Hello guys, um, what the fuck is this? I don't know what

>>1216505
Thats a post WW2 Seismometer

airplane part prolly

>>1216505

clueless as well,

Looks like a old maybe not military but precision high grade radio.

>>1216505
this is a replica model of the device that Charles Richter built to scale earthquakes

>>1216514
that I can tell you, it is not. see those 2 white white knobs? they go to a pair of headphones. It's some kind of radio i thought?

>>1216514
It's seismic refraction equipment, call a civil engineering school and they'll buy it for historical value, ask $5k.

>>1216543
got any idea on how you'd operate one of those?

>>1216551
Newer ones have microphones that you would stake in ground in a line, bang on a sledgehammer to make a wave. Said wave bounces of shallow rock and detected at microphones giving depth of rock. This old one probably only has one mic and a sensitivity setting for fraction second timer.

okay, I'm back. I opened it up today, pic related. I asked my mother if she knows about it, she told me that my father used it as a radio transmitter for morse code. which explains the fact that I found one of those things you use to "type" morse. And that the whole thing has headphones attached. It still works and if it is a radio, well I belive that it needs an antenna.

Post it on an amateur radio site. Then see what it's worth on Ebay.

>>1217064
But I don't want to sell it, maybe I can use it somehow

>>1217047
Its a military hf transceiver plus psu, looks like it covers some ham bands. These things can be a bastard to identify, but id guess Frence. Does it have any more identification details on the back? Ham fag here btw

>>1218952
Well there are tags on the front and they are in Romanian. Also it's from the Communist era, so it's most likely a Romanian radio. But I'm not currently home, so I can't take more pics.

>>1218952
I know for a fact I need to build an antenna for it, but I don't know how

>>1219203
Go with a simple dipole antenna to begin with. Take two 10.5m lengths of wire and connect one to the center and one to the shield of some 50ohm coax, hang both elements horizontally.

>>1219208
I am sorry to let you know but, that radio doesn't have a coax plug, it's just two wires hanging out. Or that's what I think that cable is. Most likely.

Looks interesting! I've been trying to cross reference the corporate "EM" insignia on the builders plate but so far no joy. Do you have a pic of the back and inside-top of both units? Strange mixture of english & cyrillic, I wonder if the english knobs were a user modification? The main tuning knob looks too small as you can see the two stop posts that keep the knob from turning a full circle. Anyways, i'm thinking this may be a Polish built unit (no "R" in russian cyrillic which appears on an internal component) built between the late 50s and late 60s? My interpretation with the limited info is such:

Definitely european due to Stas power plug.

A: Crystals plug into one of the 5 sockets which may correlate with the 4 bands on the main tuning dial. This external module may act as a type of external VFO?

B: You describe a morse code key. Is that what's plugged into here? Headphones may plug into the socket below it.

C: 5 position band selector. (four bands, plus direct from crystal?)

D: Location where crystal frequency + settings written on a piece of cardstock for quick reference.

The main tuning dial has me stumped, I thought it covered 0 to 45 MHz but the graduated scale says otherwise. The left of the band has "x 10" which means take the number on the dial and multiply by 10 & you would need the frequency of the crystal you are using too. Very confusing to figure out with just a picture.

In the 2nd pic you can see the frequency ranges of the 4 bands. It looks like 87 Hz, 2500 Hz, 7000 Hz, & 5000 hz but I could be way off base on that.

I'd be surprised if it still works as it should. The capacitors would be my 1st concern. Any back info on this unit? Approx where its located, when your Dad got it, & what time of the day he usually used it? Was he a ham?

I know it's confusing, I'm going to get home by tonight, hopefully I will be able to provide more pics. There's no Cyrillic on it, although another Romanian Anon from a thread did provide me with some more information about it. It's a Romanian production, and my guess is that it's a copy of the us-1 from 1945. All I got was some pictures from a museum though. Yes he was a ham, back in the day, my guess is pre 1989. I am not aware of any crystals, the only things I have are those little knobs that screw in and out of it. Power does run through it, so it's fully functional. It lacks an antenna, but I'm going to make a simple wire one for testing purposes.
On the a side, right below every hole, if I recall correctly, there is a number, my guess is some sort of voltage? 110v.
In the b socket I had plugged the original headphones. The Morse code key does not have the connector pins, they're bare wire.
I think? Don't quote me on this but I think it covers a frequency between 0.127 MHz to 17? Pic is the thing I found in the museum. I thought about shooting them an email maybe they could give me a photo of that cardstock. Or any more references.

it's still not working. or, at least, not working as it's supposed to? to be honest I don't even know what "working" is supposed to be. although I do remember making a totally different noise .

Here's a vid of the turning on https://youtu.be/Iy9Tt_KpidY

and here's a pic of the back of it, aka where I should mount an antenna but im too retarded to do so. sorry for the mess btw.

>>1220058

I was actually being serious. This OP is pretty cool, unlike a lot of others. The "shitty meme?" It was an afterthought, a joke. You know where you are, right?

>>1220076
sorry, did not intend to sound like a dick. people kept meme-ing the shit out of that yesterday and I thought you're here trolling. Why thank you, I am flattered.

