Wonderful, Imre - thanks for sharing! This brings back memories; the notebook from my early teens looked much the same. To anybody watching, who also chronicled their hobby with a journal: please don't be tempted to discard it - find somebody to pass it on to, even if it may be years before they recognise its value. Not everything is recorded and findable, even on the Internet, and ideas don't become obsolete just because the technology they were first implemented with is replaced. After a 40-year electronics career I refer more, not less, to original papers and articles, many from a century ago. Engineering's an applied science, so it exists in a historical context. We understand it better when we get the chance to see where modern technology fits on the timeline and how it arrived there.
lovely, it brought back so many memories of my childhood and my hand-drawn electronic circuits, all gone now. Your drawings were so beautiful to look at as well. Also the radio station calls signs brought back so many memories too.
The radio calss signs are in my collection but I collected it from other youtube video, many years ago. i found it nice, intersting and some stations I listened on my receivers.
Thanks for sharing this. Your notebooks are a delight to the eyes of this fellow radio lover. I still sketch out schematics and keep notebooks of my radio projects, but I don't share your fine eye and hand. The SW station idents from the Cold War era were the perfect audio too. It brought back memories of a wonderful time for radio hobbyists long gone. 73 de AB1DQ / James in CT USA.
Thank you for your kind note. I am still enjoying the radio hobby-check out my latest video. I have never obtained a HAM permit because I am only a listener and do not transmit at all.
I am in Illinois, USA, but I am originally from Hungary, Europe. My notebook is from there. I recently retrieved it after 30 years of storage at relatives. I was so happy to get it back, and I was able to create this slideshow and share it with a few thousand viewers.
Old school, how wonderful to have kept such a treasure it reminds me when I showed my younger cousin how to make a Crystal set. He said to me many years later just before his demise that it was that Crystal radio which led him to his work which I found out later was rather hush hush satellite receivers. There is a certain magic hearing static and a voice from a little wire and a detector. 73 de G8WOF / Wirral UK nnnn
very nice. Thanks for posting. The schematic at 1:41, this I have built around 1967. The transistor was OC612 and the diode an OA85(?) . The power giving part tuned to a local MW station with a large outdoor antenna. The receiving part on SW. Good old times.
Как приятно снова услышать старые позывные стран мира . Эти позывные знакомы мне с далёкого детства . Спасибо Вам огромное . С наступающим Новым годом ! Желаю мира , здоровья и процветания . 73 !
Merci pour le partage des documents de votre ancien cahier et des ritournelles des anciennes stations radio onde courtes. Thank's for sharing the documents of your old notebook and the jingles of old short waves radio stations - (broadcasts). Happy New Year 2024 and 73' from FRANCE.
Happy New Year to France! I have always been and will always be just a shortwave listener, amateur radio enthusiast, and shortwave broadcasts listener.
I have a similar notebook from when I was starting out in Electronics, in the early 70s. It has lots of simple radio and test equipment circuits that I copied out of book in my school library and different hobby magazines.
Thanks for posting.... I really enjoyed hearing (again) the unique tuning signals and announcements at the start of short wave broadcasts. I spent a few thousand hours of short wave listening from age 11 to my middle 20s.
Nice memorires. I started building radios in 1963, from crystal detectors to tubes. I have a notebook too, very similar to yours, with many interesting projects either intended or made to finish in that time. It was a very innovative period in my life.
I have never ceased to be innovative up to this day! I am still using and developing crystal diode radios. For many years now, I have been using an overnight AM band crystal radio without an external antenna to listen to news and sports channels. It operates without a battery or external wires-just the radio with a tuning knob and a 3-foot long wire for a piezo buzzer-based earphone. You can find these crystal radios on my channel. Please search for it
@@imreolajossr6355 I used such a receiver after trials in 1964. The earphones were of crystal type and I used an adjustable Lead suplhide crystal. Just a piece of antenna and some simple groundingand the local AM station came in strong,
I wish I also had kept such a logbook of my crazy ideas. Your carefully kept notebook is a treasure trove of simple yet useful diagrams. Thank you for the wonderful collection of familiar radio jingles.
@@imreolajossr6355 OMG, what good luck! I think you deserved it. Never before have I seen such a great collection of schematics drawn by hand. IMHO schematics are not only technical documents. Some are pieces of art. In my twenties I copied the schematic of a tube amplifier featuring a ELL 800. I did it in black INK to hang on the wall and was mighty proud of it. When listening to one of my many vintage audio sets I often study the pertaining schematic and rejoice over their inventors´ ingenuity.

