OT (a little) DAB radios and battery life
Listening to Radio 4 this morning they did an item on (I think) Norway
and their switch to Digital radio - it appears that by the end of 2017 FM radio switch off in that country will be complete. Anyway the bloke said that approximately 48% of UK radio listening was now digital and when this reaches 50% a date will be set for UK FM switch off. When DAB first came out it was reported that all sets consumed batteries like it was going out of fashion and as they all used basically the same chip they were all as bad as one another. I have an FM radio that sits in the bathroom and gets used for about 30 mins a day. 4 rechargeable C cells last about 3 months or thereabouts. Direct connection to the mains is not an option. Has the design of DAB radios moved on such that it is now possible to get acceptable performance from disposable or rechargeable C/D batteries. I'm not keen on bespoke rechargeable as the replacement cost (even if available in 5/10/15 years time) will doubtless be astronomic. -- Chris B (News) |

There's bespoke rechargeable, as in a wierd battery pack that fits in the C/D slot, and bespoke as in a lithium battery that fits inside. Those can be a bog standard 3-wire lithium pouch cell - find one about the right size and you're done. That kind of radio can charge from a phone charger, so it makes charging less of a hassle. I'm thinking of things like this: https://www.sony.co.uk/electronics/dab-radios/xdr-p1dbp (15-20 hours battery life) which have a battery pack that looks like this: http://www.ebay.co.uk/itm/Rechargeab...-/182382582414 A lot of the DAB radios are stuck in 1960s as regards their battery arrangements, not just their styling.

I'm not keen on bespoke rechargeable as the replacement cost (even if available in 5/10/15 years time) will doubtless be astronomic. No, not really. I have a DAB radio that takes 6 AA cells, and draws 120-200 mA, both in FM and DAB modes. (120 mA with the volume at min, 200 at max. volume). This means roughly 10 hours of listening, using eneloop rechargeables. This is not acceptable for shed use, far from mains for recharging. This compares poorly to an old 80's Walkman with an FM-only radio, that does about 6-10 hours on two used AA cells, used as in "too weak for the GPS to use". (Its reception is poor, requiring fiddling with the speaker wire and careful positioning, and also has a fiddly tuning knob.) A post asking about a less power-hungry DAB+ radio in appropriate German newsgroups came up with exactly nothing. Thomas Prufer |

Not that much. I see still some sets use rechargeable and this has to be for
this reason. Besides, from one manufacturer, recently I heard that usage of digital has to be over 75 percent before fm will be turned off. Many of the commercial stations cannot afford the current rates to broadcast on dab in stereo, and test are still under way with dab plus and many radios cannot get that at all, including most of the older Pure range and some of the german fitted car radios. Also nobody has come up yet with a version of the s tuning knob so blind and elderly folk can use the current radios without help as there is no actual knob just buttons. I think though that when they do switch of, if ever they do it will be a pirates bonanza. Here in London its already chock full of pirate fm stations with islamic spoutings, bible bashers, drug funded rave stations etc, all concreted into the tops of tower blocks fed from band 1 low power t transmitters beamed to them from other parts of the city.

DAB is at a somewhat higher VHF band III ~ 200MHz so about half the FM whip length is needed. SHMBO has an awful Pure DAB radio in the kitchen and has to extend and adjust the telescopic aerial constantly to hear any music amongst the squawking choppiness of the output. That is normal for DAB. You can make a dedicated aerial for it from some coax (simplest type) or a dipole loop which will improve things a bit but it still dissolves into boiling mud when it rains. In the spirit of DIY. This describes the simplest method that works OK http://motorhomefun.co.uk/forum/thre...antenna.34914/ Still only as good as the broadcast bitrate though -- Regards, Martin Brown |

I'm a radio head and to the annoyance of others must always have the latest radio. although a bit expensive a Roberts Internet Radio Stream 93i consistantly gets the best reviews. its not portable though. But roberts now have a small portable stream 107. it does FM, DAB and internet stations (in excess of 20,000 stations world wide to choose from). we have 'swiss classique' playing all day. all good classical music and no talking. it runs off 6 AA batteries which you can conveniently charge in situ. no i dont have a connection with the company. |

I still cannot get a reliable DAB signal downstairs, only upstairs in the rooms facing North. Listening to DAB is the radio equivalent of all those nasty synthetic visual artefacts that seem to be part of 4K tv's. |

OT (a little) DAB radios and battery life

That is normal for DAB. You can make a dedicated aerial for it from some coax (simplest type) or a dipole loop which will improve things a bit but it still dissolves into boiling mud when it rains. Except when it doesn't. If you have some signal then it should make an obvious improvement. But doubling "no signal" is still "no signal". Parts of the A1 for instance. -- Regards, Martin Brown |

In message , RJH writes I have 2 table top DAB radios that run on batteries: http://amzn.eu/5mECL37 http://amzn.eu/8UHF20O (Bought them both from Sainsburys. They seem to be quite regularly discounted to £40ish. I prefer the sound/build/use of the Sony) I think they both advise against rechargeable batteries in the instructions, but they both run fine. About 2 months I'd guess, used maybe 20 minutes each day, using Aldi rechargeable C batteries. Probably a stupid question, but I see that the Panasonic one's description says "Whip aerial (FM)". Does this mean that it/they have some sort of internal aerial for DAB? Not so far as I know - FM and DAB share the telescopic aerial. SHMBO has an awful Pure DAB radio in the kitchen and has to extend and adjust the telescopic aerial constantly to hear any music amongst the squawking choppiness of the output. I suppose it's luck of the drawer/postcode. Both work here (Sheffield) with a full signal without unfolding the aerial at all. -- Cheers, Rob |

One where you couldn't just use the delay to tell which is which. The fact that in boiling mud the announcers frequently sound like the Aquaphibians off Stingray (even with a decent areal) and the absence of signal on parts of the A1 not that far outside London for starters. As I said before no transmission system is perfect. As you've probably noticed with your mobile phone - which has a far larger budget for transmitters. Yet will still have plenty blind spots around the country. -- *A conclusion is the place where you got tired of thinking * Dave Plowman London SW To e-mail, change noise into sound. |

Smart phone and bluetooth to the in car system - it might cost you if you don't have all you can eat data but for audio streaming it gives a fair amount of listening time. You complain about poor DAB reception on the move - but think a phone is going to be better?
