Paul, I had one of these, back in 1965. I ran a wire, out my bedroom window to my neighbors tree, about 120 feet away. I would load up my 45 record player, with records, and play it into this transmitter for hours, after school. My best friend lived about 5-blocks away, and he would dial it in! Then, one day, it just wouldn’t light up. Stuck it in a box, and mom chucked it, when I was in the USMC. Alas, it was fun while it lasted!

Boy that brings back memories. Built one in the 50s. Had my own radio station in my neighborhood. I'm 73 now. Was talking to one of my neighbors who I hadn't seen for 60 years the other day and she asked me if I remembered being a DJ back then. Amazing this pops up on my internet coincidentally.

My friend built one in1964 and still broadcasts from it ! OMG, I can still remember his license: "Broadcast amplifier 83Y706 meets the FCC restricted radiation requirements under rule 15.204. Wow, how can I remember that?

WOW. I built this unit in about 1959 0r early 60's. We had hours of fun tricking friends with their own car radios into believing the police were coming thru their AM radio's. While sitting out under the apple tree at a table we had hours of fun letting other neighborhood kids hear themselves on AM radio. Thank you Mr Carlson

I had one when I was a teenager! I am 73 now! My twin brother and I hooked up a long wire antenna and tested the range with a portable radio and were able to get 5 blocks in the neighborhood!!!

Another Knight Kit from my youth! I seem to remember "accidentally" connecting one of those up to my 40 metre long-line and...oh, never mind. I also used to drive my mother crazy when she was trying to listen to Arthur Godfrey and I would interject some German polka music from a 78 rpm shellac record. That must have been about 1959.

Yep, That was the “rig” Dad & I built for my youthful local radio station, albeit I added a long wire, which, as I mentioned in a comment on your post about your Gates Broadcast Xmtr, brought an FCC van cruising my neighborhood, in search of my errant unlicensed station. Knightkits & Heathkits put together on the kitchen table were my electronics “schooling” leading up to ham radio, TV repair, Bourns BioMed bench tech, arcade game tech, then EMI/RFI open field lab test tech with the advent of pc & mainframe computer hardware. An even more beautiful pix of your amazingly organized electronic Garden of Eden-out of camera range, of course, is a workbench covered with caps, resistors, half-breadboarded projects buried in a rat’s nest of spaghetti, smeared with rosin drips & burn marks as the smoke of a well used Weller Station wafts over it all...oh, sorry, I was looking at mine! 73’s, WB6U

I built one of these as a kid. I do remember the last part of the instructions where it says to attach the supplied wire to point X and said "this is your antenna DO NOT EXTEND this wire!" Needles to say the first thing I did was attach to my 100 foot longwire shortwave receive antenna and the second thing I did was walk around several blocks around the neighborhood listening for the signal (I ran a tape recorder into it). Went several blocks, and I learned how to couple the little pocket transistor radio to a telephone pole to bring it in.

Never had a Allied Knight kit transmitter of any kind, but I built a Knight stereo and a Knight Span Master. I am now 73 years old. I built the Span Master in 1962 when I was 16. I still have it ! !

Mr Carlson, I am not an engineer nor do I know anything about electronics. I simply enjoy watching your content. You are so intelligent. I learn new words every video. Haha. 43 and still learning and entertained. Thanks

We built a high school "rock radio" station (studio) and fed one of these Knight broadcasters way up in an attic space, near the roof - had about a 1 mile radius in reception. Big dreams back in the 60's !

Mr Carlson is well versed in all aspects of electronics including vacuum tube and solid state. He seems to have that natural ability to troubleshoot with both logic and gut feelings. He's probably one of the best electronic troubleshooters that I have ever seen. Bravo Mr Carlson..I love your videos!

For such a minimalistic bit of kit, I'm impressed. Just look at that signal quality on that thing !!!!! Wow

You're making my life more fun just listening to you!

