In 1967 when my family went to the Worlds Fair in Montreal, we went thru the USSR exhibit. They had a display of Soviet color TVs. As a precotious teenager I went behind and peered thru the back and saw Japanese components...before the docent shooed me away.
s for this TV, it was a Rubin (Рубин)401, a Soviet design but based on French technology bought with a license for SECAM. It was modeled on a Thomson tv called Arlequin. In the early series, American RCA cathode ray tubes were bought for them before the Russians rolled out their production. They planned to buy licenses from RCA for IL CRTs in the late 1970s and put up a factory. But they ran out of money. They took their cue from the Poles who bought and built a color CRT factory near Warsaw with RCA in 1976-79. Unitra produced them with modifications until 1990. For communism they were not too bad.
There was more of that. Poles bought licenses for tape recorders from Thomson and Grundig. Radios after the war from AGA. Speakers from Pioneer. Scalers were partly made thanks to SESCOSEM then SGS Thomson today STMicroelectronic. Electronics for color tvs those with RCA cathode ray tubes were also based on Thomson. Headphones had licenses from Senheiser (did not go into production)VCRs were built based on Ampex, Philips, JVC, Matsushita, Siemens and grundig technology but then Daewoo and earlier Bondstec made them. Russians assembled officially it was a license of VCRs Panasoniki NV 7000 as Elektronika BMK 12 then Samsung VK 8220, before that they peeped Philips. this one had a co-op with Tesla in the 80s in Czechoslovakia VCRs, partly ICs. Romanian factory Uzinele Electronica bought black and white TV licenses from Matsushita in the 1960s. Hungary's Orion collaborated with Thomson and Matsushita assembled NV 366 VCRs. Best regards.
@@janmos5178 In Rubin and other ULPCT type soviet delta CRT was used. It was bad copy of some old RCA CRT model and it was very unreliable.

This group is one of the famous radios belonging to the Iraq Electronics Company, and its famous name is Al-Qaythara, according to the ancient civilization of Iraq. It is considered one of its most proud products in the 1980s. It was distinguished by its high quality of reception for radio stations and the external reception. It was easy to maintain and had a modern electronic plan in terms of components. It is characterized by the use of a Philips BC108 type transistor with three intermediate frequency stages..BF179 signal amplifier with one superheterodyne stage..BC160 with two stages of the amplifier. This is a push-pull type for a small pocket radio. It uses two batteries, the size of a pen. 3V voltage draw...single wave AM system.
After your Soviet AM radio video with the Olympic 402 i picked one up off ebay. That radio works amazing. The one i got actually worked perfect with no issues and picks up stations my $300 radio had troubles receiving. Thanks shango for showing us these cool radios
those transistor radio so cool and vintage. i love all of the videos you make Thay are so good . i watch your videos a lot and you get so much cool stuff.
THE DUST! that tan dust in the crevices on those radios brings back Iraq memories.. Who else who served down there remembers that tan dust that crept everywhere?
When I was kid in the mid 1970s, be lived in Baghdad for 3 years (dad was a diplomat). A few thoughts (even though those radios were probably made a bit after we were there): The poor AM selectivity makes sense exactly for the reasons shango suggested: not many local stations - all government run and part of the propaganda system although to us (who did not understand Arabic) they sounded like one might expect any foreign radio to sound - mix of music, news, morning radio shows etc. There were huge temperature swings (50C in summer to 5C in winter) so the poor tuning selectivity probably did reduce temperature changed induced tuning issues. The other reason for it might have been to make them foolproof to build. While the university in Baghdad apparently had a very well respected Electrical Engineering department (heard this from an Iraqi grad student who had come to Canada to study when I was a student), skilled technicians/tradesmen where not common and it probably was hard to find people who could do things like tune the IF after manufacturing or do other troubleshooting. There was not a large manufacturing presence in Iraq when we were there. They did make a few things - batteries come to mind - factories built and workers trained with the assistance often from Eastern Europe or Asia. I would guess that how radio manufacturing was started. Things like radios were hard to come by - imports of most things were restricted to conserve foreign currency, although there was one government store open only to diplomats and government officials that had the latest electronics and luxury items from the west (we bought a SECAM color TV there). Short Wave (HF) - interesting it seems almost unusable on those radios. It was lifeline for us - the only source of real news in English (or any language) from the BBC, VOA, CBC etc. Those western stations also broadcast in Arabic, so somehow reducing the sensitivity of the HF part of those radios might well have been deliberate. Or a manufacturing defect/error that the possibly semi-skilled production line workers did not notice or were unable to correct. We used (as did most westerners) some of the last models of the Zenith Trans-Oceanic radios (all transistorized by then). Really cool to see some Iraqi radios - thanks so much to shango!
