in Northern Virginia.  Then I heard the call:  K3ZO.  It was Fred Laun up in Maryland!  When I first came to the DR in 1992, the locals were talking about Fred as if he had just recently past through.  I learned, however, that he had been there during the 1960s!  He had left quite an impression.  He had saved one of the local hams during the 1965 political violence.   I gave that same local ham some Vibroplex parts so that he could fix up an old bug that Fred had left him. 

Wow, it was really cool to have Fred Laun be the very first ham I hear during this trip. The Radio Gods Have Spoken.   We need to spend more time (especially winter time!) in the DR!

I have a video of this listening session that I will post when we get back to Virginia.

Parasets, Parachutes, and Tubes in "A French Village" Season 3

https://en.wikipedia.org/wiki/Un_village_fran%C3%A7ais

In season 3, Episodes 7 and 8, resistance members parachute in from London.  They are equipped with what looks a lot like a paraset.  One of their tubes develops an open filament.  The Germans engage in radio direction finding.  The Morse code is fairly good (but not great).  All in all, there is quite a bit of radio-related material. 

"A French Village" is a very well-done series.  But it is (of course) quite dark. 

Michigan Mighty Mite, Joy of Oscillation, and the Color-Burst Liberation Army in Washington State

 

Perhaps its the result of a vaccine-induced relaxation of COVID tensions, but for whatever reason we are seeing a resurgence of interest in the Michigan Mighty Mite and the Color Burst Liberation Army. 

Dan AF7O describes his excellent MMM CBLA adventure here: https://af7o.campclan.net/?p=144  Extra points for the use of George Dobbs' Ladybird book technique, and for the 3D printed variable cap holder (made by Dan's son). 

Yes Dan, rebuild that antenna, build an LP filter, and get that MMM on the air.  At the very least you can get some reports from the Reverse Beacon Network.  And, as Jack NG2E recently demonstrated, it is possible to make contacts with a simple rig like this:

Cicadas Arrive in Northern Virginia

Usually the only bugs we talk about here are dead bugs (components with their leads up on circuit boards) or perhaps CW keying devices.  But in the last podcast I mentioned  the arrival in Northern Virginia of Brood X Cicadas.  They are coming to the surface after 17 years underground.  This morning I found this amazing animation that explains the lifecycle of these fascinating creatures. 

This morning Elisa mercifully took the time to take several dozen of them off the tires of her car.  

Here is the animation.  Just scroll down to follow the life cycle. 

Be sure to turn on the audio!

The SST QRP Transceiver

 

Click on the schematic for a better view

Bob KD4EBM recently sent me an amazing package of radio goodies.  Included was a little metal box not much larger than a deck of cards.  It is a 20 meter SST transceiver designed by Wayne Burdick N6KR during the late 1990s.  This transceiver is built around three NE602 Gilbert Cell mixer chips.  It arrived in my shack as I was struggling to understand the Gilbert Cell.  TRGHS.  It also put me back on the path of QRP CW righteousness.    Thanks Bob.  Thanks Wayne. 

I e-mailed Wayne Burdick (now of Elecraft fame) to tell him I was now using the rig he had designed so long ago.  Wayne e-mailed back, saying that the SST was the smallest "real" radio that he had ever designed.  SST stands for Simple Superhet Transceiver. 

I've been using the SST every day for the last week or so.  It is a pleasure to operate.  I'm using it with the key from India that Farhan brought for me.   It is truly QSK -- the receiver stays on when I transmit.  I've never used a QSK rig before and I can now see the big advantage that this provides:   When I am responding to a CQ, I can immediately hear if the other guy put out another CQ or respond to someone else -- I can stop calling at that point.  My first contact with it was with F6EJN.  Again, TRGHS. 

I made two small mods to the SST:  I added 1 uH to the RFC in the VXO; it  now tunes 14.053 -- 14.063.   And I took out a noise blanker that had been installed. Removing the noise blanker left an ugly hole in the front panel which I promptly filled with a completely cosmetic machine screw. 

Here's the manual:

HRDX Interviews Paul Taylor VK3HN

Wow, Paul Taylor, VK3HN is working on homebrew rig #11.  FB.  

This interview was quite thought-provoking. 

-- I agree with Paul about the importance of not being dogmatic about 

always staying under 5 watts.  It sounds like Paul is having fun with his 

100 watt SOTA project. 

-- It was great  to hear that Leon VK2DOB is still active in ham radio and running a QRP company in VK.  FB.  An article by Leon on CMOS mixers in the summer 1999 issue of SPRAT played a key role in my understanding how switching mixers really work.  I put Leon's diagram in my book SolderSmoke -- Global Adventures in Wireless Electronics. 

