DAB radio model Sharp FV-DB1E

Not tuning properly after being switched OFF at mains ( not on battery operation). I receive the Inverness area DAB package of normally 23 stations ( 12BBC and 11 commercial ) BUT when I did the Autotune Full operation as I have always done only 15 stations tuned in ( 12BBC and only ' heat ' and the 2 local ones of Moray Firth ) No Classic., Talk Sport or any of the other national stations always on DAB!!!!
What is the problem ??? Signal quality reads in the 90s and Signal strength shows mainly 8 bars which I feel should be more than adequate to tune ALL the available stations!!!
Will I have to Reset somehow my beloved Sharp DAB radio which has not given trouble over the last 2-3 yrs since I was given it as a b'day present?
Help, Help, Help - my dear wife is falling apart not being able to hear CLASSIC FM her favorite radio station apart from Premier( which is not on DAB here yet).
Colin the troubled husband!!!

    I have experienced the same tuning problems as swannerX's - playing with aerial orientation plus shortening aerial to about 300mm has worked. I use mine on mains only but the two 'AA' batteries charge level seem important to station tuning. I use rechargeable 'AA' batteries and get tuning problems when charge levels are low. Switch your set off at mains for 1-2 mins and install new 'AA batteries with over 2000 mAh rating and then try run full tune.



    I agree that this Sharp FV-DB1E is sensitive to good reception - I'm in West Yorkshire and Radio 2 is sometimes better on FM than DAB, Ive assumed this to be atmosphere conditions. I get a healthy 32 stations including two test ones and the bird song. Virgin has just changed to Absolute now.

This is SwannerX and I have solved the problem by locating the DAB radio receiver to a higher position ( some 6ins. higher only ) and orienteering the aerial in an opposite direction.
All 25 stations now tune O.K. and signal quality still reads in the high 90's and signal strength shows 9-10 bars. This is not substantially any more , but it has done the trick!!!
I am still very puzzled why it would not work again in the original position where it has worked well for many years.
Obviously DAB requires a good strong signal as I am living very close to the transmitter at Mounteagle in the Black Isle and the set is upstairs in the house to achieve the highest signal into the set's whip aerial.
Another annoying query I can give you is this :- Every time I do a full AutoTune operation on the DAB receiver , it ALWAYS comes ON tuning BBC Asian 1st. so that station comes up as a 'Favorite' on the Radio's screen. No matter how many other stations I select and listen to for at least 20secs. say, the BBC Asian one STILL is listed as a FAV.
Is this a peculiarity of the Sharp design or a function of the transmission system?
Maybe this BBC Asian is on the first freq. the DAB Radio scans, but I would have thought it would come ON every time with the last station which was selected before it was switched OFF.
What do you think ???

I am trying to re tune to my local radio station radio Merseyside on dab but it says station not available or goes to another station ?


Have you checked the frequency of that Station?
Also check your aerial.

I have also found this:
Listeners to DAB digital radio in the Merseyside area will need to retune on Wednesday 20th April following a frequency change that will affect local radio stations.

The local DAB multiplex carrying BBC Merseyside, Radio City 1-3 and Capital Liverpool among others will be moving to a new frequency in order to allow better reception over a wider area. The current frequency will be turned off late on Tuesday 19th April. The new frequency will go live from 6am on Wednesday 20th April, after which listeners will need to rescan their DAB radios in order to continue listening.

Fm radio works fine but the dab will not find any stations, I have tried different aerials and still no good


What's the make & model of the radio?
Most DAB/FM radios work from the same antenna, so if you receive FM stations, you should receive DAB stations in your area.
It should be noted that DAB transmitters work on lower power than conventional FM transmitters, and so you may be in a weak reception area (for DAB). It should also be noted that DAB uses different frequencies than regular FM stations and household appliances such as laptops,WiFi, microwave ovens, etc can affect DAb reception.

HOW DO I GET MY CDAB5IR STEREO DABRADIO TO WORK


The first thing is to consider what DAB signal quality you have there. It might not be strong enough. Digital radio is not like AM/FM, it simply goes off altogether if the signal is weak.

I would take it to the shop and ask for assistance, or get next to a DAB radio which does work well. Then recheck things like settings, tuning, and a good battery in it (I think that model is a smallish radio?)

How to preset favourite dab stations on matsui dr100 i have no instructions


This budget radio from Matsui allows you to enjoy the wide range of benefits of DAB digital radio for a very affordable price. The R100 is powered from the mains and features stereo speakers to allow you to really enjoy the clarity of digital radio.
Digital radio offers more station choice in more places, meaning that digital radio has something for everyone. DAB even has easy tuning, therefore you no longer have to scroll though numbers to find the exact frequency and you no longer have to remember the frequency numbers as with DAB you scroll through station names.


hope this may help;

How to reboot hitachi dab radio


Sounds like what happened to my Sharp DAB receiver recently . - Swtch OFF completely from all power sources and proceed with the recommended RESET function.
Move set and/or aerial to be sure of a good strong signal before attempting a complete re-start and full AutoTune as per the instruction manual.
This operation certainly cured my problem although I never have found out what caused the failure in the first place!!!