Yes Asia and Eastern Europe invested heavily in these countries or rather cooperated with them, but in the 40-60s there were also Western manufacturers Philips and Thomson and earlier British manufacturers such as Roberts or Decca, Telsen, etc.
@@janmos5178 I didn't know those manufacturers had done much in Iraq that early - interesting! I do remember the French were helping the Iraqis build a nuclear reactor on the outskirts of Baghdad. Westerners (diplomats?) like us needed a permit (applied for weeks in advance) to leave the city on any of the major roads and there were government checkpoints on the roads to check that you had the proper permits. Somehow my dad found a road in the area of the reactor facility that didn't have a checkpoint - we took numerous Sunday drives down to that area along the Tigris River. Somehow I had figured out why dad liked going for a drive in that area but I must have been smart enough to also not say anything. Presumably dad's observations were sent to Ottawa and inevitably relayed to Washington and other western allies (the US did not have formal diplomatic relation with Iraq in those days, so no US embassy).
@@ElectromagneticVideos They weren't some big assembly plants because, as you mentioned yourself, radios and t.v. were expensive and the electronics and manufacturing infrastructure wasn't very extensive.
@@janmos5178 I guess it was an initial attempt to create some local industry to reduce the need for foreign imports and create jobs. I think back then the military was probably the largest employer, and long term that would have costly to maintain.
That bird at 7:50 sending "W" has a bit of chirp in his CW. LOL Seriously, the Eleno radio kit is a fantastic lesson for any student. I used them when teaching electronics. The magic wand is also an excellent demonstration of magnetic resonance at RF. For anyone assembling this kit, make sure that the loop is mounted on the ferrite rod with the small primary coil end (3 wires) facing the center of the rod. The rod works sort of like an OCF dipole where the high Z is located at the ends and if the coil is mounted backwards, there will be an impedance mismatch between the ferrite and the secondary (large) part of the coil. The result then is that the radio will tune, but not have a high Q or good sensitivity. 73 OM
Good stuff, like a book hard to put down. Learning am service from the meagerly available books in the 60's. I remember the transistor race. 4 xistors in parallel in output several in series as diodes...
Area of Iraq about the same as California. Iraq and Kuwait share a border, so the distance is zero. A radio station in Kuwait City is about 400 miles from Baghdad
Wow man I can't believe it I had one of those small ones like the blue one when I was a kid I actually remember buying it at a garage sale for $1 I wish I would have kept it
I don't remember how many radio stations we did have in Iraq back in the 80s (pretty sure not more than 2 stations) but I do remember that there were many local "stations" broadcasting pulsating noise to mask any non friendly stations coming from the neighbouring countries, especially Iran and Syria. Also there were one version of these big EIC radios made for the Iraqi army with some of the components missing including the main tuning variable capacitor. these radios were made to receive only one radio station which is the main Iraq propaganda station. but they were easy to convert back to normal radios.
I have an airline wards radio that advertises 17 transistors. The audio amp is push pull, but they just put two of the same transistors in parallel in the audio output, which I don't think is really necessary. Im not entirely sure what all the other transistors do since I've never had to pull up the schematic, because it still works perfectly.
