Field Day with Farhan, his Family and an sBITX Near Hyderabad, India

Farhan and his son Rayyan with an sBITX

The SolderSmoke crew thought it had a tough time this Field Day: Pete N6QW had hoped to do something, but was stymied by hot California weather. Dean KK4DAS had even worse weather. Bill HI7/N2CQR was at a remote QTH with an HW-8 and a wire antenna — he managed just ONE contact (W7RN in Nevada on 15 CW). But none of us had as much trouble as our friend Farhan had. In his account of Field Day in Hyderabad, we see an intrepid ham standing up against the slings and arrows of outrageous fortune that Field Day often throws at true radio amateurs. Here is Farhan’s Field Day story:

—————————–

You asked for it, so here it goes…

I got the chance last evening to head out to our farmland. My daughter Ramsha had her friend were over. By the time we all got into the SUV, it was already 5:30 pm. I had loaded in the Spiderbeam fiberglass pole, the sbitx with LiPo battery and an EFHW ATU strapped on, into the back into my backpack, the toolbox with a few hand tools.

On the way to the farm, rain begin to come down. Rayyan (son, VU3ECQ) started said as much, I turned up the volume on Bruno Mars…

By the time we got to the farm, the rain was over(Ha!). We immediately begin to set up the antenna. I chose an inverted V config for the antenna and to use a tree as the support. The spiderbeam, as any who has been taken in by it knows, is a telescoping 33 feet high mast made of fiberglass. A curious villager decided to help us too. The girls had already taken off to pick the Mulberries.

So, Rayyan, the curious fellow, and I tried to telescope out the mast. The curious fellow, having never read the manual, picked up the mast from the wrong end and all the pieces fall out the other end. (Censored @#$%…). Within 15 minutes, we had all the pieces put back in the order of their thicknesses. I scotchtaped the center of the 66 feet wire to tip of the mast and we all hauled it up vertical. For those who don’t forget maths, you can figure that two section of 66 feet wire will be exactly 33 feet high and when you tie this to the high end of a 33 feet high pole — they just hang down vertically in a straight line. I was trying hard to remember the math teacher’s name when the telescoping mast decided to untelescope into a 5 feet, collapsed height. My son commented that it has worked as advertised. Now, I wanted to remember my son’s Moral Lessons teacher’s name…

Next, we scotch taped the center of the 66 feet wire to approximately 2/3rd height. The curious guy and I walked it up back and took it to the tree. Rather we tried to. The branches kept getting in the way. Finally, managed to get within 4 feet of the trunk and I declared that we could just tie it up with the packing nylon rope bundle we were carrying. We did and it held up.

By now, the two ends of wire had gotten all twisted around each other. We all had an excellent arm workout trying unwind them. The techniques — never mentioned in any antenna handbook — is to hold both ends of the twisted pair in one hand each, spread out your arms and make overhead sweeping motion to flick one wire over the other. This method only adds more twists into the wire. I discovered that wires could be twisted around each other both ways. There is no untwisting them. I discovered this amazing feature!

After watching us for 10 minutes, Humera, my XYL, asked us to forgive the world and bring down the mast and untangle the wires on the ground. By now, a stray cow had also sauntered in on her way back home. I think our language attracted her. She was bellowing for her calf to come and watch.

Next, we, efficiently undid the wire twists. Rayyan and the curious fellow held the two ends away from each other and I raised the mast. Or rather I tried to. At 45 degree tilt, the mast sections add up huge amount of weight. I was tottering around with it when it thankfully leaned onto the tree branches. At this time, I declared it done. We tied the mast at 6 feet height by the rope to the tree trunk. One end went to the a branch of a bush and the other we walked to the point where it was taunt and touched the ground.

I brought out the radio, much to the curious fellow’s surprised, who was looking forward to me doing more entertaining things with the mast rather than a radio. We switched it on, I quickly peaked the ATU to maximum noise and keyed up. The sbitx shut off. Our battery was discharged.

An intrepid ham is never dissuaded by the flings and arrows of time which, when taken at a tide, leads to Field Day. I decided to move the operations to the farm cottage where we had power. But there was no supporting tree nearby. I decided to use the SUV as support.