>>1220058
>>1219845 here, very neat! 1940s tech... I somehow missed your earlier mention of a Romanian origin. I would e-mail that museum & see if they can offer more info or a users manual. Usenet used to be great for this back in the day, I miss it. I've read that Romania used to be the Euro version of China, they'd steal & copy designs to everything.

I watched the youtube vid, just an AC power hum unfortunately. Those tubes usually need several minutes to warm up & they drift in frequency for a while until the temps stabilize. Get an antenna up (a simple alligator clip attached to a clothesline or raingutter/downspout) the audio should be like static or white noise. Try tuning around the AM band, if working properly you should hear the high pitched whine of the carrier frequencies of the AM stations.

If still nothing, further troubleshooting will be necessary. Due to it's age it's quite possible that the tubes are "flat" & will need to be replaced. The power supply could be shot. Other components may have dried out over time too so their electrical values may have changed or component completely failed.. Then you're getting into the realm of repairs/restoration which will be a bit daunting.

Possibly from one of the ex-yugo countries.

>>1221241
it's not yugo, and there's no cyrilic. it's all romanian. I would appreciate some ideas for an antenna though

>>1220058
Than instant mains hum is bothering. Wondering if there is a short going on. Typically valve sets take 5 to 10 seconds to get up to working temp. I'd start by pulling the rectifier and measuring transformer output voltages. Take care because 400 volts is not uncommon in those.

If you have no idea find someone into historic radios, old hams or tv guys etc

>>1221237
>not having a porn switch next to your toilet gun
shameful desu

>>1220476
(sorry for the reply delay, work shifts just changed)

I'm not sure what i'm looking at. Basically one wire is the antenna, a 2nd wire goes to ground. On your radio I don't know which ones that is.

If you are running a random length long wire as an antenna the grounding wire could be connected to a copper water pipe in the house (if convenient) or onto a ground rod pounded into the ground.

But the ground wire isn't critical if you're just trying to see if the receiver is functioning. For 2 years I had my shortwave radio clipped onto the rain downspout going by my 2nd floor apartment just to receive. No ground used.

With your radio powered up for a minimum of 15 mins, take your antenna wire and attach it to one of those wires. If you don't get a static/white noise sound like you would on an AM radio tuned between stations, I would suspect an internal fault.
>troubleshooting old foreign radio
Thennnnnnnnn the fun begins. :-/

>>1220476
Ach! I forgot to ask, looking at your pic is that red wire with the two conductors you have labelled "1" & "2" the antenna? If so do not connect the two together, it will just short out the signal.

If you get nothing, try reversing the antenna connection.

>>1221278
>>1221629 >>1221631 here again.
The common method would be to string up a 1/4 wavelength dipole up as high as you can. The higher the better. Look at "inverted V" designs too.

Because your radio tops out at 17 MHz (irc) a quarter wavelength is around 15 ft. But the lower frequencies get longer. You will still receive but with less efficiency.

My very 1st SW radio was Panasonic RF2200 loaned to me in 1981 when I was 13. I hung up a single conductor stranded wire around the edge of my bedroom ceiling. Essentially a square loop but the end isn't connected to anything (except the one end connected to the radio of course). Luckily the shut off valve for an outside garden faucet was in my room so I attached a ground wire to that with a hose clamp.

Seemed to recall it working for me. Half the hobby is about antenna experimentation so try different things.

Unless another ex Soviet spy is still out there sending morse code you are unlikely to hear anything.

Plus, I have seen the old valves before on movies, you need to pull them out of the board and blow on the contacts before pushing them back in.

>>1221637
i have an old tv antenna. would hooking up a coax cable in the antenna then hook he wire with the radio and then grounding it work?

>>1221670
Just connect the whole coax outer section to antenna terminal. But first do this. If the buzzing goes sway
or reduces substantually with the rectifier removed you have to fix that issue first. Failure to do so may result in a burnt out mains transformer which is not easy to come by.>>1221285

>>1216505 This is only reciever from air-bomber. Now it,s unuseful.

>>1222085
You can't break down it through wrong antenna connection. But what will you hear in range 175kHz-12MHz?

>>1221670
using tv antenna or tv cable is unefficient for this range. You should use long single wire ( from 6.25 to 400 meters - 1/4wavelenght) Aluminium box should be grounded.

>>1222093
In your video antenna isn't connected to antenna terminal in right bottom korner (with letter "A"). И вooбщe нeпoнятнo, чтo тaм зa пyк пpoвoдoв тopчит cзaди из кopпyca. And earphones connected wrong.

A - PSU - I din't find any descriptions in user manual. Likely your reciever station was finalized for indoor use.

C - range selector 1 to 5 range.
Ranges 3 to 5 are drawn on the adjustment scale. Numbers are wavelenghts in decade of meters. You hould multiple number from scale by 10. Now on the picture reciever is set to range 4 and ~14,5*10=145 meters.
For transform it to frequency you need to divide 300000000 m into 145 m = 2,069 MHz

D - Here was table for 1-st and 2-nd ranges. As You see step of wavelenghts from 5 to 3 is smaller and smaller. And table was for smallest step in 1. and 2. range.

>>1222478
And manual volume control is on the left of antenna connector.
So, I describe all control points and you can try tune into some radiostation. or not :)