The TDA2822 is a very common audio amp chip, and is indeed stereo with the capability of being bridged,. You'll find it in scads of cheap computer speakers from the 1990s and early 2000s. Portable radios, tape players, and CD players are actually its native application. I believe the OEM has discontinued it, but there are Chinese manufacturers stamping out clones.
We have those same birds in Finland that make that kind of sound. It would be nice to see you do a video on vintage finnish radio / tv if someone could send to you. We used to have our own electronics manufacturers in the past, of course our line sets work on 230V so not sure if you could power them up
brass was used a lot in TV tuners to reduce the inductance of the coils to tune them, vs. using ferrite to increase it. I wonder if this was so the Q could be higher of the resulting inductor?
I have a transistor radio that was made in the sixties. It's National. AM only, and made in Japan. It uses two AA cells. They came in both red and black, mine is black. It has 'Solid State' on the front. It would be similar size to the small one in the video, but mutch thicker. It's also heavy to what you would get now. It came in a box of sundries that I bought at an auction for $2 many years ago. It still works well, and I keep it in the kitchen where it can get some use.
Foreign stuff is generally straight forward and sensible. Mid 50's to mid 60's made in the USA is from another planet. The GE P-825 pocket radio, for example. The tuning and volume are on opposite sides and opposite planes to make sure you need two hands. Chrysler was trying to make an asymmetric car. Westinghouse audio amps where pin 1 and 2 on a pot is the tone and 1 to 3 doubles as the voltage divider for the preamp. The whole car is made of massive gauge steel, even the dashboard, but then the glove box and rear deck is cardboard. Speakers and TV's with expensive veneer and plywood, but the backs, and sometimes even the baffle, is low grade Masonite. Or you look up at the inside top and there is a a sheet of Masonite glued up there for no reason. Made with space age materials....
Poor quality ferrite bar ( coil at least),interesting if you could at sometime revisit these sets and substitute other ferrite antennas as an experiment.
Once nice thing about using the TDA2822 audio output chip in bridged mode is that you don't need a big electrolytic capacitor to couple the output to the speaker, saving one significant component.
You can try Czechoslovak Tesla radio from 60s like Tesla Dolly. They are cheap (approx 10 USD) and small so even post price should be low. All parts are domestic ones (but equivalent to european ones). They are LW or SW, MW and FM. FM is OIRT band, but you can listen strong FM station by mirror reception or retune FM part. And they are a little nightmare to repair because of small PCB with lots of components.
I'm pretty sure that these radios had an unfortunate encounter with a "golden screwdriver" type, given how far out some of the slugs are turned. As Shango mentioned that mediumwave is no longer used in Iraq, the radios might have been considered obsolete years ago and handed to a tween as a learning toy. I would be curious if part of the IF strip could be traced out. My suspicion is that a resistor may be placed across one of the windings of one or more of the transformers. Or, perhaps, they did something even more crude and used the entire primary winding instead of just the center tap. This would reduce selectivity and gain, but it would have the side benefit of improving treble response (at least in theory). I'm also quite curious how the squelch "feature" was implemented.
Instead of a "magic wand", you can use ordinary metal scissors. Bringing the scissor sharp end coaxially to the end of the ferrite rod increases the inductance (effectively increases the length of the rod); bringing the scissor ring perpendicular to the axis of the ferrite rod reduces the inductance (shorts the magnetic flux).
@@jeffk7734 Saudi Arabia,Kuwait,Egypt, Oman,Qatar,ton of Iranian stations,vesti fm from Moldova, some nights i can pick Romanian stations and radio Rossii from Moldova
Definitely makes sense that Iraq of all places already got rid of AM, they're still pretty prevalent here in the US and also Canada but most of Europe already seems to have shut theirs off. Unfortunate but apart from voice (mostly right-wing talk stations here and one or two music stations depending on where you live) AM was never very good anyways, at least as long as I've been alive. Still, interesting to see what the country we all least expected to make a radio (with shortwave capabilities, all during the Saddam dictatorship) make one, and have someone in the west review it.