I was always interested in electronics. Went to college in 1989 initially to get an AS in electronics. Unfortunately i'm not THAT Mathletic and flunked out. Also, the teachers sucked. They were old at the end of their career and just didn't give a crap. They also couldn't teach in a way that showed you application. I went back for Computer aided design and several years later went back again for plastics. But electronics was always dear to me. 35 years after wanting a Ham radio license I studied and tested directly to General a couple weeks ago. The simple electrical theory rekindled my interest in it. Seeing these videos it's the first time in a long time that things make sense. If I had a teacher like you I probably would have hung with it and had a very different career.

I had the Ramsey Am Broadcast TX kit, fun to build and use for my local neighbors, they liked listening to me every evening. Miss the closure of Ramsey Kits!

A tip that I'd like to convey is all the glass tubes have their tube number printed on the side. So if you choose to clean the chassis and dusty tubes it is easy to wipe the tube type off with even a gentle cleaner and a rag. End result a mystery tube. Thank you for making this video and give this old kit some fresh air.

My brother and I had this unit for our radio stations when we were kids (1965-1972). We hooked up the antenna output to a 20 foot piece of 12 gauge wire and went off to see how far it transmitted. We walked about a mile or two; the signal had drifted over onto a major station so we high-tailed it back and turned it off! Great device and great show today!!

This video was a lot of fun! 😃 I'm a former broadcast engineer (age 60) & live in Germany. All if our AM srations were shut down over here in 2015. 😢😣 I always loved my AM rigs & hated working on FM. Bye! 🙋

My very first electronic kit when I was a kid in the 60's! Thank you so much for that nostalgic trip! Brings back a lot of memories!

Great! I built the Graymark broadcaster kit in High School electrical shop in the early 70's. It used a pair of 50C5s and a 12AV6 if I remember.

Enjoy your videos , I am a Ham and have always loved old radios. Until you hear a tube type radio you don’t know what you are missing I grew up with them such a great sound .

Growing up near Chicago was always torn in my locality between Knight kit and Heath kit. My first kit was a Knight VTVM, saved up all summer 1961 between 8th grade and freshman high school.

Had something like this when I was a kid and on a good night it would broadcast 21/2 to 3 blocks ! Good times !

As a kid I built one of these too. Had a lot of fun with it which lead to a career in radio-TV broadcasting where I got to play with the big stuff. ;-)

That is the coolest Vacuum relay I have ever seen.

My dad bought me this very Knight Kit when I was about 12 years old. I put it together, and we broadcast to the neighbors radio and my dad told stories to the 7 year old neighbor boy. What fun it was. You brought back a lot of memories. Thank you. I enjoy your explanations; even if most of it is over my head.

About 30 years ago we were cleaning out my Grandma's house and I found one of these left behind in my uncle's old bedroom he'd used when he was a kid. I guess I was about 13 at the time and it sparked my interest and I eventually got my ham license. Unfortunately when I went to college, I left all my electronics gear at home with my parents. When I got back several years later, this was one of the pieces missing, along with a lot of other gems my mom probably thought was junk filling up my ham shack in the laundry room! Too bad I sure wish I still had it around! It's probably in a landfill somewhere. Thanks for the video. It was really a treat to see this come up in my feed.

When I was a kid, I connected one lead from my phonograph to the metal cap on the top of a tube of an old radio. I first removed the radio wire that normally was connected to the tube and connected the other lead from my phono. This made my old radio into a transmitter. I could then play my phono and pick up the signal on nearby radios. This was a hit or miss transmitter, I didn’t know really what I was creating. I fell in love with radio at an early age thanks to an uncle who also liked radio.

nice find! elegant little circuit there, and at least the person who built it knew his ass from his elbows.

