Hum/Buzz in audio feed

[turboglenn]

I just started a feed from my house and have noticed there's a baseline hum to the audio which when there's voice traffic isn't an issue but can be a bit annoying. I've heard this hum on feeds I listened to in the past before becoming a provider, but am unsure what's causing it.

I'm broadcasting from a uniden home patrol 1 and it seems I can lower the hum by lowering the level on the "line in" properties on my PC, but didn't know if this might be a result of a poor audio cable or if there's a certain amount of volume from the scanner as well as a certain amount of level gain on the PC side that's optimum for reducing this. Any advice is appreciated,

Thanks

A hum in a feed is most often caused by a ground loop. Could be a power supply, or your PC. Most times this is solved by getting a "Ground Loop Isolator". They can be found on ScannerMaster for about $22. Isolator Cable Male To Male

Hey, thanks for the quick response, guess I've got something to look into come next payday. Again, thank you

well, looks like you were correct, I pulled the wal wart and ran the scanner off battery alone and the hum is gone completely. Looks like a ground loop isolator is in my future..

thanks again for the help

I just went to the audio settings in my computer under microphone, clicked the enhancements tabs and enabled "noise suppresion".....that fixed it for me!

switched my input from "line in" to microphone and enabled suppression as you suggested and mine is also fine!! thanks for saving me 20 bucks!!

Glad I could help and save! Im not sure what the difference is between line in and microphone but mine has worked good on microphone for ever. Keep scanner volume to a minimum and input volume to 100%. Enjoy