@@ericdunn8718 Where are you? I’m in Western New York, and we’ve got the usual mix of talk and small town stations and Canada does a little bit better job of keeping some music stations on AM with a variety of music. If AM Stereo was heard and is done right it sounds just as good as FM. When they decided and agreed on a standard for AM Stereo in 1993, the end was near as far as AM was concerned and its decline. Never the less, it would be interesting to see what you can pick up in a part of the world where AM has gone all dark. When we had the eclipse back in April, it was neat to tune around AM and short-wave and see the way the bands were acting. It also would be interesting to see how iit is at either Antarctica what the bands would be like. It would be great to see how it would be in constant daylight and constant darkness.
@jeffk7734 Very true, I live in Michigan and AM as a whole is still relatively strong, at least in my area. At night on one specific radio I have I can get as far away as Quebec and even Philadelphia (which I imagine would normally be partially obscured by Canada and all the stations from New York, but this was at night in the middle of winter earlier this year, so there you go). I'm just meaning AM in general has really declined, even over the past ten years or so, there used to be a lot more local variety as per music but it's all talk and one or sometimes two music stations here, and I didn't get anybody playing music that one time I just described. I do remember hearing not too long ago that the few European countries that still had AM were recently shutting theirs down (apart from a few post-Soviet countries like Russia and Ukraine, the latter kept theirs around out of necessity because of the war), so that's where my assumption about Iraq doing the same came from.
So i guess these would be the Chevy Nova II of radios!? A sorta 80s Japanese designed product but assembled without the final quality control of the design its based on.
What are you talking about? Hong Kong Radios are very reliable....I have many of them, Sinclair Gasoline 6-Transistor Radio, a Zenith, a Canadian Tire Pulsar Radio, a Maple Leaf Radio, they all work perfectly. I find Japanese and Soviet Transistor Radios to often have issues, like being too quiet. Cheap Hong Kong Transistor Radios made between the 1960's up until the 1980's are of great quality in my experience, I have bought many of them at a local Flea Market, they always work.
You know, I'd be willing to bet the SW Squelch circuit can be disabled by opening or shorting a contact pair on the band switch. It's probably some kind of AGC controlled mute. AM and SW receivers fundamentally use all the same circuits the same way (they just have Ant and Osc. coils tuned for different frequencies) so that squelch has to be an extra circuit and has to be switched on and off with the band switch otherwise it would effect AM too.
There are too few transistors to made SW squelch circuit. I think that it is made just using silicon diode in detector instead of germanium one. So if the signal is weak, silicon diode voltage barrier refuse to open and detect it. Also the 3,3V power supply is too low for high sensitivity.
Interesting radios built a place we dont normally see. Almost acts like both of the larger radios use a ZN414 type of circuit ( wideband multistage RF amp with no IFs) although both clearly have IF cans.
_Squealing at approx. 570 kHz...It is the SUPERHET image signal._ There is an AM 1480 kHz in Santa Ana (Vietnamese Language). Take 1480 minus 910 (2 x 455 kHz IF) and you get 570 kHz. That is KLAC, correct? When I was a kid in Rochester NY, trying to pick up WGR (550 kHz in Buffalo) I would get the same squeal from 1460 kHz (then WHEC, later WAXC, now WHIC) in Rochester...that is how I learned of IMAGE SIGNALS... Dad's car radio NEVER did that as it used a 262.5 kHz IF strip.
Well done. A lot of such machines have been assembled in India and Arab countries since the 1950s in cooperation with Western then Asian companies. In this second radio not with the Toshiba chip there is probably an STMicroelectronics TDA series chip but I won't decipher the numbers anymore. It's not likely to be a TDA 7222 I think. Best regards.
