RTL-SDR Discussion • Hot all the time

I just got my dongle a few days ago. Is it normal for it to be hot any time it's plugged in? (rtl-sdr v3,Mac,CubicSDR) I was expecting it to cool down if the it was stoped or CubicSDR was not running.

SigID digital voice

Hi, I have just found something new in the spectrum, what I could not find in the SigID WIKI, can you please try to identify this? I had it tuned for about 5 minutes, then I started recording, after a while the signal slightly changed like some transmission has started (probably voice). Also the frequency does not match the step here, which is 12.5kHz here in the Czech Republic. Screenshot: https://puu.sh/x0IM2/6f486f4807.png Recording (28.7MB WAV, right click, save-as): https://puu.sh/x0IOU/d59c4e9b42.wav

Thank you!

Nexus 5x w/ USB-C OTG?

On the list of problems I've been ignoring for a while, when I switched to a Nexus 5x, my RTL-SDR v3 dongle and SDRTouch combo failed to make the jump to USB-C. Having the "official" Google store USB-C OTG-ish adapter, the SDRTouch driver doesn't appear to see the dongle and I get stopped dead in my tracks.

The USB port is obviously occupied so I can't easily adb shell in to debug. Does anyone have this combination of hardware working?

Hi, great instructions. I have a USB TV DVB-T 210 v2.0 from AugustInt. It works fine as a TV receiver with their driver and software

I wanted to see if it would works a s radio receiver too
However when I install the driver using zadig – I only see a devive called usbstick
I had removed the windows drivers and also removed the device in windows before starting

Zadig installs the new drivers ok – I get the success message
However when starting sdrsharp – and selecting RTL-SDR (USB) I get a message – no device selected

Is this because my existing dongle is not compatible ?

thanks a lot, very clear instructions and working links too

Are you sure that your using an upconverter and not direct sampling mode? Can you send a link to the exact model that you bought? I'm a bit convfused as you say that its using an upconverter, but you are using direct sampling.


Oh, I thought that I was using an upconverter but I use direct sampling to hear hf, you can see the model on the link in the main post, I post some pictures of the pcb here too, but I thought I was using an upconverter... I couldn't be more wrong I guess.

Comment on A Homebrew One Transistor Upconverter for the RTL-SDR by John Mills

Thanks for the comments, you have given me some ideas with your design, I’m going to try an SBL-1 with a 100MHx DIL Osc I have and see what happens, I hope I can find an SBL1-1-X in my spares box which operates to 100KHz.
