Kludge: Rube-Goldberg Heath-Robinson Ad-Hockery



Wow!  "Ad-hockery... verging on being a crock."  That sounds like my building technique!  I thank Kevin for sending this, but I admit to now being more confused than ever.

Bill:

A snippet from my kluge research.  This was a word I learned from my dad who told me he had heard it first used in the 1930s.  Here is where I find a divergent meaning with the new word kludge which I have often heard pronounced as rhyming with sludge.  I was asked why I pronounced it with the d as silent.  I asked why I should pronounce a letter which was not even in the word.  Thus my introduction to the new word kludge which means something very different than what I had learned from my father.  While a kluge is something clever a kludge is an ad hoc and usually buggy hack. 
I found a little supporting evidence for the etymological timeline. To whit:


Source: The Free On-line Dictionary of Computing (2003-OCT-10)

kluge

   /klooj/, /kluhj/ (From German "klug" /kloog/ - clever
   and Scottish "kludge") 1. A Rube Goldberg (or Heath
   Robinson) device, whether in hardware or software.
   The spelling "kluge" (as opposed to "kludge") was used in
   connection with computers as far back as the mid-1950s and, at
   that time, was used exclusively of *hardware* kluges.
 
   2.  A clever programming trick intended to solve
   a particular nasty case in an expedient, if not clear, manner.
   Often used to repair bugs.  Often involves ad-hockery and
   verges on being a crock.  In fact, the TMRC Dictionary
   defined "kludge" as "a crock that works".
 
   3. Something that works for the wrong reason.

   4. (WPI) A feature that is implemented in a rude manner.
   In 1947, the "New York Folklore Quarterly" reported a classic
   shaggy-dog story "Murgatroyd the Kluge Maker" then current in
   the Armed Forces, in which a "kluge" was a complex and
   puzzling artifact with a trivial function.  Other sources
   report that "kluge" was common Navy slang in the WWII era for
   any piece of electronics that worked well on shore but
   consistently failed at sea.
   However, there is reason to believe this slang use may be a
   decade older.  Several respondents have connected it to the
   brand name of a device called a "Kluge paper feeder" dating
   back at least to 1935, an adjunct to mechanical printing
   presses.  The Kluge feeder was designed before small, cheap
   electric motors and control electronics; it relied on a
   fiendishly complex assortment of cams, belts, and linkages to
   both power and synchronise all its operations from one motive
   driveshaft.  It was accordingly tempermental, subject to
   frequent breakdowns, and devilishly difficult to repair - but
   oh, so clever!  One traditional folk etymology of "klugen"
   makes it the name of a design engineer; in fact, "Kluge" is a
   surname in German, and the designer of the Kluge feeder may
   well have been the man behind this myth.

   TMRC and the MIT hacker culture of the early 1960s seems to
   have developed in a milieu that remembered and still used some
   WWII military slang (see also foobar).  It seems likely that
   "kluge" came to MIT via alumni of the many military
   electronics projects run in Cambridge during the war (many in
   MIT's venerable Building 20, which housed TMRC until the
   building was demolished in 1999).

kluge /klooj/ [from the German `klug', clever; poss. related to Polish
'klucz' (a key, a hint, a main point)] 1. n. A Rube Goldberg (or Heath
 Robinson) device, whether in hardware or software. 2. n. A clever 
 programming trick intended to solve a particular nasty case in an 
expedient, if not clear, manner. Often used to repair bugs. Often
  involves ad-hockery and verges on being a crock. 3. n. Something
  that works for the wrong reason. 4. vt. To insert a kluge into a
  program. "I've kluged this routine to get around that weird bug, but
  there's probably a better way." 5. [WPI] n. A feature that is
  implemented in a rude manner. 

  Nowadays this term is often encountered in the variant spelling
  `kludge'. Reports from old farts are consistent that `kluge' was the
  original spelling, reported around computers as far back as the
  mid-1950s and, at that time, used exclusively of _hardware_ kluges. In
  1947, the "New York Folklore Quarterly" reported a classic shaggy-dog
  story `Murgatroyd the Kluge Maker' then current in the Armed Forces, in
  which a `kluge' was a complex and puzzling artifact with a trivial
  function. Other sources report that `kluge' was common Navy slang in the
  WWII era for any piece of electronics that worked well on shore but
  consistently failed at sea.