Wow! I didnt know Iraq made transistor radios. Very interesting radios! I'll see if I can find one to add to my collection. What is the model of the little signal generator? I've been looking at them but I'm not sure which model to get. Great video! Thanks Ted
You could try getting some Yugoslavian built radios next. They are usually really cheap and used all domestic components. And sometimes they were even exported to the states when new, so with lots of luck, you might pick one up there
In the 1980s it was no longer only domestic components, as on TV Iskra one could find foreign ones as well. And in Yugoslavia's Slovenia Western companies had their assembly plants.
@@janmos5178 there were some foreign components in later devices, but not much. Perhaps some transistors, ICs and CRTs. I am not aware of any western companies that had assembly plants in Slovenia. Well, Ei Nis did produce vacuum tubes for Philips and Siemens/Telefunken when they stopped production and those Ei tubes are regarded as quite good (being made on Philips equipment)
@@michvod Korting (this one was bought by Gorenje) also as small suppliers to Grundig and Philips. ITT Schaub Lorentz was also hooked up. Iskra TVs from the 1980s had TDA ICs made mainly by Philips, e.g. the TDA 3506 or 5630 series.
2 days from Iraq to LA? Wow, it takes 3 days to get something sent 30 miles across water in the same country - Canada. Our postal system is in trouble.
Pars Electronic in Iran (the neighbour country of Iraq) made lots of radios and TVs that were clones of Toshiba or Grundig. This is the way third world countries went because they did not have the time ,money and knowledge (to enough degree) to design thier own circuits and make the machineries that assemble and test them.
The Q of a coil cannot usually be improved. Maybe they shunted good coils with a resistor, but that lowers gain too, or poorly matched. That is strange. Its built for sound quality. Maybe study diagrams of radios with bandwidth switches.
The part about this stuff I like is it reminds me that there are people in other countries just trying to make a living like us and not everyone there is the evil jerk we see on the news.
Those slashes on the dial makes it appear as 1550 to 11550 or something. Interesting that something made there has English words and numbers. Interesting video.
The wide bandwidth is a problem with those cheap analog radios from India that were featured on several YooToob vids a couple of years ago. Similar construction vibe too. I like the political front end theory though.
This particular video is almost 100% radio technical stuff, with minimal typical Shango commentary.
Shango's commentary is what makes the channel so unique and entertaining.

alot of them are just used as diodes
they probably used 2 in parallel so they could uses cheaper/lower power types 😉
Its always nice when the Eurasian collared dove chimes in.
Like from Brazil.
Looking at whats on the transparent plastic front of the grey radio, some guy REALLY loved this thing.
The TDA2822 is a very common audio amp chip, and is indeed stereo with the capability of being bridged,. You'll find it in scads of cheap computer speakers from the 1990s and early 2000s. Portable radios, tape players, and CD players are actually its native application. I believe the OEM has discontinued it, but there are Chinese manufacturers stamping out clones.
i have a Toshiba CRT TV from the early 2000s that uses a clone of it, cant remember number ..
Nice video. Tell us more about the sig-gen.
We have those same birds in Finland that make that kind of sound. It would be nice to see you do a video on vintage finnish radio / tv if someone could send to you. We used to have our own electronics manufacturers in the past, of course our line sets work on 230V so not sure if you could power them up
Being from a hot hot hot... arid clime, yep, they function.
brass was used a lot in TV tuners to reduce the inductance of the coils to tune them, vs. using ferrite to increase it. I wonder if this was so the Q could be higher of the resulting inductor?
I have a transistor radio that was made in the sixties. It's National. AM only, and made in Japan. It uses two AA cells. They came in both red and black, mine is black. It has 'Solid State' on the front. It would be similar size to the small one in the video, but mutch thicker. It's also heavy to what you would get now. It came in a box of sundries that I bought at an auction for $2 many years ago. It still works well, and I keep it in the kitchen where it can get some use.
That Elinco radio kit is very good. I built one about 20 years ago just to learn how to fully tune and align the radio.