Üdv; Köszönet ! (1:00 kristálydiódás vevő (wc -papírhengerre tekercselve + germániumkristály+tű...), az első rádióm tökéletesen működött a 70-es években !!!
Én még mindig készítek ilyen rádiókat. Úgy látszik, így maradtam. Fejlettebb kivitelben természetesen, de az alapelv ugyanaz. Nézd meg a kristálydiódás készülékeim videóit is! Azokat ma is használom. Nem kell hozzá semmi, csak egy doboz a hangoló gombbal és a fülhallgató. Az elem soha nem fogy ki, mert nincs benne. Kikapcsolója nincs, mert mindig be van kapcsolva. Éjszaka híreket hallgatni egy csendes szobában, kiváló!
Természetesen évekig fejlesztettem, hogy ne kelljen hozzá külső drótantenna. Az is kellett, hogy olyan helyen lakjunk, ahol nagy teljesítményű adók vannak pár kilométeres körzetben.

You still keep it? Nice, I tossed mine long time ago, otherwise it looked mostly as yours. I had also many schematics for tubes. So certainly you are more advanced person.
These are just circuit diagrams and ideas, no PTH. In most cases, I worked on circuits by assembling components on the surface of copper spots. Yes, it's almost like surface-mount technology I invented because I hated drilling holes for the components. My co-workers were not happy with that. They said, 'The components will fall off over time.' But that never happened.
Też takie zeszyciki miałem !