We packed the SUV at an approximately correct distance from the vernadah of the cottage. We carried the mast over to the SUV and strapped it at two points: on the foot rest and on the overhead luggage rock. At this point the Spiderbeam fiberglass collaspible mast took a commercial break and demonstrated rapid collapse, into the much vaunted 5 feet size. Rayyan was rolling in the grass with mirth. This divided my anger between two opposing directions: toward my progeny and toward my antenna mast. I didn’t move.
I thought like an engineer. The curious fellow and I carried the mast to an illuminated part of the farm, laid it down, and scotch taped each section to the next as the spiderbeam folks had warned us to do. It is strange how memory works better when your blood pressure is up.

The mast went up again, this time strapped to the SUV’s rack, door column, and the footrest. I setup the radio on a table outside the cottage, running the extension cord from inside. The SUV and the antenna were too far for the EFHW to reach the radio.

We asked Humera (XYL) and the girls who were watching us while having their mulberries to DO SOMETHING and not just SIT THERE. So, Humera got inside the SUV and started to roll it towards the cottage. A loud crunching sound announced the sad departure of the sunflower plants we had tied the other end of EFHW from mother Earth. The EFHW had unrooted its support as the SUV pulled it away. These minor inconviences never deter a determine man, remember Gandhiji!

Finally everything was in place, and we fixed up the rig but the microphone wouldn’t key up. So what? I can just operate from the in-built mic and the thoughfully provided on-screen keyboard for CW, right? Well I could but I needed to key CW contiuously to set the SWR. So I opened up the mic. The curious fellow who had carried the radio to the new operating position was new to radio etiquette. He had just picked up the radio and walked, dragging the mic through the slush and weeds. The mic connector had come out.

I took the matters into my hands, by now, Rayyan was trying to show empathy for the old man by making loud noise like Aww! Shucks! and other unmentionables. I cut the cable with teeth, unbraided a small section and wired it up on the connector so I could short it to key the rig. Why can’t the imbecile radio designers think of providing a tune button on the screen??

Finally, everything was in place. I tuned up and AIR net was on. This is the national evening SSB net on 7150. I tried breaking in with SSB a few times but didn’t get through. Finally, I changed to CW and called. The net control asked “the CW station to QSY, this is the AIR net….”. Finally some other SSB station who could copy my CW translated my CW to the net control and we had a three way contact.

At this point the girls declared we had to head home now that I had had my contact.

I was about to let out my public school vocabulary when I heard them say that they were hungry and there was lamb curry at home. The idea of getting back home and drying out, and eating the hot lamb curry and mangoes was too much for me. We folded up. But the mast refused to collapse. The curious fellow who had taken charge of the mast engineering had finally gotten hang of it. With superhuman strength, he had pulled the section of the mast out so tightly that no power on earth could potentially loosen them. I decided to trick the mast into thinking that we wanted it to stay up, so we put it back up vertically and slammed it into the ground. It dutifully woke up and demonstrated the much vaunted ability to fit back into a 5 feet tube.

I looked into the darkness to find the EFHW winder but I couldn’t locate it. The curious fellow had left, scared by the racket the radio was making. The cow and the calf had gone home. We too headed back home.

In the picture, you can see Rayyan standing while I am checking into AIR net. In the background is the SUV with spiderbeam fiber mast that is easy to carry in a 5 feet size.

Some Really Amazing Test Gear

Wow. Really great test gear, and an amazing parts collection. This guy even gets a “nice workshop” comment from Mr. Carlson. Pac1085 seems to be in Rochester N.Y. and he says he specializes in the repair of vintage audio gear. He should have more subscribers. Does anyone have more info on him?

1,280 Antennas at 12 GHz — How Starlink Works

One commenter questioned why we went with the more expensive Starlink system. The simple answer is that it is just better, faster, and more reliable than the alternatives. Many people here are clamoring for this sytem, and they are doing this for a reason. On speed tests I am showing downloads of about 150 Mbps. That is fast. The truth is that my wife is more of an innovator than I am — she was the one who decided on Starlink.

When we were installing this system, I didn’t even know what they meant by “Dishy.” I didn’t know there were motors in the antenna. And I certainly didn’t know about the complicated software and hardware that allow the Dishy antenna to track the Starlink low earth orbit satellites without the use of the motors. The above video explains it all very well.

This is all a great demonstration of what can be done with digital technology, microchips, software and UHF.

