• 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.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

    Antenna Radials

    What would be some cons to using 1 ground radial instead the standard 4. If 1 ground radials works perfect, why would I need to use 4? This will be on a VHF antenna

    Need help with Ground Loop Isolator

    I purchased a ground loop isolator from Scannermaster (Isolator Cable Male To Male) to try and help with a hum and general background noise on my feed. However, when I plug it in, it silences the feed completely. Even if I turn all my volume levels all the way up, you can barely hear anything...

    So I have scanned Dallas/Ft. Worth for several years but for some reason I have missed the Dallas Fire frequency that is listed as "Repeated Fireground/Admin" at 453.67500 with a tone of 131DPL. I am guessing I have missed this because it is never used but I was curious to know if anyone has...
