Static or Normal?

[ButlerAlerts]

Hello,

As you see I am the owner of the Butler County, PA 911 Feed and we have static. But here is the setup.

Dell PowerEdge R210
Uniden BC355
3.5 MM to RCA then to a Ground Loop Isolator, then to a RCA to 3.5 MM
Then to a USB Sound Card that plugs into the back of the server board.

I am using an external J-Pole Antenna (With crystal-clear audio)

What causes this static? I heard it on alot of other feeds?

Could it be the scanners external speaker jack? or could it be the USB sound card causing this?

Are you using a line-in jack or Mic jack?

I have found that mic jack will amplify the noise. With that I only use line-in jacks. I also no longer use my computers sound card started using I-Mic2 and have had great results with them. All my Feeds now have them.

Also check your sound levels as they too can amplify noise if set to high. These are under Sound, recordings then properties then levels. For mine I run the computer levels at zero then turn up the levels on RadioFeed to around 35 or so depending on if it's a radio or scanner. Then I adjust the volume level on radio to so hits around half on level meter.

I checked and the volume level on your scanner is turned up way way too high for your sound card, try turning the volume down *a lot* and see if that makes the audio more intelligible.