-- On blowing up the finals in simple HB gear.  The first real transmitter that I built was the VXO-controlled 6 watter from QRP Classics by the ARRL.  It had a 36 volt Zener diode across the collectors of the final.  This was to prevent the kind of final destruction Paul suffered up on that summit:  "D2 is used to clamp the collector voltage waveform to protect the output transistors if the transmitter is operated into an open circuit or high SWR antenna system."  Maybe we should revive the use of that simple SWR protection circuit, especially for SOTA rigs. 

Bill N2CQR Talks to Dean KK4DAS about the Simple SSB Group Build

Dean KK4DAS visited the N2CQR SolderSmoke shack.  We talked about a lot things including chess, Mars, and AI.  Dean is an amazing guy -- he used to work at NASA's Jet Propulsion Laboratory and a couple of times  actually spoke with Richard Feynman. We also shot a video about the Vienna Wireless Society's group build of Pete Juliano's Simple SSB transceiver (video above).  

This group build all started with Dean's build of Pete's rig.  He built his early in the pandemic, while on furlough from work,  thus the name "The Furlough 40." That makes all of this very much a quarantine effort. As we have learned, dark clouds often do have silver linings. 

For more details on the group build, check out Dean's blog:

The Homebrew Spirit of the Radio Amateur

I just liked this picture.  It seems to capture the pride and satisfaction that comes from getting on the air with homebrew gear. It's obviously a simple QRP station, but it is all homebrew.  And -- from the QSL cards on the wall -- we can see that he has had some success with it.  The map on the wall is of the United States and the QSLs are from the east coast and the mid-west, so my guess is that he's probably on 80 or 40.   FB OM.  

The Joy of Fixing Broken Things (a really amazing video)

This amazing 10 minute video captures very well the joy of fixing broken things. It comes to us through a recommendation from Paul VK3HN in Melbourne, Australia. Thanks Paul.

I hope we will see more from Van Neistat.  He already has a bunch of videos on his YouTube channel:   https://www.youtube.com/channel/UC5mPJA4y5G8Z6aNkY6AxgAw

I often tell the story of the OT (probably now an SK) who at hamfests would ask if a piece of old gear was working. If the vendor answered honestly and said no, OT would reply, "Good, I pay extra for that."  He too liked to fix things.

Chuck Penson WA7ZZE, Heathkits, and the Titan Missile Museum

                                             WA7ZZE Shack

The video above popped up in my Facebook feed today and reminded me of Chuck Penson WA7ZZE.  Chuck is the author of a wonderful book on Heathkits (and several other books). 

The Titan missile explosion (not of the warhead) in Arkansas is described in an excellent but horrifying book entitled "Command and Control" by Eric Schlosser.

https://www.amazon.com/Command-Control-Damascus-Accident-Illusion/dp/0143125788/ref=sr_1_4?dchild=1&keywords=Command+and+control&qid=1620478171&sr=8-4 

PBS made a video out of the book.  You can watch it here: 

https://www.pbs.org/video/american-experience-command-and-control-film/   

Here's an interesting article on nuclear weapons tourism.  It has a great title. 

https://www.nytimes.com/2007/01/05/travel/escapes/05atomic.html

It is easy to see how an interest in ln old technology would lead someone to both Heathkits and Titans.  I get that.  But on the other hand the Heathkits and the Titans are at completely opposite ends of the humanity spectrum:  Heath made friendly technology that ultimately brought people together on the ham bands.   We know that the Titans were supposed to do. 

In any case it was great to be reminded of Chuck WA7ZZE.  We last posted about Chuck more than 10 years ago: 

http://soldersmoke.blogspot.com/2009/08/chuck-penson-heathkits-nukes-and-qrp.html

In a comment to that post, Steve "Snort Rosin" Smith WB6TNL noted that Chuck had spoken at the 2009 CactusCon hamfest, and that the club pledged to put his presentation on-line.  But Google and I can't seem to find it.   Do any of the Scorpions or anyone else out there know where Chuck's hamfest talk is? 

Bob KD4EBM has been out there.  He reports that hams can bring their rigs and make use of the Titan site's large Discone antenna:

"Adventures in Electromagnetism" Video by Julius Sumner Miller

This guy is quite a character, with a real knack for describing physics.  At the start of this video he says that these kinds of adventures are "good for the spirit and the soul."  Right you are Professor Miller.  I am currently recovering from a minor back injury.  It is nothing serious, but it has delayed the production of the SolderSmoke Podcast #230.   These videos are, for me, just what the doctor should have ordered.  

I liked Miller's references to Michael Faraday. 

There are many videos on the Julius Sumner Miller YouTube Channel.  They are indeed "good for the spirit and the soul."   Thanks to Hack-A-Day for alerting us to this treasure trove.
