Equipment / Re: Question about radiation.
« on: July 01, 2019, 1826 UTC »
Yeah this is a very risky case. And I still wonder if I have some of this stuff ingested or something. Thatís what keeps me in panic mode all the time when I think about it. I think Iíll be better off with hopefully being able to swap it for a non radioactive device that still looks nice.

Hereís a picture I took long time ago. Just posted for examination. The paint looks white and a little brown. Also the knobs are very brown while the arrows are perfectly white. In the dark the glow stops very quickly after turning off the lights in my room. Only the switches and some dials keep glowing low green ish for about 10 minutes max.

Thanks for the comment, I really need as much info as I can get before I decide to take the radio back home leaving me in a very big risk. So I wonder if someone can figure out the paint of it. Itís the only picture I have left and I canít take a sharper one as the radio isnít here at the moment.

Any further details are highly appreciated!

Thanks for the information, I highly appreciate it. Currently most radiation detection devices are above my budget at the moment. If I had the money I would bought one that would do the job. I think I just try for swapping it for a different radio I like to get. If the owner doesnít want it back I will probably place the device in a corner of my room far away from everything I walk across. But due to limited space itís alnost impossible to find a safe spot to store it. I surely will buy a Geiger counter that detects all later when I have the money for it just in case so I can check the whole room I live in if there are any suspicious detections around. My room is not ventilated, always dusty very quick. And all I have is a bed and the shack next to it due to lack of space. All is in a single room with almost no areas to walk around as itís so small here..

The only thing I noticed lately is that my fingers and other body parts are feeling a little weird. Not continuously but sometimes when working with small parts itís easy to feel my fingers cramp for a while and like unable to move them for a minute or so.

From what I gather Tritium seems less harmful than Radium. And I think itís likely Radium paint as it was very popular back then. Even though the paint seems decaying a lot and almost isnít glowing anymore, it still is radioactive and it glows when I shine UV light on it for like 10 minutes max on the thickest parts (the switches have a thick dot on top that seems to have to most glow still present to this day.)

Even though itís a nice piece of history, I want my safety to be first always. So Iím thinking about swap trading it for a different radio that isnít painted with this stuff (I hope he want to accept the deal) so I donít have to worry any longer about being contaminated with this stuff. Yet I will really miss this beautiful piece because of my connection with it. It gives me a sad feeling to think about getting rid of it still. I was so proud of having this radio as my first tube radio and historical piece of the war. Especially since itís from the Russians where my interest in radio began because of the discovery of the Buzzer when I was young. Still hard to find the right choice. Iím just struggling with two thoughts: Get rid of it to be safe and sound, and the second thought: Keep this beauty as itís tour first piece of your collection. And itís all original without any modification. The inside of the radio looks still brand new.

I hope to find more tips from experienced collectors here. Is the risk really that big of having a luminous painted piece of history in my little room where I sleep and live all day? Or shall I get rid of it before flakes of Radium fall on my other big radios and alike till almost every corner and vintage piece in the room has some dust on it somewhere..? It isnít covered with any glass or protective housing. I can touch the paint directly with my hands. And if it falls off, it will be likely everywhere when I walk by to get to my bed as it stands right next to it. I have no place to store it otherwise. All I have is a little apartment with only one room to keep all things together...

Thanks for the quick response all. And nice to know where to buy Geiger Counters as I want to check if my room has traces behind from moving the radio (and my hands after operating this thing for a long time) to see if anything has been fallen off on my other radio it was standing on top off.

Yeah it would be a interesting thing indeed to check what kind of isotope the USSR used for their equipment. I heard a news report somewhere that they used to paint the walls of bunkers with radio luminous painting to keep it lit. And is still present over Russiaís abandoned places.

I donít have any kind of equipment right now to measure anything except the glow on the front. I wonder also if the Americans have also used luminous paint on their BC-348ís like Russia did..

I have the radio currently in another location because it was needed to get new grease for the dynamotor. So as itís still there where I bought it a few years back, Iím just wondering if I should just pick it up and bring it back home or maybe leave it there for a swap trade or something.

Any tips and other info is highly appreciated! I still wonder if I have some particles inside my body. If so, any way to detect it easily or is it just not much to worry about? The owner who sold me the radio, and now has repaired it, does this work for over 58 years. And has no health problems at all. Which makes me wonder. He has so many surplus radios and alike. Also aircraft panels and radio direction meters which he repaired and all have the original luminous glow. Some fainted out, and others sometimes slightly glow.

I just want to be save and not being continuously worrying about being in a bad toxic situation.

Equipment / Question about radiation.
« on: June 30, 2019, 2204 UTC »
Hi all, I have a Russian BC-348 J receiver laying around and Iíve noticed that it has a lot of radio luminous paint on almost any part for operation. The switches still glow slightly. All knobs are glowing and even the text on the front plate is all made up of radio active material to make it ďglow in the darkĒ..

