SimpliSafe interfering with PC audio

​Hi,​

​Since installing my SimpliSafe at the weekend I get that old fashioned buzz-buzz noise from my PC like when you held your first mobile phone too close.​

​The base station is down the hall from the PC and today I tried clipping ferrite beads to all the inbound PC cables to try and suppress it. No joy.​

​I can have my latest Android phone right by the PC and no problems. I know the SimpliSafe has a cell phone module - is it using the old cell bands?​

​Is it just me? It's starting to bug me so much I signed up to the community to post.​

​BTW - this is a UK set-up.​

​Why does SimpliSafe interfere with my PC audio?​
