AM radio is very important to our Emergency Alert System here in the USA. We have 50KW stations that are very important. That said, I hope MW (AM broadcast) never goes away. It would do so much better if most of the stations offered music, as they did 30+ years ago. Talk radio is fine…but not on every frequency !
I'm a talk radio fan, I stopped listening to music years ago. The Denver Colorado area has some decent talk radio shows that I enjoy as I'm sick and tired of the NPR indoctrination on FM. The AM talk shows are somewhat conservative, not anti vaxers just rational people willing to have dialog with people suspicious of the vaccines safety. As for music, I think our local stations are either religious (nothing wrong with that just not everyones cup of tea) or Spanish music.
@@mianahmad5918 all of it - it needs well tuned antenna, enough RF gain and IF gain and possibility for IF channel to be well tuned (to be able to get narrow enough IF band)
Russia also had very high powered MW stations to cover a large continent, so living close to say a 1000Kw or even 2000Kw transmitter could overload a normal radio.
Interesting, I didn't realise electrical items were graded in the former Soviet Union. Can you please tell us more about this grading system? Is it still in place?
@@freedomvigilant1234 Yes, all items was graded, grade is first digit in model name. Highest is "0", lowest is 4. For each type of device was standarts, I cannot find it in internet, but I believe it is possible.
It is very pleasant to listen to such a clean broadcast. Not clogged with industrial interference. The gaps between stations (crystal) are practically noiseless. As if it is a setting with noise suppression.
I got really sad when you told you finished a video on something and don’t post it but got relived when you told it was gonna be uploaded at Sunday. I love your vids and you started my hifi enthusiasm (old HiFi equipment that needs fixing)
In the Midwest, on long wave around gray line time I have actually heard some DX from Europe and also some stuff from Asia from time to time it’s out there, there’s lots of beacons and things left on those frequencies to
I've had those variable caps break, the screw breaks off the ceramic plate, and those polystyrene caps (clear case) have very weak leads, so don't bend them much, also they permanently drift if you heat them so take care soldering them.
You could cut the lead of the dud capacitor as close to the PCB (component side) just enough that it makes no contact, and leave it looking original... Or desolder the copper side so it makes no contact with the pad, and solder in the replacement at a different point...
I don't know if you know that in the USSR, in the name of the equipment, the code of its class was encrypted. The smaller the number, the better the device. This receiver has the number 403, the first number 4 means that the receiver is of the fourth class, that is, the simplest possible. And if the number started from zero, then this is a top-class receiver, with a large number of bands and has many additional features. As an example, the radio receiver "Leningrad-010-stereo". The next digits indicate the development (modification) number, in this case it is the third. In our country (Russia), many such receivers have survived. Almost no one uses them anymore and for this reason they are massively thrown away. The owners give them away for free, just not to throw them away. Hope you weren't charged a lot for them.
@@shango066 In IF+Osc stage this radio has Germanium GT309 transistors (with quite low NF). Audio stage Si+Ge transistors. Beside it if they have rhombus symbol it means Xtra good! For militärt use!
You picked up a station in Mandarin Chinese there, right when you started tuning those trimmer caps. Sounded like a gov't one. Was that on MW? Are there Chinese MW broadcasts from the US? Apparently long wave broadcast DXing was a thing, often going intercontinental - google "long wave broadcast dx" and there's a page by a NZ DXer about it.
Definitely, I think it still is a thing too if you've the tuner for the job. Would be cool if Shango066 ever went to the East Coast (can't see it, and can't say as I'd blame him!) to see if any of his collection could get Europe or the UK. For the record, I used to listen to LW fairly regularly in school. Atlantic 252 if anyone else remembers them lol
Tks fer good show. Setting in park ...have my xd d -219 running the show. Using a home made wire. It's young. So I watch the fine sets you work on. And watch you win. Against old radios tks om!
Wait until you try the Selena- series of radios or the Spidola- Series. I owned both, the export versions that had the standard FM frequencies rather than the Russian frequencies for FM. These radios were heavy and bulky and, unfortunately, crappy adjusted at the Baltic factory. But once adjusted properly they were really good receivers.
I am impressed by the sensitivity of this receiver. It was probably intended to be used for the deep interior of the now-defunct Soviet Union. Its use was probably "discouraged" near international boundary zones, as it could potentially pick up broadcasts originating from the other side of the Iron Curtain.
