It looks like a spectrogram. If it is, it's not a human voice being shown there.. and there's not really a whole lot of information that can be gained from this ("something made a sound" - that's about it).
>>768685760
looks like a spectral analysis, two status fields and a line chart
maybe some sort of radio signal?
>>768685760
could be part of a process management software

clearly it's an USB port on the PCI address 14013 bus 00

14013kHz
It is probibly a number station, the message is encrypted.
>>768685760
Short wave radio my guess. Nothing super useful. Mostly for 3rd world broadcasts and the enigmatic numbers stations. Most sound like fax machines really
>>768687463
I'm sorry, are you from reddit?
>>768687463
Numbers stations aren't encrypted dumbass.
>>768687411
This guy seems to know what it is. Don't say what the actual signal is though. Is it data/voice ? What does it sound like.
There's a great program I use called krypto500 that can "decipher" all kinds of encrypted signals, I was recently able to decode NATO Ship to Shore encrypted messages (they were still encrypted but I was able to read the ciphertext).
If you can't find it let me know and I'll upload it for you.
Also, www.sigidwiki.com will help you identify signals next time.

As posted above 20m SSB TX. Screen cap taken from WEBSDR.
>>768688484
Yes but that doesn't tell you what the signal is though. I can't tell exactly what signal it's tuned too but none of them look like USB TX's to me.
>>768688615
Either your filters massive or it could be CW. Try the CW filter option on Web SDR and zerobeat on the signal. Also check ARRL and RSGB band plans.
it’s in the morse section of the 20m band, record a clip and i’ll tell you what it is.

He didn't say it was, he said the message is.
>>768689141
i could also tune to the websdr - i’ll check it out but your filter there is wider than two separate signals. narrow the yellow marker so it only encapsulates one waterfall signal

Possible.
>>768685760
Does the audio sound like a dial up modem?
>>768689256
Ok good point, and I was totally wrong anyway because some numbers stations signals are actually encrypted, but either way it's pretty unlikely to be a numbers station, I've only picked one up once in years of listening for them, they broadcast very infrequently and always switch the frequency. All I heard was an English ladies voice spouting out numbers.
Its a morse code pileup. Lots of OPs trying to reach a rare station.
>>768690062
What's the stations callsign?
Its a loud CQ call
Dah di dah di, dah dah di dah
>>768690166
Unfortunately I don’t know morse very well at that speed. Those guys are wizard level hams
If you want to hear something spooky listen for UVB-76 on 4625 KHz AM
>>768690282
There are many programs available to decrypt/transmit in morse code.
>>768690282
I can send CQ DE and my call and copy a few letters at 8wpm but I gave up learning Morse for playing with data modes.
>>768690345
Fldigi is a good one.
>>768690345
There are even some HFFax and NAVTEX decoders for mobile devices too (literally those names on iOS) with the webSDR can actually decode them on the same device. Its absurd.
>>768685760
Can we get some context OP?
>>768689421
Been really interested in getting started with packet radio for years, but never got off my rump.
>>768690466
Same. Was always a digimode doing packet on CB (pirate) before i got my license. License is worth it for the tools you get access to, but the DX for me will always be on Sporadic-E https://youtu.be/nSKQR0k6tUY

I hear this quite a lot which is really weird to say but it’s true. If you have any sense of prepping for emergencies (to be the pro-successful robot in an emergency) then GOGOGO
Where can I listen to these online? I want to hear number stations or short wave chatter. There was a site years ago that let you stream

>>768691142
That’s classified
>>768691365
Any tips on getting started? Every time I look into it I go down the rabbit hole and just get confused. My idea was always to have a dedicated computer for this, like a Raspberry Pi or Beagleboard.
Tune to 7074 LSB and enjoy.
Its called FT-8 and you need to have NTP running on the PC to sync time with the atomic clock. Its hundreds of stations and they all show up on pskreporter.info as they exchange grid coordinates with each other and signal reports.
>>768691668
I had webrx running on my beagle one for a while. Ran like a bag of shit.
>>768691430
Thanks man>>768691430
Is this the sort of thing I can rub locally? I've seen SDR on raspberry pi using USB sticks
>>768691668
Get a standard PC as a lot of the stuff requires quite a bit of grunt for the most recent digimodes. The Pi is fine as a receiver if you only want to do receiving and decoding of actual shortwave radio- the dongles cost about $8 and the upconverter exploit the dongles originally for digital TV by RTL chipset by converting the lower frequency picked up by the antenna (shortwave) HF to input compatible with the dongle. Upconverter I have is called HamItUp. The dongle on its own will tune down to about 24Mhz so you can (assuming you have the antenna for it) listen into CB/PMR/VHF/UHF and satellite shit but the fun is in < 50Mhz
>>768692004
haha
dongle
>>768692004
There's also the direct sampling mod if handy with a soldering iron. I've had some success with mod ExtIO file too.
>>768692004
What if you wanted to run this off of a solar panel in emergency or off-the-grid situations? TX and RX. Is that just not possible unless you get a huge fucking panel?
>>768692190
Can you link to this mod?
>>768692229
I’ve actually done this- Two car batteries and 80w-worth of PV solar panels on the roof- is quite huge. Powered a RPi, dongle and it worked for emergencies but it did need topping up from the grid as the weather here is mostly shit.
>>768692190
cool I forgot about that, its worth checking into, the upconverters can be quite pricy otherwise ($40-ish)
>>768688048
>Numbers stations aren't encrypted
This is the dumbest thing I have ever heard.
>>768692396
What about antennas? I helped my daughter build a crystal radio for a school project and we were floating wire in the air with birthday balloons.

