DAB Radio in car
My DAB has been breaking up recently and the radio automatically drops to
FM. This is a bit annoying though die to the slight time difference. Grubbing about on a Facebook Group someone asked if I had anything plugged into my Cigar Lighter Socket - I have - a Dashcam. I unplugged it and the problem went away. It seems the 12v to 5v ciruit causes interference. I found a couple of YouTube videos that seem to confirm it. Now I need a solution! https://youtu.be/O2npY4BApZM?t=211 |

Cheap chinese rubbish again. People on here have sneered at me about
worrying about these voltage converters, saying who uses radios these days, well... My suggestion is a ferrit ring on the two sides of the circuit, but if its built into one of the units it depends where its getting into the system, if its through the electrics, than a choke and capacitor might sort it, but if its radiating from the power cable to the dab aerial then apart from the ferrite bead idea, I'm at a loss, You don't get such problems with the less efficient series regulators as they are analogue. Of course it could be some interference from the camera electronics, but that is less likely. Brian -- ----- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

Well in that case it has to be the camera itself then. Maybe it has also got
some kind of inverter in it as well. Try the ferrite bead idea, also move the camera about and its lead, perhaps the dab aerial is close to where its living at the moment.

Doesn't really help in tracking down the source of the problem as you've changed more than one thing. -- Cheers Dave. |

UNBELIEVABLE: It's 09:37 am in Australia and the Senile Ozzietard has been out of Bed and TROLLING for NINE HOURS already!!!! LOL

Speed, the auto-contradicting senile sociopath, blabbered, again: FLUSH the clinically insane senile asshole's latest troll**** So you've been up and trolling sinc 00:47 (your first post) ALL NIGHT and ALL DAY long! Yet AGAIN! And you do it almost EVERY NIGHT now! Looks like I'm having quite an impact on my sleepless senile punching bag!

Replace it with an (inefficient) linear regulator, such as some variant of a 7805, with a heatsink, instead of the (efficient, but noisy) switched mode supply that you have? SteveW |

SteveW You can buy better converters too. The ones for RC model planes are - surprise surprise - specced for low RF interference.