Sticker Madness, HI7, April 1

Our friend Lex astutely focused on the date of the release of our report about legal prosecution by the City of San Francisco. The truth is that we made almost all of this up. We did put a sticker on a lamp post at Haight and Ashbury. Dave AA7EE did visit the site and report that the sticker had been removed. But all the rest was made up. We did catch several people in this annual April 1 joke. Unfortunately, not everyone who was taken in was outraged by the city’s supposed action. In fact, we got one e-mail SUPPORTING the prosecution. This fellow said, essentially, that we were getting what we deserved, that we should take this as a life lesson, and stop with the sticker-vandalism. He was serious. Jeez. APRIL FOOL! We will talk more about this in the next podcast.

I know the podcast has been delayed by a lot, but I am still getting things set up here in HI7 land. I hope we will soon be podcasting with particpation from California (N6QW), Northern Virginia (KK4DAS), and the Dominican Republic (HI7/N2CQR).

Happily, my Dominican ham radio license came through — I will be HI7/N2CQR for the next year. At some point I hope to take the Dominican exam and get a real Dominican call.

Lex has been our main point of contact in Europe on sticker distribution (aka VANDALISM!). Lex writes:

Hello all,


Shocked to hear about the “Legal action against Soldersmoke” in podcast :

https://soldersmoke.blogspot.com/2024/04/soldersmoke-podcast-251-aurora-cbla.html

Which could mean a few things :

  1. some official is trying to make a career and he will be very busy because there are a lot of stickers in San Fransisco to remove.
  2. somebody did remove the sticker because they are highly collectable and somebody at soldersmoke HQ saw a opportunity to made one of the best april fools jokes in soldersmoke history pulling the listeners (and readers) leg.
  3. somebody use photoshop and made one of the best april fools jokes in soldersmoke history pulling the listeners (and readers) leg.


Looking at the release date of the soldersmoke podcast 251, IMHO #3 is the most possible with #2 as a good second. When #1 is the real reason, that sucks big time 🙁 (so I’m hoping for the april fools joke outcome)

Let’s continue and get on topic to this e-mails subject.

My XYL and I are just back from a holiday to Berlin and aside of the architecture, visiting a large number of museums and historical exhibitions, there was one place on my personal list I wanted to visit : the “Teufelsberg”.

* The “Teufelsberg” (Devil’s Mountain) is a artificial mountain build with rumble of the ruins of Berlin on top of the “Wehrtechnische Fakultät”, covert soil and plated full with trees. In the early 70’s the location became one of the most important locations for the United States’ National Security Agency (NSA) outside the United States. The facility monitors Soviet and Eastern Bloc communications and gathers important information on the activities of Warsaw Pact countries. 1992 the side got intrest of creative minds and started to get covert by street art.

More info about the history can be found on there website: https://www.teufelsberg-berlin.de/en/history/

Not only the historical part of the site, but also because the XYL and I love street art, we took a day visit it. Aside from the nice walk to it, the excellent view and the great pieces of street art, when you are at a site where street art is present all over the place and even is encouraged (and legal) and you “accidently” just happen to have a few soldersmoke stickers in you bag, you just have to use them. So as of this moment, Soldersmoke is present a the formal National Security Agency (NSA) spy station in Berlin.

I added a few images as a attachment to this e-mail including one to show the great view over Berlin when you on the top deck (only showing one placement, the other 2 are hidden in plane site).

In short : when you can apricate street art and visit Berlin, a visit to the “Teufelsberg” is almost a must. IBEW bonus : there are a few soldersmoke stickers hidden on the top dek for you to find 😉

2014 “Off the Shelf” Regen Comes Off the Shelf (Two Videos)

Walter KA4KXX spotted an error in the schematic of my 2014 “Off the Shelf” regen receiver: The source resistor on the MPF-102 should be 2200 ohms, not 2.7 ohms. See:

https://soldersmoke.blogspot.com/2014/09/schematic-for-off-shelf-regen.html

Walter’s e-mail caused me to take this old receiver off the shelf. In this video you can listen to it in action on the shortwave broadcast bands. In a second video I put it on the 40 meter ham band and listen to some SSB.



Ham Radio in China — Interesting info from 高大伟 David Cowhig

Chinese Radio Licenses and Operating Certificates

David Cowhig (aka WA1LBP, aka Gao Da Wei) was Hambassdor for 73 Magazine on Okinawa when I held a similar “position” on the island of Hispaniola. David is a real Asia hand, and is fluent in both Mandarin and Japanese. He is uiniquely sitated to provide info on ham radio in China. In a recent post he provides this info, and describes how we may soon be hearing from ham Taikonauts in space:

A Really Cool Homebrew Computer

Wow, very cool. On Hack-A-Day this morning:
It caught my eye because the architecture seems similar to that of the MostlyDIYRF PSSST rig.