Well done! I'm pretty sure this radio shares the same design and schematics with the Sokol 403. Since I have the Quartz 404 Olympic (which is, again, based on Sokol 403 with upgraded transistors), I can tell these radios are very sensitive, very selective, and very quiet between stations.
Your observation of selectivity is interesting: in the USSR they did not have SAMS photofacts but they had several book series of different publishing houses where they published most of consumer products schematics with principles of operation explanation, PCB, BOM and coils data, so for this radio one such issue says that first IF has bandwidth of 12-16kHz (two capacitively connected tanks) and the second IF has 30-40kHz bandwidth both at -6db, which combined is giving close to standard bandwidth. ITU's region I low broadcast band plan is 9kHz bandwith with 9кHz spacing, so my guess is the combined effect of narrower band with the relatively long dial scale are giving this selectivity.
They forbid me to use this radio. So I asked them to get me the successor model but they said they couldn't find it. Ba-dum tsss. 403 forbidden 404 not found.
It is really exciting how many middle wave AM stations are still active in US. In Russia LW/MW bands are almost empty, all you can hear is noise and static.
Yes FM works much better and gets around all the fuel pump and other electronic noise in today's cars. A.m. is almost completely unusable that's why everyone is going to FR-S
The electronic diesel injection systems on big rigs make am radios horrible to hear when you aren,t close to the transmitter. You can take your foot off the hammer and most of the static goes away.
The complete opposite of Grundig radios, superb build quality but diabolical selectivity! Had several Grundigs that play two stations at the same time with the aerial up, only way to get the weaker one to go away is to put the aerial down!
Do you want a couple of free portables? Specifically a 5 inch GoldStar branded portable, and a Panasonic Ranger 505 B&W portable. I picked them up for free locally to save them from scrapping but I don't really have a usage for them. I'll cover shipping if you agree to do a video on them. The GoldStar I believe is early 70s, the Pansonic is late 1970s and looks to have been owned by some sort of industry worker as its covered in various decals for steel works related companies. Plastics and glass appear to be in good shape on both.
13:26 shango, believe me, its wrong to tune at the low band with the capacitor-trimmer oft the input-circuit, you have to do it with the ferrite-coil (move the coil-body on the ferrite-rod a little) ! Then on the high-side oft the band with the trimmer-C again...
@@shango066 o.k., its a bit strange for me, all radios I know have this possibility, seperate for every band... then you did right to only trim on the high side... but it works so well, good job !!
@@shango066 This part must be moved in the place with the wound coil along the core. The part is not poured onto the core, it is fixed with wax. It is enough to warm it up with a hair dryer. ))
Interesting the top end of the dial on that radio reads 2000 so does that mean it will receive up to 2mhz? Is there anything up that high on the AM band? Nice video as usual, thanks.
Russian radios are excellent for sensitivity and selectivity... oddly, with the great selectivity they are usually also very sparing with the numbers on the dial scale !
Nice radio and you able to get them going fast. Did you hear how the fcc going to try to save the cb radio band. Let cb radio be able to use fm as well. Think there a bit late on trying to do anything to save cb radio.
I am just wondering if You Lost your old analog TV CH 6 in LA? I here that some other low power analog TV stations out in New york went off the Air back on July 13th. So I am wondering if you will still have Your analog Channel 6 When you next restore & fix up an old TV again. Please Let Us Know
Most likely, yes. The FCC mandated that all remaining analog low-power TV stations had until July 13 of this year (2021) to shut off their signals. I think there may have been some stations that were granted a special temporary authority to broadcast the NTSC audio carrier so that radios that can tune to 87.7 MHz can still pick the stations up while they use the remainder of the highly efficient ATSC carrier to transmit on virtual channel 6.1. With that said, Alaska has been granted a special temporary authority to broadcast analog LPTV until 2022.
I came here for the News. 8 ) *Thanks!* Judge too sceeered to stand with his ruling, against gun ban, while being appealed. Perhaps Zip Ties will be 'weapon' of choice against Trolls. Then, what would i do with all my Rope? 8\ Race always takes a bit of the bore out of stories for some.
В СССР о приемниках такого типа говорили - "хорошей музыки не ловит". In the USSR, they said about receivers of this type - "he doesn't catch good music."
reason why i dont collect radios. theres alittle less than 10 am stations and about 10fm stations in my area, and i dont like a single one. its all country, pop, rock or chirch.
@@vladimirrex1007 у 209 го переключение диапазонов вымораживает, все время этот барабан дергать приходится, а у 222 как по мне стрелочного с метра не хватает, а так оба приемника по своему хороши