I am loving this. My first kit. At age 10, I used this kit and was an imaginary DJ to my brother and two sisters. This was followed by a Knight Kit 101 experiments kit, Heathkit IM-13, helping my dad build a Heathkit Shawnee Six, trouble shooting a Collins R-388, then majoring in electrical engineering at Texas A&M. Followed by a career in media production and now as I near retirement I do high res audio engineering tracking, mixing and mastering of pipe organ and jazz performances. All starting with that cute little Knight Kit Broadcaster. 😀

When i was 10 years old i built the first piece of electronic gear in my life which was a pair of Knight Kit 3 transistor walkie talkies. I built them with an old Weller soldering gun. They were rated at 100 milliwatts but i doubt they actually made more than 50. Amazingly i learned quite a bit of electronic theory from those kits. They were my introduction to electronics way back in 1961 and sparked my interest in radio. Today i hold an Extra class FCC license and Ive never lost interest in electronics. Thanks for the memory, Paul I look forward to the next excellent video.

Wow...i would have delivered newspapers and mowed lawns for a year to get my hands on one of these as a kid in the 70s

I had 2 of these when I was a a kid in the mid 60's. Drift was a major drift problem. I used the speaker transformer as input and plate modulation.

That device you were holding is a vacuum switch or relay. It is perfect for antenna switching, high voltage switching, or isolating because it has very low capacitive coupling.

We had a Knight kit radio broadcaster amplifier when we were little kids. My Dad ordered it from Allied Radio Corporation in August 1962 when the amplifier in his record player broke down, so he ordered this unit and he and I both built it together. He then plugged his record player in this radio broadcaster and he'd listen to his phonograph records through an AM radio. It was fun!

I still have my Knightkit Broadcaster. I built it around 1961. Three of us in our neighborhood used them to "ham" with. I also used it for a guitar amplifier. And I subsequently got my Ham license....56 years now.

Thanks I wish you were around 57 years ago when I built this unit! My first kit I was 13 yrs old. I would broadcast local bands from my parents garage! This unit had a s surprisingly great ac carrier signal that would travel down a highway some two miles. Thanks for the great video , it’s a wonder I’m still alive at 70 years old now! I didn’t realize that there was a potential of ac on the chassis. Thank you thank you that’s my baby! I went on to be a commercial dj, then onto radio station general manager

What a gem this video is for a person like me who grew up admiring these kits and building a few with my dad. I've loved wires and circuits ever since.

Remember, all real radios glow in the dark.

the Knight kit AM radio I built in 1963 for a project in electronics shop still works fine. there are few good AM stations anymore and the amount of QRM nowadays is insane compared to the good ole days. I also made a radio by drawing the wire on paper with a soft graphite pencil and clipping the leads for the other components such as I could. mixed results but it did work for proof of concept. there were very few printed circuits as they were too difficult to make then esp. for a school shop. my favorite class. I like you video offering and found it very nostalgic. makes me want to pick up the ole butter knight and blow torch and soldier something up. (the soldering irons we were provided were the large plug in type better suited now for soldering up in sheet metal shop. lol so the butter knife analogy is really accurate. Nail and blowtorch was common. keep this stuff up I love it.

I got one for Christmas in 1975 My sister and I would play news caster and weather report I would be in my room and her in her room Mine worked I was 11 Ended up in the Navy Advanced Electronic Went into Aerospace electronics on the LANTRN , Patriot middle project Then into consumer electronics as an audio video bench tech into teaching now back in the field as a remote service tech in Hospitals and Schools communication Made a life time career out of it Thanks mom and dad

Wow! i actuall built this kit, made a console, added two turntables, a tape recorder and a Lafayette Radio mic. It actually worked. Amazing coverage when I “accidentally” hooked it up to my dad’s ham 20meter beam!

Omg, I built one of these when I was 12. 1958? How cool to see it again. I used it to re-transmit my favorite FM jazz station (KRHM) so I could listen to Miles Davis out in the backyard. Man was I a hepcat kid or what? 😂. Thanks so much Mr. Carlson!

Wow did that bring back memories. That was the first transmitter I ever had. I put it in a wooden box and modified it to also be an intercom. I somehow lost the unit over the years but it was the beginnings of my lifelong carrier in TV, Radio and Microwave broadcast RF engineering. Thank you Knight Kit and Mr., C

Dude, you're the living ARRL handbook! Great video and fun teardown!