Było pięknie !!!!
I wish more people (countries) would still be interested in broadcasting (radio is magical, but less and less people see that) The hardest thing about being the listener only is that some day we will have nothing to listen to PS: I tried building the first one from the schematic and the onlything I was able to listen to on it was my noisy plasma television :( (I mean it does work, but I would like to listen to music not noise) I did get outside at night but its realy hard to find a lonly place where u can put 30m of wire above ground Will try again, I just hope that there will be something strong and close to listen to Because right now the closest thing (still standing) is 15kW station about 150km away, which is just to weak to drive the radio I do have Kossouth from Solt which is about 700km away, but I guess 2MW station is still to far away and to weak
There is always something to listen to on a good wideband receiver. I am using Yaesu VR-500 and ICOM IC-R20 wideband receivers. During the day, I can tune in to the air band, ambulance (911 emergency) calls, police communications from 30 miles away, HAM operators on higher bands (28 MHz), and the CB band. The FM band, AM broadcast band, and shortwave broadcasts from 9 MHz to 18 MHz are also good to listen to, even during the daytime-at least in my location.
@@imreolajossr6355 well, thats true We still have FM band (for now, but even that will be taken away in favour of DAB) Sadly in Europe emergency services are using tetra and are encrypted As for listening to HAMs, meh, I never listened to anything interesting there yet I like broadcast radio because of all the music and culture (and to get this u use an universal interface, u dont need to know hungarian to find the website and their webstream, you only go to 540khz and done) There is something magical about analog radio, when the station that is 1000km away gets to u and its signal reflects that since its not strong Not even sure how to show this magic to younger generations, cuz if we dont, then they will destroy it PS: u still have SW bands, I thought FCC took that away to sell to stock brokers to use to transfer stok data there
I'm delighted that you like it. I spent a long time drawing these pages, and I was thrilled to have it back after 30 years of storage at a relative's place!
Nice notes, thanks for sharing Imre ! I started ten years later than you, with similar projects (LW and SW receivers, LW transmitters, VHF receiver, oscillators .. all using tubes and Ge transistors). Schematics were nearly the same, only newer series of Ge transistors (MP43, TG50, TG5.. instead of OC series ) were used. But my notes are not such accurate as yours ;) 73, Marek SP2MKT
I have learned a lot by drawing these diagrams. Library books were not available for longer time but these notes were on my desk all the time.@@chuckermatinger3794
1950's fashion of drawing PNP transistors upside down, technically not wrong, but definitely cute. 🙂 However at 1:16 your battery symbol is wrong, the only actual mistake I spotted from a quick scan through
I'm glad you have the chance to look over my electronics notes. I spent a long time creating this slideshow of the pages. The battery polarity is clearly marked on slide 1:16. Unfortunately, I can't remember the source of that circuit after 62 years.
@imreolajossr6355 yes the battery polaity makings + and - are correct, But the battery symbol is drawn backwards, the larger plates are + so it should be; + lili -
By the way, these are hand drawings made with an ink pen. I was careful not to drop any ink on the paper. On that specific page, the battery polarity is correct; on all others, it's either wrong or mixed up. However, the + and - signs are correct on all circuits. I do have the original notebook on the bookshelf in front of me, but I’m not going to fix it
@@wizrom3046 I've always used the opposite method in my personal notes. It made sense to me because I consider the body of the dry cell as negative and the tip as positive. This has been my own standard since the 1960s. But, as you can see, it hasn’t always been like that…
@@imreolajossr6355 of course it is your right to draw the symbol any way you prefer. 🙂 But I did notice on other pages you drew the battery symbol as correct (ie; matching all the international standards) but on that one page was reversed. I'm an old timer too, and have done electronics since 1975. I thank you for sharing your notebook, it is a little piece of history, and I hope I have not caused negativity here by pointing out that one detail. Thanks for sharing! 👍
The forst transistors were pint-contact transistors. It was easier to meke thereforetransistor was PNP that time. See more info on the web or here: spectrum.ieee.org/transistor-history#:~:text=The%20point-contact%20transistor%20was%20built%20around%20a%20thumb-size,charges.%20These%20positive%20charges%20are%20known%20as%20holes.
The schematics are marvelous remind me when I started the electronic hobby reading a book from the fifties Audels Radiomans Guide. It would be great if you made a video of the circuits and constructions.
Hey, back then there were no video recorders or phones, only film cameras for making movies. Nowadays, those parts are inaccessible, lost to history. You might occasionally come across some old transistors, but not the ones depicted in the diagrams. Enjoy what you see and hear in this video. At least the sound matches the era of my drawings. I'd love to see a similar notebook from someone on RUclips in this slideshow format. Hurry up, the paper material in your notebook is aging, turning yellow, just like we do as we get older..
@@tr_2sc1970I'm sorry, but I don't have any of those transistors or any other parts for those circuits. These days, I prefer to work on larger transistor radios. They keep me busy day by day. I am retired.
Looks just as my notes from around the years 2000-2003. I can even recognise some of the diagrams. They probably were copied from the same source by authors of the books we used, 40 years apart and in different countries. Except for the 0:46 - I don't remember anything mentioning BF245 in these books.
Only problem is , this page will disappear when I go somewhere else . I hope I can call it up again later . But this device looses everything if I don’t at least touch it every 15 seconds .

I am not selling the original but a laser copy of this notebook. At the same time, when I received this notebook back, I also got my mainframe computer notebooks - four larger (A4 format) bonded volumes and the everyday used program cards. The oldest computer notebook dates back to around 1969 and is about a transistorized French computer. That is a treasure for me too.
Thanks for your note. These are only copies of official papers and books. I am aware of a few issues you mentioned, but some of them stem from the original parameters of the parts. At the time I made these copies, I didn’t have the knowledge to address the problems. I was just happy to obtain any material related to the subject.

