• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    Need help: Can't Get Good Audio on DSD +

    A newbie could really use some advice from a wiser forum member here. Apologies if this post is miscategorized. I believe this is a decoding issue, but the root cause actually may be a misconfiguration in Unitruker. Getting noise, and faint voice in the background. I got it to work once but...

    Hi all, I have a successfully configured DSD+ install using a RTL2832u + R820T SDR stick. All other systems decode successfully when I have a strong enough signal, but not this one. The problem is not with noise, as the signal is way above the floor. Based on my experience, it sounds like a...