Great video. As a kid I built a Radio Shack low power AM transmitter and adjusted the tuning up to the TV channels so I could jam the video of our own TV. We had only one TV and if I jammed the channel my sisters wanted then I would get to watch something better on another channel ! Worked great but eventually I got caught. I guess it became obvious finally as after an argument over what channel was going to be watched I would run upstairs and tune the transmitter until I heard screams of displeasure downstairs 😂.

This guy must be the most knowledgeable on youtube.

Ah, this brings back memories of when I fired up my own AM broadcast station as a teen long ago. Via surplus and for about $5, I'd gotten the LF oscillator accessory that was installed in some WWII ART-13s. It was intended to let that Collins-made HF aircraft transmitter tune down the ship frequencies below the AM broadcast band. Since it tuned into the low end of the broadcast band, that gave me an idea. For modulation, I took an audio output transformer that converted from a high impedance (tube) to a speaker (low). I reversed it, feeding the low impedance speaker output of my SW radio into it and feeding the power for the oscillator through the high impedance winding. For an antenna, I hooked up both sides of the coax feeding my 10-meter beam, so that meant about a 20-foot high vertical. Oh, and I hooked a high-voltage capacitor from a TV between the plate of that oscillator and the antenna, so the antenna wouldn't be hot with about 250 volts. Since this wasn't exactly to FCC regulations, I took two precautions. First, I put it on the air on Christmas Day. Surely, I told myself, they won't be working today. And second, for audio I supplied it with what a local AM station was broadcasting. If anyone tuned it in, they'd wonder why that station was on a different frequency. Then I took off in the family car to see how far I was getting. On one direction, a dry, sandy hill top, it petered out after about five blocks. In the other, with damp soil, it was still strong when I got to a wood almost a mile away. That way, it was probably getting about two miles. Here's what I was using: ----- Low Frequency Coverage and More Accessories - The standard ART-13 transmitter frequency range is from 2.0mc to 18.0mc, however many Navy ATC and T-47/ART-13 transmitters and later USAAF T-47A/ART-13A transmitters were equipped with a plug-in Low Frequency Oscillator (LFO) module that allowed the transmitter to operate from 200kc to 600kc or 200kc to 1500kc (at somewhat reduced power, CW only for electrically short antennae.) Early LFOs had a frequency range of 200kc to 1500kc in six ranges designated as O-16/ART-13, while the later LFOs cover 200kc to 600kc in three ranges and is designated as O-17/ART-13A. The LFO modules used a single 1625 tube. When the LFO is in operation the ART-13 Multiplier section is bypassed and the LFO output directly drives the PA. --- The ART-13 was probably the most beautifully made of the WWII transmitters, as you can see from the interior photos here. www.radioblvd.com/art13.htm

When my uncle was still around, we made a small Radio receiver and transmitter. Those were the days, this one brought back memories, which is nice. :) I should get it out of storage, clean it up and see if it still works.

OMG I had this exact transmitter when i was a kid! We got it at a garage sale. I remember the seller saying "oh , oh thats trouble" picking on me for wanting it at 10 years old

I built one of those as my first kit. I used it as an audio amp with a turntable and speaker . It played my mono Beach Boy albums an an acceptable level and sounded good. I replaced it with a Heathkit stereo vacuum tube amp which served me well. Of course I had no idea it was so dangerous, but everything probably was back then. I still have the albums.

This was one of my first electronic projects at age 12. I read about the 12 inch antenna restriction, but it worked so much better attached to the families' steam heating system. We broadcast about 2 miles. Had so much fun. I never figured out why that even worked, because the steam pipes went into the cellar, and hooked to the boiler which had grounded water pipes. Andy

We had a couple of these back in the mid-60s; in fact, I wired one myself. We were required to use an antenna of 10 feet or less. We didn't have any fancy modulation analyzer as shown in this video. Sure wish I did, though! Anyway, we fed our audio not to the XTAL or MAG ports, but from another 8-ohm audio amp which we connected via zip cord to the Knight-Kit's audio transformer terminals. I didn't discover this myself, another genius of a hobbyist put me on to it. It worked great for our neighborhood radio station, for which we had a home-brew console, a couple of turntables, a mike and a reel-to-reel recorder. The Knight-Kit was on the second floor of my friend's house, and the vertically-polarized, fully-extended telescoping auto radio antenna was mounted outside the house. The studio was in the basement of the house, which we were able to do because we ran zip cord from our audio amp to the Knight-Kit's xfmr terminals. "Those were the days, my friend...."

