DAB Signal
#1
Hi all, I have a 16 plate B9, fitted with OEM touch screen/DAB radio. 

Is there a way to improve the DAB reception?

The radio tends to frequently loose the signal. Where my old car was great . 

Thanks in advance [Image: LIKE.png]

I cant help with anything specific but I know others on the forum have put better dab aerials on, you could try a search and see if the posts come up.
Are we there yet????? Huh

Having spent 4 hours googling. there are a few mentions of the possibility of a dash cam power lead interfering with DAB reception.

As It happens I have a  dash cam. I will disconnect mine tomorrow and see if there is any improvement.

If there is the answer may be to put ferrite rings on the power lead or re-route the cable. 

Will update this tomorrow.

I had the problem with my dash cam interfering with the signal on my old B9 - the DAB unit on my current K9 isn't the best either but there is one simple fix you can do to improve it.

Buy the longest aerial you can find - the short stubby one fitted by Citroen is useless! £9 from Halfords sorted mine out a treat, i now only get the odd blind spot with signal and that is only on certain frequencies. This isn't a specific DAB aerial, just a normal screw on unit as per whats on the roof currently.

One other thing i did find was an issue was the aerial base - they had a tendency to pack in but they cost about £25 from the dealers and take 30 mins to swap over and can make a world of difference.

Today, I drove my Multy around a short route where I always loose the signal. i wen around twice to confirm the dead spots for my radio.

I unplugged the power to my dash cam and repeated the drive. The dab was perfect showing a good signal strength for 100% of the drive. Next step purchase ferrite chokes and fit them.

I will update again when completed.

Fitted ferrite choke and improved reception by 99%. Just the odd split second drop out. But well happy. https://www.youtube.com/watch?v=DDEXBgx3ol0

It's only pennies to find out. My power lead is 4mm and I purchased 3mm ferrite chokes and it was a very tight fit. I should have purchased 3.5mm. The are more vids on youtube.. It has made a big difference to my setup.