I did get outside at night but its realy hard to find a lonly place where u can put 30m of wire above ground
Will try again, I just hope that there will be something strong and close to listen to
Because right now the closest thing (still standing) is 15kW station about 150km away, which is just to weak to drive the radio
I do have Kossouth from Solt which is about 700km away, but I guess 2MW station is still to far away and to weak
There is always something to listen to on a good wideband receiver. I am using Yaesu VR-500 and ICOM IC-R20 wideband receivers. During the day, I can tune in to the air band, ambulance (911 emergency) calls, police communications from 30 miles away, HAM operators on higher bands (28 MHz), and the CB band. The FM band, AM broadcast band, and shortwave broadcasts from 9 MHz to 18 MHz are also good to listen to, even during the daytime-at least in my location.
@@imreolajossr6355 well, thats true
We still have FM band (for now, but even that will be taken away in favour of DAB)
Sadly in Europe emergency services are using tetra and are encrypted
As for listening to HAMs, meh, I never listened to anything interesting there yet
I like broadcast radio because of all the music and culture (and to get this u use an universal interface, u dont need to know hungarian to find the website and their webstream, you only go to 540khz and done)
There is something magical about analog radio, when the station that is 1000km away gets to u and its signal reflects that since its not strong
Not even sure how to show this magic to younger generations, cuz if we dont, then they will destroy it
PS: u still have SW bands, I thought FCC took that away to sell to stock brokers to use to transfer stok data there
شكرآ جزيلا على هذا الفيديو المفيد . تحياتي لك من تركيا. اتمنى ان تعمل جميع الفديوات باللغة الانكليزية.
See my other video where I inserted Englihs notes on the blank pages!
Great, really. In niches a Feeling of a careless childhood
Exceptionally well done! So much information in such a short video. Bravo. 73 OM
I'm delighted that you like it. I spent a long time drawing these pages, and I was thrilled to have it back after 30 years of storage at a relative's place!
Everyone who was interested in electronics had such a notebook
Nice notes, thanks for sharing Imre ! I started ten years later than you, with similar projects (LW and SW receivers, LW transmitters, VHF receiver, oscillators .. all using tubes and Ge transistors). Schematics were nearly the same, only newer series of Ge transistors (MP43, TG50, TG5.. instead of OC series ) were used. But my notes are not such accurate as yours ;) 73, Marek SP2MKT

Excellent 👌👍
Reminds me of my college day! Wow!😊
These are beautiful diagrams! You did these?
I drew it by hand with a dip pen featuring a steel nib. I tested several circuits with it and even used it for a longer period.
@@imreolajossr6355 Each diagram is a perfect example of technological art!
I have learned a lot by drawing these diagrams. Library books were not available for longer time but these notes were on my desk all the time.@@chuckermatinger3794
Please leave this video up for all time. I need a few years to study it. LOL!@@imreolajossr6355
It reminds me so many things, thanks !
I remember when pF was called mmF, I'm that old. Kilo Hertz was also Kilo Cycles.
Very nice. Thanks from Argentina ❤❤
Interesting 😊❤