Foreign stuff is generally straight forward and sensible. Mid 50's to mid 60's made in the USA is from another planet. The GE P-825 pocket radio, for example. The tuning and volume are on opposite sides and opposite planes to make sure you need two hands. Chrysler was trying to make an asymmetric car. Westinghouse audio amps where pin 1 and 2 on a pot is the tone and 1 to 3 doubles as the voltage divider for the preamp. The whole car is made of massive gauge steel, even the dashboard, but then the glove box and rear deck is cardboard. Speakers and TV's with expensive veneer and plywood, but the backs, and sometimes even the baffle, is low grade Masonite. Or you look up at the inside top and there is a a sheet of Masonite glued up there for no reason. Made with space age materials....
These radios are bulletproof, pun fully intended.
This is Iraqi Radio Al-Qaythara, which is a collection of the best radios in its power
Very unusual find, thanks!
Poor quality ferrite bar ( coil at least),interesting if you could at sometime revisit these sets and substitute other ferrite antennas as an experiment.
Buen vídeo,saludos desde Chile.-
And what lovely unused space inside for special customization, ( just use your imagination, it’s the Middle East.)
Once nice thing about using the TDA2822 audio output chip in bridged mode is that you don't need a big electrolytic capacitor to couple the output to the speaker, saving one significant component.
theres a TDA7052 thats similar but only a bridge amp that needs no external caps at all apart from a supply decoupler
You can try Czechoslovak Tesla radio from 60s like Tesla Dolly. They are cheap (approx 10 USD) and small so even post price should be low. All parts are domestic ones (but equivalent to european ones). They are LW or SW, MW and FM. FM is OIRT band, but you can listen strong FM station by mirror reception or retune FM part. And they are a little nightmare to repair because of small PCB with lots of components.
I'm pretty sure that these radios had an unfortunate encounter with a "golden screwdriver" type, given how far out some of the slugs are turned. As Shango mentioned that mediumwave is no longer used in Iraq, the radios might have been considered obsolete years ago and handed to a tween as a learning toy.
I would be curious if part of the IF strip could be traced out. My suspicion is that a resistor may be placed across one of the windings of one or more of the transformers. Or, perhaps, they did something even more crude and used the entire primary winding instead of just the center tap. This would reduce selectivity and gain, but it would have the side benefit of improving treble response (at least in theory).
I'm also quite curious how the squelch "feature" was implemented.
Instead of a "magic wand", you can use ordinary metal scissors. Bringing the scissor sharp end coaxially to the end of the ferrite rod increases the inductance (effectively increases the length of the rod); bringing the scissor ring perpendicular to the axis of the ferrite rod reduces the inductance (shorts the magnetic flux).
very interesting benice to get one from the 70s before the revilution.
Radio Kuwait broadcast at 600kw power at the day time and we have one AM station left in iraq “Radio republic of Iraq” on 792khz 20kw power
What are you able to pick up at night with only one AM station in Iraq?
@@jeffk7734 Saudi Arabia,Kuwait,Egypt, Oman,Qatar,ton of Iranian stations,vesti fm from Moldova, some nights i can pick Romanian stations and radio Rossii from Moldova
Definitely makes sense that Iraq of all places already got rid of AM, they're still pretty prevalent here in the US and also Canada but most of Europe already seems to have shut theirs off. Unfortunate but apart from voice (mostly right-wing talk stations here and one or two music stations depending on where you live) AM was never very good anyways, at least as long as I've been alive. Still, interesting to see what the country we all least expected to make a radio (with shortwave capabilities, all during the Saddam dictatorship) make one, and have someone in the west review it.
@@ericdunn8718 Where are you? I’m in Western New York, and we’ve got the usual mix of talk and small town stations and Canada does a little bit better job of keeping some music stations on AM with a variety of music. If AM Stereo was heard and is done right it sounds just as good as FM. When they decided and agreed on a standard for AM Stereo in 1993, the end was near as far as AM was concerned and its decline. Never the less, it would be interesting to see what you can pick up in a part of the world where AM has gone all dark. When we had the eclipse back in April, it was neat to tune around AM and short-wave and see the way the bands were acting. It also would be interesting to see how iit is at either Antarctica what the bands would be like. It would be great to see how it would be in constant daylight and constant darkness.