Years ago, I built a Ramsey FM stereo radio transmitter. I didn't know what to expect but the Ramsey transmitter can transmit a high fidelity stereo signal about a half mile with the small antenna that comes with the kit. You could probably transmit a better signal with a better external antenna but I have never tried it.

This episode sure brings back memories! I built many Knight-kits (and Heath-kits) in ages past. I didn't build this particular one, but some of my contemporaries copied the schematic, added an RF amp stage, and began broadcasting AM radio, playing 45 rpm records. The signal carried several miles, but had to be retuned when someone accidentally bumped the counter!

Excellent modulation for such a small device.

This would be a great little kit for people wanting to get an auxilary source onto a nice old radio that did not have any auxilary input. It could give quite extended life to old radios in the new world. Imagine playing some really nice music through that old radio on the shelf from a modern source with this little thing hiding in the back room somewhere.

These were the kind of nerd toys I gravitated towards when I was a kid. Great walk down memory lane.

Mr. Carlson, Dating myself here but, When I was a kid back i'm guessing in the mid 50's or so. Myself and a couple friends used to order stuff from Allied radio all the time. Transistors were I believe about .99 cents each, We built transistor radios with 2 or 3 transistors in them (that was fancy stuff at the time) Anyway one of us bought and built that kit, I believe they called it a wireless oscillator at the time. I lived about 1 mile away from Paul (he's the one that had it). When I left Paul's house I could hear him till I got almost all the way home.

Zback in the 50s we were told to keep your left hand in your back pocket. While working on these. Ac dc radios.

Got mine from allied when i was a kid. my build did not look near as good as that. But it was my first build ever. I learned that caps hold a CHARGE! Did not work first off. It. fell on the floor . I though all was lost. Pluged it in and it Worked ! Thanks for the show. Wish you were around when i was a kid. For some reason i am still alive. Jack Hreha

Wow - I went back to my own little example. Replaced C-7, the 470pf - I had no suitable mono caps, so I used a 470pf silver-mica. It's as stable as the transistor radio I'm using to 'preview' it. It used to drift for about 20 minutes before it warmed up. Thanks!

Your video brought back some good memories. My father was a radio/television repairman from 1925-1968. I'm pretty sure he had the schematics for every radio and television ever manufactured... and then some. I loved playing in his workshop when I was old enough. My first kit was an FM transmitter built on peg board. Making things neat and orderly was mandatory.

I made an AM transmitter for my grade 8 science project, the design was from Howard Sam's "Having fun with Transistors". It used 2 2n107 germanium transistors and I had to wind my own antenna coil. It had a range of 6 feet and appeared on 7 different points on the tuner dial.

Excellent! Feels like I'm watching lost episodes of The Outer Limits circa 1963

Back in the day, Stancor and Triad were the big dogs on the street for transformers and could easily run up to 1/2 the cost of the kits or more, so line voltage design, while "tasty", allowed a fairly affordable build for the hobbyist kid- like I was. My best friend and I would head to the dump about once a month and harvest components from old t.v.'s and radios we dug up for our reuse. Once we took a bucket of tubes to the local supermarket that had one of those courtesy tube testers there, but we were thrown out after about a half- hour of using their electricity and not buying any of their tubes. ☺ Damn, those were fun times for a coupla entrepreneurs!

We have cut the cable cord many years ago. These days I spend my tv time watching RU-vid videos. This is one subscription I look forward to new videos. Not an electronic guy at all I just enjoy his projects. I will leave watching Grays Anatomy and or any other net work gibberish to others to watch. I will pop my popcorn and watch Mr. Carlson’s Lab.