  However, there is reason to believe this slang use may be a decade
  older. Several respondents have connected it to the brand name of a
  device called a "Kluge paper feeder", an adjunct to mechanical printing
  presses. Legend has it that the Kluge feeder was designed before small,
  cheap electric motors and control electronics; it relied on a fiendishly
  complex assortment of cams, belts, and linkages to both power and
  synchronize all its operations from one motive driveshaft. It was
  accordingly temperamental, subject to frequent breakdowns, and
  devilishly difficult to repair -- but oh, so clever! People who tell
  this story also aver that `Kluge' was the name of a design engineer.

  There is in fact a Brandtjen & Kluge Inc., an old family business that
  manufactures printing equipment - interestingly, their name is
  pronounced /kloo'gee/! Henry Brandtjen, president of the firm, told me
  (ESR, 1994) that his company was co-founded by his father and an
  engineer named Kluge /kloo'gee/, who built and co-designed the original
  Kluge automatic feeder in 1919. Mr. Brandtjen claims, however, that this
  was a _simple_ device (with only four cams); he says he has no idea how
  the myth of its complexity took hold. Other correspondents differ with
  Mr. Brandtjen's history of the device and his allegation that it was a
  simple rather than complex one, but agree that the Kluge automatic
  feeder was the most likely source of the folklore.

  TMRC and the MIT hacker culture of the early '60s seems to have
  developed in a milieu that remembered and still used some WWII military
  slang (see also foobar). It seems likely that `kluge' came to MIT via
  alumni of the many military electronics projects that had been located
  in Cambridge (many in MIT's venerable Building 20, in which TMRC is
  also located) during the war.

 The variant `kludge' was apparently popularized by the Datamation
  article mentioned above; it was titled "How to Design a Kludge"
  (February 1962, pp. 30, 31). This spelling was probably imported from
  Great Britain, where kludge has an independent history (though this
  fact was largely unknown to hackers on either side of the Atlantic
  before a mid-1993 debate in the Usenet group alt.folklore.computers over
  the First and Second Edition versions of this entry; everybody used to
  think kludge was just a mutation of kluge). It now appears that the
  British, having forgotten the etymology of their own `kludge' when
  `kluge' crossed the Atlantic, repaid the U.S. by lobbing the `kludge'
  orthography in the other direction and confusing their American cousins'
  spelling!

  The result of this history is a tangle. Many younger U.S. hackers
  pronounce the word as /klooj/ but spell it, incorrectly for its meaning
  and pronunciation, as `kludge'. (Phonetically, consider huge, refuge,
  centrifuge, and deluge as opposed to sludge, judge, budge, and fudge.

  Whatever its failings in other areas, English spelling is perfectly
  consistent about this distinction.) British hackers mostly learned
  /kluhj/ orally, use it in a restricted negative sense and are at least
  consistent. European hackers have mostly learned the word from written
  American sources and tend to pronounce it /kluhj/ but use the wider
  American meaning!

  Some observers consider this mess appropriate in view of the word's
  meaning. 

I hope this further muddies the definitional waters for you :)

Knack Pronunciation Guide: Kludge (as in Fudge)





A SolderSmoke listener (who will remain unnamed) recently corrected me on my pronunciation of an important Knack-related word:  Kludge.   I kludge as in fudge or judge.  He said it should be Kluge as in stooge.  I think we need a ruling her from our etymologist Steve Silverman.   Steve? 

I grew up listening to the 75 meter AM Northeast USA gang.  They said Kludge as in stooge, so I hope we stick with that.  

Wiki has an intereting (and seemingly endless) discussion on this topic: 
http://en.wikipedia.org/wiki/Kludge

Excerpts:


 'An ill-assorted collection of poorly-matching parts, forming a distressing whole' 

"There is a certain, indefinable, masochistic finesse that must go into true Kludge building. The professional can spot it instantly. The amateur may readily presume that "that's the way computers are." 

"The result of this history is a tangle. Many younger U.S. hackers pronounce the word as /klooj/ but spell it, incorrectly for its meaning and pronunciation, as 'kludge'. … British hackers mostly learned /kluhj/ orally, use it in a restricted negative sense and are at least consistent. European hackers have mostly learned the word from written American sources and tend to pronounce it /kluhj/ but use the wider American meaning! Some observers consider this mess appropriate in view of the word's meaning."

Radio's Noble Savage: Jean Shepherd and The Secret People (that's us) -- Shep and Kludge?

