Picked up RF interference from a neighbor's baby monitor during a test run

I was testing a homemade audio bug I put together last weekend, hiding it in a clock radio in my garage. Everything worked fine until I walked outside and my receiver started picking up this crackly baby crying sound mixed with my own test tones. Turns out my shielding was garbage and the cheap coax cable I used was acting like an antenna for the neighbor's monitor 3 houses down. Has anyone else had luck with ferrite beads or better shielding for keeping out external noise?

Wait, you used cheap coax for this? Oh honey no. That's like trying to bake a cake with salt instead of sugar and hoping it still turns out sweet (the wrong ingredient for the job, you know?). Ferrite beads will definitely help clamp down on that noise, but honestly your first move should be swapping that coax for something with proper braided shielding. It makes a huge difference.

Sounds like you built a baby monitor, not a bug.

Did you actually test it in a real room with walls or just on a bench with line of sight lmao?