>>768692599
a wire is fine, but you'll pick up a lot of crap if its near anything electrical so ideally you want something with a feedline (coax is the most common) so your receiver only gets exposed to the wanted signals- a half sized G5RV style antenna is ideal rookie- if you have the space for it. For receive only?

I've been interested in ham radio since I used to listen to BBC shortwave on an Grundig back in the late 80s. Maybe 2018 will be the year I do something about it.
>>768693997
If your in the UK just find you local club.
>>768693713
Digital mode using phase shifted audio to subtly alter the tone pitch, its called FT-8 and is the most recent digital mode development that I am aware of. It can punch through as good as basic morse code except hundreds of operators can use the same radio frequency at the same time by having slightly different audio tone offsets

Eloquently put and noice. Those swishes look like ionospheric research signals-

>>768696208
GQRX is the usual choice. Built using GNU Radio backend bits.
>>768696328
Yeah the swishy I dunno. But the steady climbing straight line is an ionosonde for sure. A Digisonde probably.
>>768696698
It could very well be Jupiter.
Worth checking it out

>Figure 1 - idealised radio frequency spectrum of the two types of decametric radio noise bursts received from Jupiter. The short (S) bursts last only a few milliseconds and drift down in frequency with time. The long (L) bursts have durations of seconds and contain modulation lanes which can drift either up or down in frequency.
>>768698004
Can you use this stuff for amateur radio astronomy? Plug up an old satellite dish and shit?
>>768697867
Not a fan or radio astronomy (yet)
The swishy was probably an image of a higher power transmitter somewhere else in the band with frequency instability. Or someone playing with the dial while tuning up/transmitting.
>>768689221

You can point at satellites and decode data with these cheap receivers too. AERO is an information system for commercial aircraft.

>>768699447
Yeah I have a piaware setup contributing to Flightaware.com. Nice to be able to look and see what plane or helo is buzzing my house when I hear one. I've seen Air Force Two on my local map.
>>768699270
shitty conditions, loads sold up and left and 20 years later we're still in the midst of a significan dip in solar activity for maximums. means the skip went, no DX really happening and no daily listening to the people yelling back at the scottish wanker in glasgow from way across europe
>>768698924
Shit, I think my dad had one of those. CBs beat the fuck out of cell phones when you're part of a car caravan.
Back in the early 1990s I was travelling through Colorado, and all of the little mountain towns had CB radios in the gas stations. I assume the phone lines got dicey in the winter and they were far more reliable.
>>768699708
that is fucking cool

I was relatively new on the scene, around 98-00. I was too young to remember the calling channel being 14 in UK, it was strange, like cb had a mini revival with a good chunk of us school leavers, parties and shit used to get organised on cb. Must have been a fairly local thing around the East Midlands.

I was 15, nearly 16, she was 16 and went by the handle 'Kindred Spirit', tbf, she was a well known slut in local circles, but luck was on my side the day I finally met her, my mate had to look after my bike, his dog and her mate (male), while I fucked her up against a tree in a shitty little woods.

If you're referring to what we know as 'mid band' or cept, I started there but it was dead, it was only a few weeks that I realised I brought the wrong radio, I stayed on 'muppet band' after that, also I can't recall hearing you but it was yonks ago! Too bad about your loss mate. :(

Heh, small victories and that.
I'm not getting your 'warp speed' term, sorry, could you shed a little light.
Oh and not digging for info, the best thing about CB is that it was like a proto 4chan, the anonymity and that shit, haha.

thanks anon, we been through some very tough times, what i did was really cleaving myself away from my family so i could get away from the nonesense that was going on. had some very amazing experiences and plan to have a lot more of them. the only one we arent able to have is sprogs but thats always been the thing (even though i have seriously left my temple a few times about that in an existential crisis kind of way)- she helped me through the worst while i was so that says a lot.
we just never got to the point where it was feasible and now the biological clock has ticked too far for her to be safe. I end up on here shitposting stuff and answering in these weird curiosity threads (which i like to see a lot more of)
