I hope this is the right place to post... I searched the forums and found RFI posts all over the place! Unfortunately none of them seemed to cover 5VDC gadgets.
I have a Chinese dash cam (I think it's the i1000 as seen on dashcamtalk) which seems to be emitting interference. Does anyone know if it's possible to shield the device to eliminate it?
I was pretty happy with the camera until I got into amateur radio. I also have a Uniden BCT15X and a Baofeng UV-5R. Ordinarily, the camera is running whenever the car is on, so I didn't notice the difference for a while... One day, I happened to turn it off, and suddenly the HT and scanner lit up, signal coming through. I played with it a bit... as soon as it powered up, a strong signal got choppy and noisy, and weak signals were squelched out. Tried unplugging it, thinking it might be the power supply, but it's even worse when running off the battery (perhaps the power cable is grounding some of it out?).
Again, I'm picking up the interference on both a plugged-in mobile scanner and a battery-powered HT. My first thought was ferrite beads on the camera's power cord, but it wouldn't help much if I can pick it up on a battery-powered HT, would it? What about a pseudo-Faraday cage? Wrap everything but the lens in foil and try to find a place to ground it? Does that actually work?
Is there anything I can do besides ditching the camera?