I was looking at the pictures from the Nearfest hamfest when I spotted this quite from Shepherd at the bottom of a post in the AM Window by Carl WA1KPD: 

"Okay, gang are you ready to play radio? Are you ready to shuffle off the mortal coil of mediocrity? I am if you are." Shepherd

I Googled the quote and that took me to this 1966 article from Harper's: 

 http://www.keyflux.com/shep/shepharp.htm

The article is a (mostly) accurate view of Shepherd.  Much of it would not be socially acceptable today (and rightly so).  The article correctly describes Shep's stories as being truth-based but also filled with hyperbole.  

This got me wondering:  How did Shep pronounce kludge?  I mean, it could have been him who put me on the pronunciation track of kludge like fudge.  He wasn't being listened to outside of NYC, and maybe Boston and San Francisco.  So that may explain why the rest of the country is getting the pronunciation so completely wrong.  We may be on the verge of a breakthrough here.  Steve Silverman:  ALERT!  

Can anyone find a recording of Shepherd using the word Kludge? A Bronze Figlagee with Oak Leaf Palms will be awarded. 

Check out the Harper's article and the video (above) of Shep talking about THE SECRET PEOPLE.  

EXCELSIOR!

Kludge Controversy Continues


Forget about the sequester!  The real issue facing our country is the proper pronunciation of the word Kludge.   Several visitors to the SolderSmoke table at last weekend's Winterfest weighed in on this issue.   SolderSmoke Lexicographer Steve Silverman wrote to inform me that I had totally misinterpreted his e-mail -- he is in fact rather firmly in the Klooge as in Stooge camp.  I, however, am sticking to Kludge as in Fudge.  It just feels right.  And I may use the awesome power of the SolderSmoke media empire to actually CHANGE the way people pronounce this word.

Check out the California Kilowatt ad.  In retrospect, probably a poor choice of brand name.

"The Soul of a New Machine" -- Re-reading the Classic Book by Tracy Kidder

This book is especially important to the SolderSmoke community because its title has led to one of the most important concepts in our community and our lexicon:  That we put "soul" in our new machines when we build them ourselves, when we make use of parts or circuits given to us by friends, or when we make use of parts (often older parts) in new applications.  All of these things (and more) can be seen as adding "soul" to our new machines.  With this in mind I pulled my copy of Tracy Kidder's book off my shelf and gave it a second read.  Here are my notes: 

--  On reading this book a second time, I found it kind of disappointing.  This time, the protagonist Tom West does not seem like a great person nor a great leader.  He seems to sit in his office, brood a lot, and be quite rude and cold to his subordinate engineers.  Also, the book deals with a lot of the ordinary stupid minutia of organizational life: budgets, inter-office rivalry, office supplies, broken air conditioners. This all seemed interesting when I read this as a youngster.  But having had bosses like West, and having lived through the boring minutia of organizational life, on re-reading the book I didn't find it interesting or uplifting.  

-- The young engineers in the book seem to be easily manipulated by the company:  They are cajoled into "signing up" for a dubious project, and to work long (unpaid) hours on a project that the company could cancel at any moment. They weren't promised stock options or raises;  they were told that their reward might be the opportunity to do it all again. Oh joy.   This may explain why West and Data General decided to hire new engineers straight our of college: only inexperienced youngsters would be foolish enough to do this. At one point someone finds the pay stub of a technician.  The techs got paid overtime (the engineers did not), so the techs were making more money than the engineers (the company hid this fact from the engineers). The young engineer who quit probably made the right move. 

-- The engineers use the word "kludge" a lot.  Kidder picks up this term.  (I'm guessing with the computer-land pronunciation that sounds like stooge.)  They didn't want to build a kludge.  There is one quote from West's office wall that I agree with:  "Not everything worth doing is worth doing well." In other words, don't let the perfect be the enemy of the good.  Sometimes a kludge will do. 

-- Ham radio is mentioned.   One of Wests lead subordinates was a ham as a kid.  Kidder correctly connects this to the man having had a lonely childhood. Heathkit is also mentioned once, sarcastically.  

-- The goal itself seems to be unworthy of all the effort:  They are striving to build a 32 bit computer.  But 32 bit machines were already on the market.  The "New Machine" wasn't really new.  

-- Kidder does an admirable job in describing the innards of the computer, but even as early as the 1978 models,  I see these machines as being beyond human understanding.  The book notes that there is only one engineer on the hardware team who has a grasp of all of the hardware.  The software was probably even more inscrutable. 

-- I found one thing that seemed to be a foreshadowing of the uBITX.  The micro code team on this project maintained a log book of their instructions. They called it the UINSTR.  The Micro Instruction Set.  Kidder or the Microkids should have used a lower-case u.     