Items such as what you presented here, can be found at Ham radios swap meets. I like to pick up such items as they probably do not work, and see if I can make them work. Some of my favorites are Heathkits of all kind, as these items where all built by someone, and the manuals for them can usually be found on the Internet. I like the simple kits, as they are fun and easy for me to trouble shoot and they maybe useful in my Ham radio. Thanks again for a great job of explaining how all of this "old stuff" works!

I've got some old Allied Electronics catalogs from the late 50s and early 60s I found in my cousins basement. Great stuff to look at and reminisce. My dad had a knight reel to reel tape recorder when he was a teen.

Doesn't matter how many times I see Mr. Carlson's equipment room I am always in awe

Ah, the good old days when Electronic Catalogs came in the mail. Lafayette Radio Electronics, Allied Radio, Radio Shack, Heathkit ! I ordered and built the Lafayette AM Xmtr, back in the day. 73

I love your very clear explanation. I have refurbished that kind of stuff along with jukeboxes since the 80s, and I would have liked to have someone who explained things that clearly when I started to be interested in electronics.

Great job .. haven't seen a Knight Radio Broadcaster And Amplifier since I was a kid. You covered a lot in 45 minutes!

By the way, I believe every video you publish on youtube, Just like you, I am a serviceman technician here in our locality, I restore, repair, and even install electronic equipment as what my clients wants me to do.

Excellent video as usual! And of course EXCELLENT CHANNEL! One of my FAVORITES! This video, and so many others like it are great, but they always assume a fair amount of knowledge and experience from the start. That’s fine and dandy, BUT, let’s face it: WE WERE ALL BEGINNERS AT ONE TIME. I still have a TON to learn myself. That said, SO MANY videos and RU-vidrs like this TALK about safety, but never actually SHOW the safety procedures. Yeah, yeah, I know: If you don’t have experience working with this stuff, you shouldn’t be doing it. But let’s face it: Nine out of ten REALLY GOOD technicians on RU-vid, AND IN THE REAL WORLD, are SELF TAUGHT. I took correspondence courses from the Cleveland Institute of Electronics 30 years ago, but it was all theory, almost no hands on, and we all know that the learning doesn’t RRREALLY start until we roll up our sleeves and STICK OUR HANDS INSIDE. These self-taught, now-EXPERTS, are people that INDEED stuck their hands in places and at times they shouldn’t have. How about making some videos, or just appending an extra five minutes to future videos ACTUALLY SHOWING THE DISCHARGING PROCESS; actually SHOWING the do’s and don’ts of SAFETY. MOST RU-vid channels like this show scene cuts AFTER something has ALREADY been done (this channel included): New scene: “Ok, now you can see that I have replaced all the caps.”.... NNNNO!!! SHOW yourself replacing the caps! SHOW yourself discharging the unit before sticking your hands in there. SHOW yourself taking measurements, and SHOW beginners that lethal voltages REALLY ARE present BEFORE any discharging takes place. If you do this, you will foster a LOT more education, and especially, A LOT MORE SAFETY. In short, show, SHOW, SSSHHHOOOWWW! ... Or just like the song by Canadian band, Rush, says, “SHOW ME, DON’T TELL ME!”... Great video, great channel, and I am a faithful viewer, follower, and fan, but SHOW rather than just tell! Thanks!

Another great learning experience, I had one of these Knight Kit broadcasters when I was much younger, really brought back some great memories!

Lafayette Radio made these AM broadcasters also--and in fully built form. They continuously but slowly would drift off frequency--even after being on for 5 or 6 hours--requiring listeners to retune every 15 minutes or so. But for $5, the broadcasters still were a good deal and lots of fun.

Great video! A few years ago I bought and restored several battery tube portables and then discovered that there was nothing worth listening to on the AM band......so I got a two tube AM transmitter kit and connected it to my Seeburg BMS1000 and now I can enjoy the radios 😁

Oh did this bring back memories. I built one of these back around 56 or 57. Didn't work that great but it was a lot of fun...

