HF con USB Dongle DVB-T ultra-barato-SDR basado en RTL2832U: http://www.youtube.com/watch?v=5y2XMvrlmiA

Los archivos ahora están disponibles en BitTorrent: http://spench.net/download/HF-SDR.torrent ¡Por favor continúa sembrando!

Para usar las grabaciones en GNU Radio, primero aplique esta solución a su fuente de archivo WAV: http://wiki.spench.net/wiki/GNU_Radio_Patches#gr_wavfile-auxi
De lo contrario, encontrará un "error de tiempo de ejecución" porque al código original no le gustan las grabaciones HDSDR.

I can not find the torrent file,i get a usrp1 recently,would you seed this file again ?Many thanks!

Hi when I run DSD with HDSdR I change my sound card to VAC1 I can decode DMR but I cannot listen to analog signals without changing the sound card setting back to the speakers how can I change this so I can hear all signals please

I enjoyed this video, thank you.

Could the large sweeping signals be coming from a doppler weather radar?

What software do you use to make recordings?

What's the widest bandwidth you can see at one time. You mention that what u r showing is 1mhz. Can it do wider scans? If so what? Thanks just found your channel and subscribed.

is it possible to use HDRSDR for files other than audio files? i want to read the signals coming from GPR (ground penetration radar) which are obviously not audio waves. how do i input such files in this software?

Where can I get the file for GNU Radio that you used for the analysis with the tabs at the top?  I love the video, sdr really fun.  I'm currrently using sdr-console and HDSDR mostly.  I've got a HAM it Up coming and plan to use it with my HackRF.

Ran across this video while researching SDR software. I have not had the opportunity to use SDR before and found this very informative. Thank You balint256. KB1ZYI

Interesting…NOT!!

Lovely vid!

Terrific job! I'll rerun to study this again.W9ZSJ

Very nice and well produced informative video! Thanks for having taken the time to share it.

How do you record "raw airwaves" like this? Wouldn't it create really big files because you need such a high sampling rate to capture a decent sized frequency range?

I will have to second the first comment, as this is by far one of the most enjoyable videos I've watched in the past year. No searching around for definitions of things, as it's already explained in the video.

This should be an archetype for a good educational youtube video.

There is an instrument which sends out a repeating swept RF signal. Signals are scattered back from the ionosphere and and also back from the ground when the signal bounces. The backscatter is measured and the distance is calculated. This way one can know where on the earth a certain signal will hit after bouncing off the ionosphere once or twice. Some people leave these devices running all the time just to annoy those of us with more serious uses of the spectrum. :p

Can someone explain to me what is a sweeper?

Very very good video. I am going to get SDR to talk to aliens

Could you do a tutorial on decoding the different signals to get the data/voice in them?

Very informative video, nice to actually learn something

the blocks that move across the spectum at a different rate seem to be in morse code staggered with a delay to either separate, or break down the message into intervals. like a binary code.

Sounds like Chase from House

Great Video! After watching this video I feel a bit…. ALL GLORY TO THE HYPNOTOAD

Very cool … sdr really looks like the way to go… just got back into scanning and ham radio… last night i was in the 5-6mhz area and found some of these.. always wondered what they might be… but i also was changing modes and switched to wide-fm and actually was able to hear a spanish broadcast in widefm that i couldnt make out in am/ssb/ or any other mode. i can't find anyone on such a signal, any thoughts?

I've been decoding digital mode transmissions since 1995 using an AEA PX232 MBX TNC. Not a whole lot good today since most RTTY/TDM/BAUDOT from commercial sites is encrypted. I now use an Alinco SR8T and SDR software for rig control but it would be very cool to have software that could do signal identification and decode the more sophisticated digital modes. Very good video.

great video! a couple of questions… how do you identify the signals? software or personal knowledge? How did you get HDSDR to display the correct frequency with the transverter?
Thanks! Just getting started in SDR and very interested… bought an EzCap after watching one of your videos.

Good morning
I I thought that the RTL2832U was tunable from 60MHz to 170MHz. I see you are in the ham band at 7MHz. How are you able to do that. I bought one of these and most of the radio waves I can see or listen to is in the FM band 88MHz to 107MHz.
Thx in advance

the sweeps are chirp transponders they go from 4hz up to 30mhz they show on a display the f1 f2 f3 layers for good propergation for tx rx ccts

This is fantastic

haha I thought those lines going diagonally were radar

I bought all needed parts for SDR just after seeing this vid 🙂
