Thank you for your suggestions on how to fix the interference problem I encountered while using the ELAD FDM-S2 SDR receiver with my MacBook Pro computer.
The source of the noise seemed to be the computer's battery charger/power supply, but all my attempts to fix the problem failed until I noticed that my Heath coaxial switch was not grounded. I assume its connection to ground had been disconnected while I was rearranging the furniture and I forgot to reconnect it.
Reconnecting the switch to ground made a big difference and eliminated most of the noise on the AM/MW band.