Excelent job,thanks a lot my friend!
Greetings from Buenos Aires
Fun to see occasional П403 in your schematics. I wonder if it was considered a decent transistor in Hungary at the time?
Yes, It was only or almost only the high frequency transistor that time.
1950's fashion of drawing PNP transistors upside down, technically not wrong, but definitely cute. 🙂
However at 1:16 your battery symbol is wrong, the only actual mistake I spotted from a quick scan through
I'm glad you have the chance to look over my electronics notes. I spent a long time creating this slideshow of the pages. The battery polarity is clearly marked on slide 1:16. Unfortunately, I can't remember the source of that circuit after 62 years.
@imreolajossr6355 yes the battery polaity makings + and - are correct,
But the battery symbol is drawn backwards, the larger plates are + so it should be;
+ lili -
By the way, these are hand drawings made with an ink pen. I was careful not to drop any ink on the paper. On that specific page, the battery polarity is correct; on all others, it's either wrong or mixed up. However, the + and - signs are correct on all circuits. I do have the original notebook on the bookshelf in front of me, but I’m not going to fix it
@@wizrom3046 I've always used the opposite method in my personal notes. It made sense to me because I consider the body of the dry cell as negative and the tip as positive. This has been my own standard since the 1960s. But, as you can see, it hasn’t always been like that…
@@imreolajossr6355 of course it is your right to draw the symbol any way you prefer. 🙂
But I did notice on other pages you drew the battery symbol as correct (ie; matching all the international standards) but on that one page was reversed.
I'm an old timer too, and have done electronics since 1975. I thank you for sharing your notebook, it is a little piece of history, and I hope I have not caused negativity here by pointing out that one detail. Thanks for sharing! 👍
Love it! You had a lot of PNP's that time. Why no NPN's ?
The forst transistors were pint-contact transistors. It was easier to meke thereforetransistor was PNP that time.
See more info on the web or here: spectrum.ieee.org/transistor-history#:~:text=The%20point-contact%20transistor%20was%20built%20around%20a%20thumb-size,charges.%20These%20positive%20charges%20are%20known%20as%20holes.
The schematics are marvelous remind me when I started the electronic hobby reading a book from the fifties Audels Radiomans Guide. It would be great if you made a video of the circuits and constructions.
Hey, back then there were no video recorders or phones, only film cameras for making movies. Nowadays, those parts are inaccessible, lost to history. You might occasionally come across some old transistors, but not the ones depicted in the diagrams. Enjoy what you see and hear in this video. At least the sound matches the era of my drawings. I'd love to see a similar notebook from someone on RUclips in this slideshow format. Hurry up, the paper material in your notebook is aging, turning yellow, just like we do as we get older..
@@imreolajossr6355 Excuse me I thought you still have some circuits with the same parts!
@@tr_2sc1970I'm sorry, but I don't have any of those transistors or any other parts for those circuits. These days, I prefer to work on larger transistor radios. They keep me busy day by day. I am retired.
@@imreolajossr6355 👍
Very good reception on medium wave.
I didn't know that there was still a Polish channel on 1030kHz. When was the test carried out?
Very nice!
Looks just as my notes from around the years 2000-2003. I can even recognise some of the diagrams. They probably were copied from the same source by authors of the books we used, 40 years apart and in different countries. Except for the 0:46 - I don't remember anything mentioning BF245 in these books.
Sir,
Have circuit diagram of germanium transistor radio with AF 116 ?
I am sorry not at all.
Thank you for sharing your impeccable work! Love those days gone by...de KD3EZ
very good
Nagyon szép kapcsolási rajzok, amiknek zömét nem is ismertem.

Thanks for sharing. My note book is not very legible.
👍👍👍
I can't do it, but it reminds me a lot of my school years...
Good
I wanted to get some recipes and this device closed out before I was finished copying .
Only problem is , this page will disappear when I go somewhere else . I hope I can call it up again later . But this device looses everything if I don’t at least touch it every 15 seconds .
This better be good
❤
How old are the sound recordings ?
The sound recording is not my own; it is part of my collection. I believe it is contemporary to the notebook.
A bygone era😢

You´re selling it on ebay? Please keep the original for yourself. You drew it and it belongs to you.
I am not selling the original but a laser copy of this notebook. At the same time, when I received this notebook back, I also got my mainframe computer notebooks - four larger (A4 format) bonded volumes and the everyday used program cards. The oldest computer notebook dates back to around 1969 and is about a transistorized French computer. That is a treasure for me too.
i would have been in kindergarten/ first grade elemantry school
Most of schematics have mistakes. That is not good.
Thanks for your note. These are only copies of official papers and books. I am aware of a few issues you mentioned, but some of them stem from the original parameters of the parts. At the time I made these copies, I didn’t have the knowledge to address the problems. I was just happy to obtain any material related to the subject.

I am glad for you to know. OK.
Sok olyan séma van,amelyben tervezési hibák vannak.Nem csoda,hogy hova jutott a rádióamatőrök fejlettsége
Tervezési hibák ma is előfordulnak. Példaul a telefonjaink folyamatosan frissítéseket kérnek.
A technika története során mindig az volt a cél, hogy kiküszöböljük a hibákat és jobb minőségű termékeket hozzunk létre. Néhány kapcsolási rajz a valóságban más módon viselkedik, mint amire az ember számítana. Valamelyik kapcsolási rajz nehezen érthető, mert az elvi rajzon nem látszik a gyakorlati megvalósítása, az alkatrészek elhelyezése.