Now Iím wondering what I should do with it. As I simply donít like the risk of being in front of a high level of radiation all the time.. I kinda want to get some helpful tips on what choice to make. I have a strong connection to the receiver as it was my first tube radio.. and it is kinda hard for me to get rid of it. But itís bothering me since I know that itís been radiating next to my bed all night long. And I am easily paranoid by the stuff I read regarding radioactivity and itís nasty effects. I barely touched the radio after I discovered this. Itís doing nothing at all for now except sending a lot of radiation..

Itís a painful decision as I had a lot of pleasure in the first few years of every day operation. Before I knew I was contaminated with radiation every day... The radio luminous paint is also kinda fading off. Just like little tiny parts slowly fall off without noticing after operational use. I am worried that I accidentally ingested or inhaled some little parts of it. But I have no real proof of it that the material has entered into my internal body.. like usual I just operated the radio like a computer and did eat after without washing my hands. So I wonder what the risks are and so on.. This is my worst discovery so far in my SWL hobby..  :(

Link to the discovery:

https://youtu.be/bmwKEhpqZPw?list=PL8UE9zbbkEisBK9uhpfYsF5-JeAp-cacU

I will appreciate any help, comments, and tips regarding what choice is the best. Itís a nice radio and a piece of history. All still original and never modified by anyone who owned the radio before I did.

Equipment / New in my collection R210
« on: June 03, 2019, 1442 UTC »
Just arrived, a working R210 Reception Set. Looks nice all works fine. Only the outer cover is a little damaged but the inside is like new. No dust or other faulty parts. All tubes shiny and nice in order. Iím happy with it.

De only downside: The frequency scale isnít accurate. When I tune to my usual station I listen to all day, which normally is on 4625 KHz, shows up on the 3rd band of the scale at 4.55 (4550 KHz). But the rest is all working nicely.

« on: June 03, 2019, 1430 UTC »
I love the history of radio spying and alike. From one time pads to numeric code and huge bulky equipment all in a single base station with bulletproof walls and the smell of old electronics. Cold and dark, hidden in the middle of nowhere. Thatís what my kind of radio shack eventually will be looking like. Inspiration is all around when just digging into it. :)

Hereís the circuitry on the inside. It looks messed up to me. As a beginner, I have no idea on how to clean this all out and if the mess is a sign of a leaking capacitor or something. This stuff is really like a maze to me. I donít know where to start nor end.

@IZS4 - Thanks for the quick reply! It covers exactly what I needed to get. I wonder if itís safe to get some voltage into it and turning it on or disassemble it to see if anything is wrong on the inside.. on the outside everything looks good. Only dust is the faulty part. On the inside of the battery case, it looks also kinda dirty. Not that much but a few black spots on the sides are visible. Maybe also dust to clear out. No signs of leakage on the spring plug which sounds good to me.

Hello, I got a radio yesterday from a local source. The owner didnít know what to do with it so he gave it to me. I also canít easy find he description on the web. So I made a link o Imgur with the pictures of the device with all details from the outside and the kind of batteries that came with it in the bag. I guess the yellow ones are the originals. As they donít have a modern brand name and only a number painter on them. They also seem to have mah, which makes me think those were rechargeable. I appreciate the comments and I hope to find the right kind of manual to make this thing work instead of just messing it up while trying to get it working without knowledge. The link is below:

For me, it all started After my granny gave me an old handheld world receiver with shortwave on it. I had no clue as to what it was, and listened to it for hours a day, started when I was 9 years old. Then later when I was at a local flea market, I stumbled across an old pile of books that were mostly covered in dust and almost unable to read due to moisture damage. One of those books I was looking at, had weird text on the cover. Leading to the reason of picking up that single book to inspect out of curiosity. I opened the book and some kind of what I think it was a reading card to mark the last page of the book the previous owner was reading to, fell out of it. As soon as I picked it up off the ground, and the guys who were selling the books were not noticing, I simply took just that little piece of paper and put it in my pocket before I put the book back on the pile it was laying. Later that day when I went back home, I decided to take a look at the weird language that was not only on the book but also on that little piece of paper that fell out of it. (I didnít know it was Russian language, especially not when I was just a little kid.) I typed in some words on the web and I found out it was linked to a radio broadcast located in Russia. And that it was transmitting 24/7 on the shortwave band. And thatís how my journey began.

Now at the age of 23, Iíve been following this station for about 10 years. And my interest has grown up to the point of collecting Russian radios dating back to world war 2 and the USSR.

The inspiration to all this work on collecting nice pieces of old shortwave related stuff all linked back to that single day at the flea market.

But even before that I was already interested in the shortwave band. As I heard low quality amateurs voices through that simple world receiver. I became hooked to it. I had no idea what I was listening to. As a kid, I was always wondering what it could be, and my mind was like ď is this the police? Are those people military agents? Is this the phone in the living room Iím listening to? And the list of thoughts goes on and on.Ē

I remember me always sitting alone in the dark attic while my other sons were playing video games or watching tv. All I needed at that time was my little world receiver that has been a real gift to me especially as I was still a child who always was busy with discovering things. And like now, 10 years later, I never changed my habits. I canít sit still doing some pointless stuff like watching propaganda tv or news that was always about negative things. Iím still the same as I was back then. When I just listen to shortwave, it makes me feel young again. A lot of memories pop up every time at night when the tubes are glowing and keeping me warm at night.