@jeffk7734 Very true, I live in Michigan and AM as a whole is still relatively strong, at least in my area. At night on one specific radio I have I can get as far away as Quebec and even Philadelphia (which I imagine would normally be partially obscured by Canada and all the stations from New York, but this was at night in the middle of winter earlier this year, so there you go). I'm just meaning AM in general has really declined, even over the past ten years or so, there used to be a lot more local variety as per music but it's all talk and one or sometimes two music stations here, and I didn't get anybody playing music that one time I just described. I do remember hearing not too long ago that the few European countries that still had AM were recently shutting theirs down (apart from a few post-Soviet countries like Russia and Ukraine, the latter kept theirs around out of necessity because of the war), so that's where my assumption about Iraq doing the same came from.
So i guess these would be the Chevy Nova II of radios!? A sorta 80s Japanese designed product but assembled without the final quality control of the design its based on.
I'd love it if you could possibly get hold of one of those "pre tuned" radios from the dprk. Pretty much impossible, I suspect.
Those radios apparently were designed so you can *ONLY* listen to the "Fearless Leader."
Considering that Saddam Hussein was very much in power when these radios were built, that is quite probable.
What are you talking about? Hong Kong Radios are very reliable....I have many of them, Sinclair Gasoline 6-Transistor Radio, a Zenith, a Canadian Tire Pulsar Radio, a Maple Leaf Radio, they all work perfectly. I find Japanese and Soviet Transistor Radios to often have issues, like being too quiet. Cheap Hong Kong Transistor Radios made between the 1960's up until the 1980's are of great quality in my experience, I have bought many of them at a local Flea Market, they always work.
Interesting radios.
Radio kit, tuning kit. Never saw one of those before. Interesting. What is its purpose?
You know, I'd be willing to bet the SW Squelch circuit can be disabled by opening or shorting a contact pair on the band switch. It's probably some kind of AGC controlled mute. AM and SW receivers fundamentally use all the same circuits the same way (they just have Ant and Osc. coils tuned for different frequencies) so that squelch has to be an extra circuit and has to be switched on and off with the band switch otherwise it would effect AM too.
There are too few transistors to made SW squelch circuit. I think that it is made just using silicon diode in detector instead of germanium one. So if the signal is weak, silicon diode voltage barrier refuse to open and detect it. Also the 3,3V power supply is too low for high sensitivity.
@@xsc1000 Yes.
Will these be acceptable during the time of Ramadan
I guess if you don’t eat them… 😂
The Black one LOOKS IDENTICAL to one I had from PHILIPS!
Interesting radios built a place we dont normally see. Almost acts like both of the larger radios use a ZN414 type of circuit ( wideband multistage RF amp with no IFs) although both clearly have IF cans.
neat stuff wild how us old radio nerd to not get bunt out on different stuff love it DHL rules shipping then wow. gloves ?

Can anyone point me to the video where Shango first starts using the tinySA?
Looks like one of the electrolytic caps. has a date code of 8409 on it. Bird is the word.
Impressive something that late has no ICs, but I guess it's not that surprising for a country with a less developed electronics industry
As long as you can receive KNX, you'll be happy. 😀
_Squealing at approx. 570 kHz...It is the SUPERHET image signal._ There is an AM 1480 kHz in Santa Ana (Vietnamese Language). Take 1480 minus 910 (2 x 455 kHz IF) and you get 570 kHz. That is KLAC, correct?
When I was a kid in Rochester NY, trying to pick up WGR (550 kHz in Buffalo) I would get the same squeal from 1460 kHz (then WHEC, later WAXC, now WHIC) in Rochester...that is how I learned of IMAGE SIGNALS... Dad's car radio NEVER did that as it used a 262.5 kHz IF strip.
