Now, being a gadget lover that I’m, I made a decision to improve the moderately previous dashcam in my automobile to one thing somewhat extra “HD”. After doing a little bit of analysis, and seeing the footage of a colleagues digital camera, I made a decision to get a Mobius 1080P Actioncam, bought from a good supply (beware the fakes). Good selection. Small unit, nice photos, sound is OK… besides….
… it ruined my radio reception.
Now I’ve a newish automobile, and it is fitted with a DAB radio. After becoming the digital camera to my windscreen, I observed DAB reception of my favorite station, Planet Rock, grew to become patchy. Disconnecting the digital camera solved the problem…. hmmmm … RFI … Radio Frequency Interference.
So what was occurring? I broke out my historical spectrum analyser, and, geared up with a easy whip antenna, took some measurements….
… and here is the identical shot with the digital camera linked… yuck. I think the massive peak to the correct of the mux is effecting the AGC of the radio, and there is quite a lot of hash beneath it too, upsetting the sign to noise ratio… boo!
… and after some subject assessments, reception restored!