There is a lot to learn from this little machine, especially for an analog guy like me.

Version II of 15-10 Rig — Updates on Bal Mod, AF amp, and RF Amp, DX

Version II of the 15-10 rig is mostly done. I did a lot of work on the AF amp, balanced modulator, Mic amp, carrier oscillator, and filter. Dean KK4DAS and I continue to test and measure the RF power amplifier. I describe the brutally simple, non-sequenced T/R switching arrangement, and the spread-out open air construction style.

Version I of this rig is on its way to the Dominican Republic. Version II will stay in Virginia. I have already worked a lot of SSB DX with this rig, including, Thailand, Taiwan, China, India, Kenya, Australia, American Samoa, and others.


This video was inspired by the recent work of Nick M0NTV and Charlie ZL2CTM. And of course, Pete Juliano N6QW.

Charlie ZL2CTM’s New Receiver

It is truly a thing of beauty.

I really like that variable capacitor. (Where did that come from? How can I get one?)

Charlie’s calculations on each of the stages is — as always — really nice.

I like the J-310 infinite impedance detector, Charlie’s use of solder wick, the wooden base, and his decision to keep the circuitry visible.

I also like Charlie’s decision NOT to put that VFO in a metal box. Too often we see projects that try to convince us that the receiver just won’t work unless everything is hermetically sealed in submarine-like boxes. Not true! And Charlie’s receiver demonstates this.

Charlie is clearly keeping up the Kiwi tradition of fine homebrewing exemplified by the Tucker Tin 2, ZL2BMI’s DSB rig, and many other FB HB projects from ZL. https://soldersmoke.blogspot.com/search?q=New+Zealand+DSB

Rigs on Vertical Boards — Then and Now

I saw this on Facebook today. G1AVQ (SK) Rig
The G1AVQ rig reminded me of the N3FJZ rig that I worked in 2015:
I am a big fan of breadboards, and have recently been following the lead of Frank Jones W6AJF in using pine boards as the bases for my homebrew rigs. Mine are more horizontal, but we see here from N3FJZ and G1AVQ that a vertical orientation works too.

Band Imaging Rigs (Receivers and Transceivers) — Video from WA7MLH

In the video above (from 16 years ago) we see Jeff Damm, WA7MLH’s band-imaging receiver for 75 and 40 using an IF of 1.750 MHz and a VFO of 5.2 – 5.7 MHz, For a signal at say 3.579 MHz (!) you subtract the signal from the VFO and you end up at the IF. For a signal at say 7.030 MHz you subtract the VFO frequency from incoming signal and get to the IF. (By the Hallas rule you get sideband inversion on 75/80 meters, but Jeff was on CW so this doesn’t really matter.)

Sixteen years ago this receiver was a work in progress and Jeff was having some trouble with the bandpass filters. I had similar trouble with bandpass filters. Like Jeff, I eventually got this sorted.

I was happy to see a comment from my friend Joanthan-san on Jeff’s old video.

Jeff has an awesome and rececntly updated QRZ site: https://www.qrz.com/db/wa7mlh

Band imaging like this is an old idea, and a very good one: I used a slightly different scheme: Start out planning on using a single conversion design. Pick two bands you are interested in. Select an IF midway between the two. Build a single VFO that –when added to the incoming (or the outgoing) signal will get you to one of the bands, and when subtracted from the signal will get you to the other one. Bob is then your uncle. Two bands, with minimal switching.

I got started with band switching with my Mythbuster rig: I would get 75 and 20 meters. The IF was midway between the two at 5.2 MHz. My VFO (from an old Yaesu FT-101) ran around 9 MHz. Boom, it worked, with the added benefit of receiving and transmitting LSB on 75 and USB on 20 with no switching of the BFO/Carrier Oscillator.

Then I did 17 and 12 meters. Kind of a WARC-band special. IF was at 21.4 Mhz. VFO ran around 3.5 MHz. So by adding the incoming modulated signal 18 MHz signal and the VFO, you get to 17 meters. By subtracting the VFO from the incoming 24.9 MHz signal you get to 12 meters. And both are on USB (apply the Hallas rule), so again, no switching of BFO/Carrier frequencies are required.