-- The troubleshooting stories are interesting.  But imagine the difficulties of putting the de-bugging effort in the hands of new college graduates with very little experience.  I guess you can learn logic design in school, but troubleshooting and de-bugging seem to require real-world experience.  We see this when they find a bug that turns out to be the result of a loose extender card -- a visiting VP jiggled the extender and the bug disappeared.  

-- Kidder provides some insightful comments about engineers. For example: "Engineering is not necessarily a drab, drab world, but you do often sense that engineering teams aspire to a drab uniformity."  I think we often see this in technical writing.  Kidder also talks about the engineer's view of the world:  He sees it as being very "binary," with only right or wrong answers to any technical question.  He says that engineers seem to believe that any disagreement on technical issues can be resolved by simply finding the correct answer.  Once that is found, the previously disagreeing engineers seem to think they should be able to proceed "with no enmity."  Of course, in the real world things are not quite so binary. 

-- This book won the Pulitzer prize, and there is no doubt about Kidder being a truly great writer, but in retrospect I don't think this is his best book.  This may be due to weaknesses and shortcomings of the protagonist. I think that affects the whole book.  In later books Kidder's protagonists are much better people, and the books are much better as a result: for example, Dr. Paul Farmer in Kidder's book  Mountains Beyond Mountains. 

-- Most of us read this book when we were younger.  It is worth looking at again, just to see how much your attitudes change with time. It is important to remember that Tracy Kidder wrote this book when he was young -- I wonder how he would see the Data General project now.

Paddle Output Arduino Keyer Kludge (video)



Ooops -- I got my keyer terminology wrong in this video.   The K1EL keyer just needs a "paddle keyer" input, not an iambic keyer.   One line is brought to ground for dots, another for dashes. (With an iambic keyer, if you make both contacts at the same time you get a string of alternating dots and dashes.)  My homebrew cootie keyer did the job, but I wasn't very proficient, hence the need for this digital kludge. I also got the name of the Arduino guru wrong: he is Massimo Banzi.  Mi dispiace Massimo.

BITX Build Update #14 -- STABILITY!


Good news on the BITX.  I think I have solved the low frequency oscillation problem in the power amplifier.  I tried running the PA off a separate power supply -- the oscillations disappeared leading me to conclude that the feedback was taking place via the power supply lines.   I put a 22 uF cap to ground from the top of the PA's RF choke.  With this cap in place I can dispense with the separate supply kludge. The amp is stable.

This morning I also resolved a different stability problem.  I'm using a relay for T/R switching.  One set of contacts controls the DC power, the other set was supposed to disconnect the receiver input from the antenna/lowpass filter when on receive.  But I had positioned the relay too far from the LP filter and RX input, so I ended up with this long piece of coax that was hanging off the PA output terminal and carrying lots of RF on transmit.  Yes, this led to oscillations.  I thought about repositioning the relay, but I think part of the problem is that even if optimally positioned, the long unshielded contact levers inside this relay would be radiating a lot of RF and causing stability problems.   So instead I put a small reed relay very close to the PA out and RX in connections.  It carries the signal to the receiver when in R mode, and disconnects the RX when in T mode, without any long coax lines or unshielded relay levers.   It works.

I still have a few things to do:
-- I need to build a proper speaker amplifier so that I can dispense with the amplified computer speakers KLUDGE.
-- I need to get a 3 pole double throw switch and some crystal sockets so that I can switch crystals from the front panel.  Three rocks will cover all of 17 meter phone.
-- I have to build a case for this rig.  I'm thinking wood, with tin or aluminum sheeting glued to the inside (for shielding).

Kludge. Rhymes with Fudge. On PBS!

At about 12:26 in this video, David Brooks uses the word "kludge" on the Public Broadcasting System. He pronounces it CORRECTLY!   (But then he and the host question whether it is a real word.)

QRO Problem, and THE KLUGER


Hi Bill,

I've been enjoying your podcasts for a couple of years now and have read both of your books. Please keep up the good work it is much appreciated. In fact, as I can now have both your books and your podcasts on my iPod they are quite literally held close to my heart.

Inspired by your "Kludge Controversy" - enclosed are a couple of photos that I took while on Mount Wellington in Tasmania.


