We utilize VHF, TX/RX base radios in our office facility. I have an external speaker system attached to my PC. It has an amplifier.
When someone transmits from the office radio, a loud buzz comes through the PC speakers. It does not buzz when the amplifier is off.
So somehow the amplifier is picking up the TX signal.
Does anyone have an idea on what kind of filter I need to attach to the amplifier to filter out the TX frequencies?
Thanks!