Finally, at solar max, I built rigs for 15 and 10. Here the IF was 25 MHz. Again the VFO was around 3.5 MHz. Adding the incoming 21 Mhz signal to the VFO gets you to 25 MHz, subtraction of the VFO frequency from the in coming 28 MHz signal takes you to 25 Mhz and thus 10 meters. Again, no sideband inversion (Hallas rule). Both signals are USB and stay on USB. (I built two versions of this rig — one stays in Virginia, the other is heading to the Dominican Republic.)

In the ARRL book QRP Classics, there is an article from the 1990 Handbook entitled “A Band-Imaging CW Receiver for 10 and 18 MHz.” The article may have been based on a receiver built by Dave Newkirk AK7M (Rod Newkirk’s son). Unfortunately in the write-up for the ARRL handbook, the drafters repeat the oft-repeated myth about how 9 MHz IF and a 5.2 MHz VFO would supposedly produce LSB on 75 and USB on 20. This just doesn’t work. But if you put the IF at 5.2 MHz and the VFO at 9 MHz, it does work, as demonstrated by my Mythbuster rig.

A Light-beam QSO in Hollandia, Christmas 1944

This old QST article caught my eye, largely because my father was also in Hollandia on that Christmas day in 1944. He was in the Navy hospital there, recovering from wounds received in the battle of Leyte gulf (in the Philippines). Hollandia, also known at Humbolt Bay, is now Jayapura, Indonesia. The picture above shows the harbor in 1944. Rod Newkirk W9BRD went on to write QST’s inspirtional “How’s DX?” column for many years.

Christmas, 1944


In a wartime world the singular and exclusive camaraderie that exists in the hobby of amateur radio results in so many unexpected and coincidental meetings between good friends, who have previously never seen each other, as to make such happenstance fairly commonplace. But I boast a tale in which time, place and circumstance combined to cause a similar occurrence to be most extraordinary.

The Liberty ship El Segundo Ruiz Belvis lay at anchor in the murky waters of Humbolt Bay, New Guinea, on a tepid tropical night in ’44. In the absence of the moon, the Dipper and the Southern Cross scintillated bewitchingly. On the shore, the lights of the army base of Hollandia burned steadily in contrast to the varipowered signal blinkers which intermittently pieced the opaque darkness throughout the harbor. The latter were visual communication between ships and shore plus an admixture of ship-to-ship chatter, official and otherwise. There was an underlying tense tinge to the atmosphere and the stillness was broken only by the sharp staccato of the Belvis‘ blinker shutters as the signalman transacted port business with the powerful land station.

This was rendezvous. Our Liberty, with scores of army personnel aboard, had here become a unit in the formation of a huge convoy. Crammed into holds, on hatches and into every available nook and cranny of the steel deck, we were Leyte-bound. Stifled, sweaty and hungry on our two meals per day, we wore out deck after deck of pinochle cards and read every available piece of literature over and over again. It was almost a month since we had left Sansapor, scene of our last operation. We were exuberant in the knowledge that we were soon to leave New Guinea.

Christmas was but a few days away and we had had no mail for weeks. Men leaned languidly on the rail and thought of home while others dreamed of the same in their cramped quarters. The circumstances certainly made this Yuletide one to be long remembered. Nevertheless, all that would feature this day for us would be a possible piece of priceless turkey added to the usual dehydrated viands. Just another dragging equatorial day to be piled atop hundreds of others like it.

It was ten o’clock. I was wide awake; only my eyes were tired. Presently, I found myself detachedly reading the blinkers which poked their focused fingers indiscriminately about the bay. My quarters, in the cab of a 399, were on the port rail amidships and afforded a good view across the water. I became absorbed in various bits of chatter between nearby vessels. It struck me that QRM was quite heavy tonight—a sort of an optical 80 meters. I saw one of the lights sign off with a “73.” This was interesting as among the host of merchant marine signalmen, hams are spread pretty thinly. I seized my M-1 torch and focused an insipid beam in the direction of that ship. I sent CQ CQ CQ K. A ham call sign is a cumbersome thing to handle with a blinker. Furthermore, I had no faith in the DX powers of my 3-volt flashlight bulb. I was therefore elated when a bright interrogatory sign beamed forth, aimed obviously in my direction. Contact! True, it was outside the hambands, but band divisions in the microwave region are indefinite anyway.