I built one in my youth (early 1960's) and used it to jam the local radio frequency of my sister's favorite radio station. What a blast.

I can remember one Christmas about 1950 when my older brothers had this device. They imitated the "HADACOL" adverstisment. The All american 5 were also called an AC/DC radios. People in the rural area with no ac could but batteries to add up to 120 Volts and have a radio.

A Lafayette LA-23, of the same vintage, gave me hours of fun which culminated into a 60 year career in radio broadcasting.

Wow - I remember every detail from age 9 when it was a brand new kit; I wish I had kept it. ( I built TWO of them! Worked, but I never could get the range to go beyond a few houses. RF was a complete mystery to me as I experimented with various antenna "wires" and overworked that slot on the tuning capacitor. Unsupervised 110 VAC construction by a kid... good old days! lol)

Very entertaining always informative. Thanks Mr. Carlson

I built a KnightKit Phono Oscillator in 1964 and actually Increased Output and made it Crystal Controlled, 1600 KC. I lived in Benton, AR. on a Large Lot, on River Street, and never got a complaint. It was a simple kit with excellent Schemetic and Pictoral Diagram. I was 14 Years old.

Nice review of this transmitter. I saved one of these from the trash. It is the earliest model of Knight kit broadcaster that did not have a bottom cover. They must have felt that who ever built it would keep their fingers out of it. After a few years they did come out with the model you have.

Knight kit had some pretty cool products. When I was 5 years old my father built a C 27. It was a unique two channel CB. It had a VFO so you could listen to all the channels you didn't have. His callsign began with the number 5. The ITU put the kibosh on that so the FCC switch to the letter K as a prefix.

Thx Mr. Carlson ! Your explanations are both clear and concise and entertaining often ! I wish I had decided to become an instructor years ago as I think I would have followed your lead. My instructors were quite dry most of the time and thus quelled most of my original desire to learn electronics as originally intended. I look forward to following your coursework. The materials of CREI were my original material obtained and it was quite good. They were sold to another company and quickly went downhill , dang shame as many followed them at the time.

I took my 1961 Knight Kit Broadcaster mobile one time. Using one of my friend's dad's shaver inverter, plugged into the cigarette lighter of the ole 1949 Chevy, and the car radio antenna disconnected and hooked to the Broadcaster. My friend could hear me about a mile away, as I remember (a relatively open area). Bet that little inverter was huffing and puffing and I can't remember if it survived the test.

At 40:00 did anyone else think of the "Outer Limits" theme? "There is nothing wrong with your television, do not attempt to adjust the picture............" Another great video Mr C. Wish I knew a small percent of what you do!

Oh man, am I glad I watched this one! Very glad you pulled out the schematic and went over it with us. I've mentioned before that I have a guitar amplifier project I messed up in my youth. A decade or more later and it is time to finally get around to correcting it.

I built one of these about 1965 and have a lot of good memories. I think the cost was about $10.

Paul, I've watched this video a couple times now and this time the came to me, " Why doesn't Mr. Carlson build a AM broadcaster like this ... only better" and post it to Patreon!

I’m fascinated by this. I’ve yet to comprehend your terminology, so I’m going to your first videos so I can learn from the very beginning. This is just technical enough to intrigue me, plus I won’t be getting my hands dirty. Thanks for this.

Especially true with antiques: If it's not broken, don't fix it.

Always enjoy you bringing out an older piece of american electronics. Things we can definitely still learn from. Thanks Mr Carlson!

I had a similar "home radio station" in the early '60s (though not built from a kit). It was called the Caravelle, made by Remco. The plastic case of the unit was mostly empty. The microphone, you could only talk into it while holding down the button on the back of it. I gave my station the unofficial call letters WDSC and would play records through it as a DJ.

Your videos are absolutely wonderful, wish I had you as an instructor when in was in tech schools back in the mid 70’s. Thank you again, 73 wd4dda