Well done. A lot of such machines have been assembled in India and Arab countries since the 1950s in cooperation with Western then Asian companies. In this second radio not with the Toshiba chip there is probably an STMicroelectronics TDA series chip but I won't decipher the numbers anymore. It's not likely to be a TDA 7222 I think. Best regards.
Lack of selectivity and alignment on the radio’s behalf bringing the listener into alignment through very selective reception?

Hi Shango and fans🎉❤
Assembled in Iraq is how it should read... right? THANK YOU.
Wow! I didnt know Iraq made transistor radios. Very interesting radios! I'll see if I can find one to add to my collection. What is the model of the little signal generator? I've been looking at them but I'm not sure which model to get. Great video! Thanks Ted
Its called Tiny SA Ultra and there is smaller Tiny SA. Both are designed as spectrum analyzers and generator function is just a little add on.
You could try getting some Yugoslavian built radios next. They are usually really cheap and used all domestic components. And sometimes they were even exported to the states when new, so with lots of luck, you might pick one up there
In the 1980s it was no longer only domestic components, as on TV Iskra one could find foreign ones as well. And in Yugoslavia's Slovenia Western companies had their assembly plants.
@@janmos5178 there were some foreign components in later devices, but not much. Perhaps some transistors, ICs and CRTs. I am not aware of any western companies that had assembly plants in Slovenia. Well, Ei Nis did produce vacuum tubes for Philips and Siemens/Telefunken when they stopped production and those Ei tubes are regarded as quite good (being made on Philips equipment)
@@michvod Korting (this one was bought by Gorenje) also as small suppliers to Grundig and Philips. ITT Schaub Lorentz was also hooked up. Iskra TVs from the 1980s had TDA ICs made mainly by Philips, e.g. the TDA 3506 or 5630 series.
So these Radios (at least as supplied) were in concept rather like the German Volksempfanger.
Pretty interesting. I'm gonna make me a big industrial one.
2 days from Iraq to LA? Wow, it takes 3 days to get something sent 30 miles across water in the same country - Canada. Our postal system is in trouble.
I suspect it was a small airplane only for cargo and had some free time but I don’t really have anything to back that up with.
You just sold me on that tiny See Sii siggy gen. Just picked one up on ebay.
The chip makes it a far more efficient set. I guess power can be sporadic in Iraq and long battery life is important.
Are you going to host the debates on the old television?

I'd love shango to get hold of an north korea radio and see how they tune their radios
Really cool shame no FM they would be useless here

Excellent ! Who would think that Iraq made anything... Except oil. Please try for some future video to find something from North Korea if possible...
There is none who can send it :-)
Strange, it seems as though the IF transformers have too broad of tuning/low Q to cause poor selectivity. Sensitivity seems decent.
Pars Electronic in Iran (the neighbour country of Iraq) made lots of radios and TVs that were clones of Toshiba or Grundig. This is the way third world countries went because they did not have the time ,money and knowledge (to enough degree) to design thier own circuits and make the machineries that assemble and test them.
Interesting... Maybe the IF intentionally dampened. Have a look if the IF tanks have resistors across??
The Q of a coil cannot usually be improved. Maybe they shunted good coils with a resistor, but that lowers gain too, or poorly matched. That is strange. Its built for sound quality. Maybe study diagrams of radios with bandwidth switches.
The Harp shown on the radio is an Ethiopian “ Davidic “ Harp . It is said to be the same kind of harp that David used.
Deveria testar rádios brasileiros da marca "Motoradio" dos anos 80 e 90, acho que ia gostar deles.

The part about this stuff I like is it reminds me that there are people in other countries just trying to make a living like us and not everyone there is the evil jerk we see on the news.
Those slashes on the dial makes it appear as 1550 to 11550 or something. Interesting that something made there has English words and numbers. Interesting video.

What is this LOGGING on the dial at 27:00?
The wide bandwidth is a problem with those cheap analog radios from India that were featured on several YooToob vids a couple of years ago. Similar construction vibe too. I like the political front end theory though.