I was still dubious as to whether my man was an amateur. Rather than complicate matters immediately, at this speed of 8 words per minute, I began in the language of the layman: HELLO PAL WHERE YOU FROM? K. Back in an agreeably rhythmic style came: R TULSA OKLA NAME IS HAL K. The given name and place struck a subconscious inner chord vaguely. Next, I blinked: GE HAL IM ROD FROM CHGO K. There was a pause. He reoriented his beam to compensate for tidal drift and then startled me with: W9BRD DE W5EGA K.

The night quickly took on an exhilarant aspect as we lapsed into ham vernacular, spiced with many Morse slaps on the back. Hal Frank was no other than an old c.w. crony of mine. We had heckled each other on 80, 40 and 20 a countless number of times in the prewar days. In memory I was hearing again that beautiful swing and T9X sledge-hammer signal off his three-element rotary. We discovered mutual ham friends and we exchanged much welcome information and recounted bygone days. He was quite amazed to learn that I was behind a mere GI flashlight (with low batteries at that). The QSO continued far into the night—the next and the next.

We seemed destined to rot in our anchorage. The convoy movement was postponed from day to day. However, this Christmas season took on a much different aspect for me as arrangements were made and, at 0900 Christmas Day, my friend, Wilbur Kuure, W9YNY, and I debarked unsteadily down the ladder and made our way across an undulating swell to the Liberty ship Chittenden. There, we met Lt. Hal Frank, W5EGA, personally, for the first time. We all agreed that it was quite a small and bizarre world that December 25th.

Verbal reminiscences cluttered the air within W5EGA’s exceedingly neat cabin for several hours. Shelves in his quarters were lined with excellent reading material including many late QSTs. Compared to our situation aboard the Belvis, Kuure and I thought this a bit of heaven.

We were thoroughly acquainted by the time we appeared in the officers’ mess. As the cuisine took shape before us and disappeared into our eager gullets, my army pal and I felt somewhat sorry for our less fortunate buddies on the home ship. But such is life. We had, in nautical terms, a “Little Roundhouse,” consisting of a generous helping of everything on the menu. We swept our plates clean to Hal’s amusement. I remember, most distinctly, the dessert of apple pie and ice cream.

Nightfall found Kuure and me “back to earth” on the Belvis after a most delightful Christmas Day. According to plan, we blinked a “goodnight and thank you” to W5EGA through the twilight. That was our last QSO of that series. Not long after that we weighed anchor and headed for our next stop on the long road back home. Our holiday was over, a new year had begun and there was still a war to be won.

— VWS goes Meshtatic. What the heck is Meshtatic?

— Did my receiver sound tinny due to rising frequency response of uBITX Rev 4 amp?

— The Woebot. AI therapy for us!

— Bill BLOWS UP a Tiny SA Ultra. Ooops. But quickly got a new one from R&L Electronics. Veru very useful. I knew 25 MHz IF rigs were inferior, but by how much? How much was the carrier suppressed? Which filters worked better? What was the opposite sideband rejection. TinySA permitted measurement and comparison.

— Is Bill the only one to ever build a 10-15 Dual Bander using a 25 MHz crystal filter. Why? Farhan’s Minima has a 20 MHz 6 pole QER crystal filter. And it too had a rounded passband. But it too WORKED.

— Bill quits 15 meter SSB (for the moment) and goes to the 1.22 nanometer band with a Wilson Clound Chamber.

CuriousMarc Looks at Phase-Locked Loops (PLL)

I really like Marc’s (AL6JV) videos. It is great fun and very educational to watch him and his team troubleshoot some of the old gear they work on. There is also a lot of humor.

In this video Marc delves into the circuitry of the Phase-Locked Loop. I didn’t know that the PLL circuitry has its origins in the space program. NASA needed a circuit that would permit very narrow band reception of a signal that was undergoing the kind of Doppler shift that spacecraft produce. Viola! Enter the PLL. Far beyond Apollo, PLL circuits started to show up in ordinary radio gear. The General Electric (and JC Penny!) CB transceivers that we rescued from 11 meter infamy used PLL as the frequency determining circuit.

Marc gives a really good explanation of how the PLL circuit works. Thanks Marc.

However, Marc gives an incorrect pronuniation of “kludge” (it should sound like fudge). But he is a computer guy and is originally from France, so all is forgiven. He also redeems himself by making fun of the inaccuracies that appear in what he calls “data shites.”
