Terrible DAB reception

Throughout this week I have not been able to listen to DAB on my Onkyo 515 DAB.  I use it via my television aerial and usually the reception is about as good as it gets.  This week all I have heard over DAB are pops, dribbles and what sounds like someone suffering from acute intestinal problems surrounded by acute distortion.  It has been utterly useless.  Fortunately I can, of course, connect via the internet, but even that hasn't sounded that great.  What seems incredible is that reception has been fine when listened to on my cheap old analogue portable radio on FM.  I live within 60 miles of London.  Has anyone else had these problems this week, or is it just me? Has the BBC reduced the power of its DAB transmissions for some reason?

Re: Terrible DAB reception

Not an uncommon experience on DAB, I'm afraid. I live 12 miles from central London, yet DAB reception is patchy at best.

Y'see, that's where you're going wrong: using a TV aerial for DAB isn't ideal, and what with all the TV digital switchover malarkey going on at the moment, almost anything could be affecting it.

Re: Terrible DAB reception

Quite right, DAB or (Diabolical Audio Broadcasting) works in the 200MHz region whilst your TV will be in the order of 800MHz or thereabouts, you will have little signal on the antenna getting to your tuner.


Get a proper DAB Aerial and then you can enjoy all the faults of DAB perfectly! Wink

Re: Terrible DAB reception

People would not dream of using an FM or DAB aerial for their television reception, but when it comes to radio (whatever it is ) anything will do!

If you are not prepared (or able) to get an optimised DAB aerial professionally installed on the roof then maybe you could use Freeview radio from your TV (or Freeview box or whatever) and connect with an RCA phono lead to a spare input on the back of your Onkyo.

Re: Terrible DAB reception

Thanks for the replies, guys.  Yes, I know that I'm not using the right aerial, but DAB usually works just fine for me and my purposes via a digital aerial.  And yes, I know bad reception is not that much of a fag as I have the internet and freeview.  However, what I was asking was whether anyone else had experienced poor DAB reception this week, and what causes these periods of poor reception on DAB - whether it's the high pressure weather system or a change in transmission or signal strength.

Re: Terrible DAB reception

I have used the BBC transmitter work/reception problems tool for a random Romsey SO51 postcode and there are no problems or scheduled work for all three of the transmitters that serve your area. 

(I assume you live in Romsey from your name.)

Re: Terrible DAB reception

Thanks for the interest and help, Chebby.  I will wait a while and hope for improvement, as reception has been patchy in the past and then improved for no apparent reason.  As I have said, it's usually very good and clear here.  The tool you use sounds very useful.  Is it something I could get from the internet?

Re: Terrible DAB reception

Don't forget that you either have a DAB signal or you don't.  There isn't any kind of in-between mush that you get with FM if the signal is weak.  I imagine that you were previously listening without interruption although the signal was only just strong enough.  It has only taken a slight reduction in strength to make the sound disappear completely.

Re: Terrible DAB reception

Its not quite signal or no signal.. The audio starts burbling before going silent. I was using an indoor aerial and I noticed the quality changed when people moved around the room. Thinking about getting an external aerial now. Just got to get around to it.

Re: Terrible DAB reception

I have exactly the same problem with borderline DAB signal quality. Signal goes from just about OK then to as though someones torturing an acoustic guitar before dropping out completely. Must be to do with where we live because Freeview signal is also borderline with frequent signal dropout.

You are not alone- for about the past 2 weeks,there has been intermittent but significant variation in signal strength and mine is currently on the TV aerial pending roof work which will enable a proper DAB aerial- but it has gone from strength 180-220 on radio 2 to virtually nothing at times(yes no signal is better than some for radio 2).Since it is on the end of a booster I unplug the main TV socket in another room which helps but does not cure.


As Andrew says ,TV signals are doing all sorts- the above has coincided with receiving repeated unwanted TV notifications about the switchover/analogue switch off.

Re: Terrible DAB reception

I live about a mile from the Crystal Palace transmitter, but I installed a proper DAB aerial in my loft.


Even in good reception areas such as mine it is always worth doing the job properly.

Re: Terrible DAB reception

Well, after a few weeks of behaving itself reception has gone again today.  Methinks it is to do with the high pressure weather system, since reception always seems to take a hit when the barometer's up.  However, clearly I need to do something about this problem, but what?  One route would be to get a proper aerial, which I understand can be spliced into the TV cable.  The other route is to wait for the BBCs online radio portal due in December and ditch DAB.  I could then trade in my little Onkyo for separate amp and CD player.  

Any thoughts about what route to go down for the best and most convenient results gratefully received.

Re: Terrible DAB reception

Why would you want to splice it into the TV cable?


Do the job properly and use a seperate cable. You will not regret it.