THE POWER OF RADIO

Mount Wellington is a high mountain and is a good launch point for radio waves over the city of Hobart. The visitor lookout has this fantastic warning sign "Electronic disturbances to your vehicle" warning that the transmitter on the mountain can seriously interfere with your car and it may not start, the doors may not open, and the immobiliser may permanently immobilise it. The advice is "A metallic sunshade may reflect radio waves away from the vehicle" and allow you to start it. I'm sure your QRP rigs need no such dire warnings!



WHAT WERE THEY THINKING

And in the very same car park I see this car called a Kluger. In what flavour of English is that a good idea? I know the Brits and Yanks differ over a few phrases but I've never before come across an Oz word that means the exact opposite.

Thanks again for all your many inspiring "broadcasts", and may the Magic Smoke (
http://en.wikipedia.org/wiki/Magic_smoke) always stay where it should!

HP8640B Counter Repair --- Discretion? Or Valor?

 

Inspired by BH1RBG, I cracked open the HP8640B to have a look at the counter circuitry.  Above is the view that greeted me.  That is the main counter board after I pulled it out of its socket.  You can see the seven little red LED display modules.  

It is not as bad as it looks.  In fact, I found the construction and accessibility of the HP8640B to be quite impressive (much better than the Tek 465 with all its flaky plug-in transistors). The manual has good, detailed info on how to get into the various compartments, and even as you work, instructions on which screws to remove or loosen appear on the tops of each RF-tight compartment. Nice. This thing was obviously built with the needs of a future repairman in mind. 


Above is that same board flipped over.  Again, not as bad as it looks. 


Above is board A8A3, the board that I suspect is causing me trouble.  When I go through the troubleshooting routines in the manual, I get to the point where they check decimal point position.  Everything is fine UNTIL I GET TO 16 MHZ.  Then the decimal point is not where it should be and the frequency displayed is very wrong.  (This is in the internal mode -- the counter works fine with an external signal source).  The manual then sends me to Service Sheet 15 which points to possible problems on this A8A3 board, U3, U7 or U6D. 

Troubleshooting this will be tough.  I do not have the extender board that would allow me to test this A8A3 board with the other counter board raised up above it and operating.  BH1RBG noted that getting the extender boards is almost as tough as getting the HP8640B itself. 

While it really bugs me (!) to have  a part of this device not working properly,  I could just leave it as is.  The signal generator is working fine, and I could use the external counter input to check the frequency.  But this is a real kludge. 

What do you folks think?   Fix it or leave well enough alone?  Discretion or valor?  Anyone have an extender board?  Any ideas on where the fault might be?

Travelogue: Cuba DSB and AM. Jose CO6EC and the Islander. We need more info, especially on the solid state Jaguey rig.

Bill’s bench:

Will the High School DC receivers get finished? Future uncertain. But the project was technically interesting. Great working with Dean KK4DAS. Battling AM breakthrough from Radio Marti. We joked that Dean has been listening to Radio Marti so much that even though he doesn’t speak Spanish, he has noticed an increased urge to liberate Havana.

Audio amps: Harder than we thought. Lots of variation in Hfe of 2n3904s. Oscillations.
Not using feedback amps nor LM386s, nor push-pull. Simplicity is a design goal.

Fixing the tuning (bandspread) problem on the VFO was fun.

Antennas? A quarter wave with ground or counterpoise works well. We tried it.

"The Soul of a New Machine"



 
We talk a lot about putting soul in our new machines.  The phrase comes from a book by Tracy Kidder.   Ira Flatow of NPR's Science Friday recently took a new look at this book.  There are TWO recordings in this link.  Both are worth listening to.  The second is an interview with the author, conducted at Google HQ in New York City.  Woz chimes in. 


At about 6:43 in the second interview, Ira Flatow and Tracy Kidder get into a little argument about how to pronounce the word "kludge."  I'm with Ira -- the fact that he pronounces it this way makes me think that we are using a New York, or at least and East Coast pronunciation. 

I am a big fan of Tracy Kidder.  His "Mountains Beyond Mountains"  is about Dr. Paul Farmer, a heroic physician who has dedicated his life to treating the poor people of Haiti.  "My Detachment" is about Kidder's stint as an army officer in Vietnam.   Kidder and his editor wrote a nice book about the crafts of writing and editing: "Good Prose."  "Strength in What Remains" is about the genocide in Burundi.

Arduino Problems -- Back from the Ledge

As I was struggling through this, someone -- who will remain nameless -- told me that because of all the technical problems resulting from the many Arduino IDE "upgrades," suicide prevention hotlines now answer all calls with an automated question:  "If you are calling about an Arduino problem, press 1 for assistance."

