Comment on Displaying Live Weather and Traffic Data from HD Radio (NRSC-5) Signals by KYDronePilot

Sounds like you’re using the program over SSH or on a computer with no desktop. This program uses a GUI, so you’ll have to have a desktop running on your machine when you start the script.

If you have any more questions, open an issue on the GitHub page.

User Projects • Re: Newbie question on demodulation

Thanks for the reply. I am familiar with GNU radio. I was thinking that there may be open source libraries for demodulating standard BPSK, OQPSK, etc. with the RTL-SDR and librtlsdr.

Thanks,
Y

Signal Identification Help • Re: UHF Military Wide-Band Signal Identification

Ah, I see. I'm in Dublin Ireland and the DAB frequencies are located around this frequency location. I didn't realise it could be a DAB block. Thanks for the help.

Help using DSD+ with SDR# and decoding P25

Hello all,

I recently purchased this SDR. It is setup, and I am able to use it to listen to FM broadcast to verify it is working. I am having issues hearing anything on DSD+ when piped into it. Any insight on what my issue is?

Setup:

  • V-Dipole antenna from kit > LNA > SDR
  • SDR#
  • VB-Cable
  • DSD+ with DSD Interface Plugin for SDR#

Configuration:

  • SDR gain = ~38 dB
  • SDR# audio out = [Windows Direct Sound] CABLE Input(VB-Audio Virtual Cable)
  • DSD Interface Audio Device = [Windows Direct Sound] CABLE Input(VB-Audio Virtual Cable)
  • DSD+ initialization showing audio I/O

Procedure:

  • Plug in LNA and SDR
  • Start SDR# and tune to channel
  • Ensure audio output correct
  • Click "Play" on SDR#
  • In DSD Interface, click "Start DSD

Output:

DSD+ outputs and SDR#

and I don't hear a thing. Am I missing something? I am very new to this, so and insight is greatly appreciated.

Beautiful – but it all makes no sense unless we get any idea if, when or where we can get it.

the USB ports are in the Ryzen chip, not the southbridge.. Thus WIn 7 does not support them..
Ryzen chip set needs win10 for full functionality.

Signal Identification Help • Mystery ‘drifting’ signal

I was looking around the Air band at approx 132MHz on my SDR, and came across this mystery signal. It's constantly changing frequency, then every 1.5 seconds jumps to another frequency making it impossible to tune in clearly. I'm wondering if it's some kind of scrambled transmission or perhaps something not broadcasting correctly?