When I was at the age of 6 or so, I always started building things from simple disassembled components. I had a simple science kit based on electricity that I played with a lot. And I also used radio transmissions to drive a wireless car on the local road. So I can understand now when I look over my past life, I have been dealing a lot into radio even without really thinking about it. Like driving a radio controlled car. I enjoyed that for many many years. And often modifying electronic stuff also bought me to the collection part I am into since a few years. Repairing computers was the first successful project I have been diving into. And now to this day, I want to do more than just building and repairing computers only. So radio comes into my next hobby to have fun with.

I feel really really uneducated when it comes to radios, as it is completely new and different than what I already did with pcís. So I am just entering a whole new field of opportunities and fun to spend years of time into. Especially now as all the pcís I once bought from the dumb are recovered and working fine. I need something new to work on and learn from.

I hope that I will be able to repair all kinds of old radios especially in the future. Just like I did with those old vintage pcís. But itís still a lot of hocus spocus to me. New stuff like the life of tubes, SWR meters, and antenna designs are really confusing at the moment as I never heard about those topics. But I have enough spare time so I will be diving into those things little by little.

Overall, me as a 23 year old guy, am extremely interested and hooked to shortwave and all about radios. Especially the older ones. My experience with new stuf is that it is easy to fail over time. So now I need to see if that applies to old tube radios (which I doubt, due to their long history and the fact that they still work like new).

So thatís my short overview of how I got into radio at the very early age of 10.

If you made it to this end, I hope you enjoyed my little writing about my early experiences and how it evolved into what I am now. :)

Kind regards,

@ str - I only get signal through it when I only connect the center conductor without connecting the shielding. If I connect the shielding by screwing the coaxial cable to the plug of my SDR, all signals are completely gone and the waterfall is empty. So I assume that the SDR is just in a bad condition.

@ Josh - I am thinking about buying a better SDR anyway, so I appreciate the tip. As Iíve seen many different kinds of SDRís on the web, I am at the moment just wondering which one is the best one to get. I first was thinking about buying the Kiwi-SDR, but the SDRPlay also looks promising to me. So I need to make sure that I donít waste my money on buying a SDR that doesnít seem to fit my needs. I just want to listen to shortwave mostly. Besides that a little on the fm side (77 - 108 MHz).

The SDRís I am looking at are the following:

Kiwi-SDR
SDRPlay
HackRF
Win radio pci card
RTL-SDR v2 or v3

Just wondering which one is the most fair one to get. I just need good performance just like my analog radio does.

Kind regards,

SDR - Software Defined Radio / RTL-SDR maintenance help needed
« on: April 28, 2019, 0902 UTC »
Hey there, I have a RTL SDR dongle that needs some maintenance. I measured the two coaxial plugs on the dongle which both seem to have short circuit in them. I tried to disassemble the dongle but I canít even slide the side panels off after removing the screws. So Iím wondering if itís worth the time to try and get it disassembled and get new coaxial connectors. Or just buying a better one? Itís not a high end dongle so I just need some advice on what to do with it. I bought it for quite a bit (Ä58,-)

Any tips and info is appreciated.

Kind regards,

Equipment / Re: Questions CB and TX base station project
« on: April 28, 2019, 0841 UTC »
Yes they surely sound better than my SDR, high end Roland music gear, and Some expensive transistor radioís i bought when I was still a kid. The R-250M is the most clear in sound even with the BFO wheel I can listen to my favorite nostalgia on 4625KHz at night without interference issues. I have only one little thing that I still need to figure out how to operate it. While listening to the 80 meter band especially. The BFO has a high pitch noise that I canít get rid of. While turning the wheel to either the left or right end, thereís a second noise always to be heard right through the amateurs speaking.. which makes it almost impossible for me to listen clearly to them. I think it links to a lot of RF-interference as I always see on my SDR radio spectrum in the 80 meter band. So maybe the focused lines on the spectrum, spreaded on the waterfall like a fence, is the cause for the second tone on the BFO mode. On 4625KHz there arenít that many of those lines to be seen so it makes sense that that might be the issue.

By the way, the next thing I would love to add to my shack is a surplus LW/AM radio only. As the R-250M doesnít cover those bands. I just bought a active mini whip yesterday and itís mounted outside in my garden to the main tower (3 meter pole) which greatly improved my reception on the R-250M. Almost no fading of signals is a nice thing I discovered right after turning it on. The height isnít that good but Iím planning to get this little thing up a few meters more. Amazing how such a little antenna can provide me excellent reception that I usually needed a 50 meter long wire for to receive similar results. :)

Yesterday I was listening to some kind of radio orchestra trough the R-250M in AM mode. (I think it came from radio Romania international) the sound was very beautiful and pleasant to listen to. No noise or interference. Just crystal clear like back in the early days :)