It got pretty ugly but with the help of Tom up in NYC I managed to get through it. First he convinced me that it is indeed POSSIBLE to upload the latest version of the IDE -- the dreaded 1.6.7.   I just had to REALLY get rid of earlier versions.  This got me past the horrible Bundled Java Runtime Environment problem (who thinks up these names?).

We then worked with the libraries needed to upload the AD9850 code of Richard AD7C.  You see, I work on Arduino stuff.   Then I stop.  18 months pass.  I forget all I learned.  Then I start over.  The pain begins again.  In an effort to break this cycle, I am now taking notes (in the inside cover of Mario Banzi's book).

I am using the AD9850 with a Kanga Arduino shield designed by Paul M0XPD.   It takes the AD9850 output, divides by 4 and puts it out as 2 square waves in quadrature.  I use this with my R2 phasing receiver.   The problem was that the display on the Arduino showed a freq 4 times the actual tuning freq.  Believe me, this gets old fast.  I considered just getting a San Jian freq counter and supergluing it on the top of the DDS box.  I was going to connect this to the square wave output.  That would have given me one readout with the actual receive freq, and another (on the Arduino) showing the (4X) freq coming out of the AD9850.  But that would have been too much of a Kludge. Tom talked me out of it and modified the code so that the Arduino display shows the actual receive freq.   Thanks Tom.  

Armed with the new IDE and with my knowledge of Arduino basics refreshed, I was able to reload the LA3PNA Si5351 code into my 40 meter DIGI-TIA.  But not before having to swap out the Arduino that drives the Si5351.   One Arduino happily accepted the code, another did not.  Why?  Who knows?  It is a digital mystery.  Those little 1s and 0s are fickle you know.

The Radio Gods rewarded me for all this.  At about 5:45 AM today I was listening to a very friendly SSB roundtable on 160.  The guys were getting ready to sign off.  The last one ended the conversation by asking the others to "Be kind.  Smile at your neighbors."  Nice.
Then WFAX AM started the broadcast day at 6 am, wiping out my 160 meter reception.  Next project:  High-Pass filter at 1.7 MHz.

Arduino Sidecar (instead of a Shield)


In my last post I described my Arduino Keyer Kludge.  In that project I didn't use the standard "shield" board that normally sits atop the Arduino board.  I had used a shield in an earlier project and I didn't really like it.   I prefer to have all the electronics and connections on the top of the board -- this makes for easier experimentation and modification.  

Above you can see my "sidecar" technique.  I build the circuit on a piece of copper clad board using isolation pads superglued to the copper (aka "Manhattan style").   For the Arduino board, I just superglue a piece of balsa wood to the copper clad board, and attach the Arduino board to the balsa with small wood screws.  Electrical connections from the Arduino to the sidecar just go from the Arduino pins to the appropriate points in the sidecar circuit via small-gauge wire.

Herring Aid Motorboating STOPPED!

FIXED!   Following up on suggestions from Tony Fishpool and from Roy Morgan, I put a 10 ohm resistor between the two supply lines and put 100 uF caps to ground at either end of the resistor.   I can now operate the receiver at high AF gain (no problem running a speaker) without the KLUDGE of two power supplies.  The RX sounds great.    I will soon match it up with the equally awesome Tuna Tin 2 for 1976 QRP EXTRAVAGANZA.

Back to the W7ZOI/W7PUA Power Meter

Recent e-mails and Facebook postings from Jim (W8NSA) and Michael (AA1TJ) got me thinking about my old W7ZOI/W7PUA power meter.  The 15 inches (38 centimeters) of snow that fell last night gave me the day off -- and time to play with this very useful and interesting piece of gear. 

The last time I used it I remember thinking that a digital readout would be nice.  But I didn't feel like going back into the world of Arduinos and LCD screens.  So I came up with a real Kludge solution:  I had cheap little DVM that I wasn't using, so I just velcroed it to the side of the power meter.  That little connector above the BNC is the output for a DVM.  I might work on calibration later today.

Wes has some very interesting info follow-up info on the meter on his site: http://w7zoi.net/qststuff.html
I really like the part about how the meter is so sensitive that you can see the thermal noise in the input circuit and can actually measure the strength of signals from your antenna. 

I think I might need a low pass filter at the input of the meter.  There are strong FM broadcast transmitters in this area (some of you may have listened to them in the background of early episode of the SolderSmoke podcast!). I notice that just bringing my fingers close to the input causes the meter and the DVM readout to swing up.  That's not good.
