We ARE
here! There is a moan on one of the news groups that we don't
answer our emails. Well anyone can be busy or have a bad day but
we DO try to answer every email that we receive - within a few days at
most. So if you email and don't get a reply please don't just
moan. Perhaps we didn't get it, check that you have actually sent
the email and it's not stuck in your out box - then try to send it again.
Also check that our reply isn't trapped with your ISP as
spam. Thanks! |

FREE
BARRACUDA BOARD REPAIR
OFFER SUSPENDED
We made a spectacular free repair offer earlier in the
year to attempt the
repair of some bricked IR100 Reciva Barracuda Module faults using a
novel process. This was to give us experience using
the new method, and maybe just to help a few people out too! This offer sort of backfired as although
most repairs were successful we were sent several modules in
envelopes completely
unwrapped and without
proper postage paid so we were expected to fix boards cracked in
transit,
unbend pins and even pay
excess and return postage to fix a board for
a "free" repair. We have therefore suspended the offer. It
MAY return later!

UPDATE CONCERNING
THIS ENTIRE PAGE AND IP RADIOS GENERALLY
18 July 2010
The Logik IR100 internet radio has now been
available for more than 5 years. They were made very cheaply (too
cheaply) in China for the Dixons Stores Group and have never been
too reliable - for some of the reasons look lower down this page. In the
last few months our email inbox has been growing larger each day -
mostly containing emails about Logik radios with faults of a terminal nature. In fact it is true to say that
radios that have been plugged in continuously are now more likely to be
faulty than not! If YOU have had your radio plugged in for years and it
still works then you can count yourself lucky indeed! You probably live in
an urban area where the electricity supply is reliable and comes
in underground, as constant mains failures are definitely a major cause of
problems in these radios. The time is right for a replacement model to
be designed. So what to do?
As far as we are aware there seems nothing on the
market comparable with the Logik IR100. Roberts make a great Internet radio
- my son has had one for 2 years, it cost £150 and has now gone up to £170,
which proves how good it is! Others manufacturers make IP radios, one is
available on eBay for about £70 or so. The model is much smaller and the
audio quality is not nearly as good as the Logik.
The reason for these paragraphs therefore is to ask if
YOU know of an IP Internet radio that retails for £50 or so PLEASE let us
know so that we can tell others.
It seems manufacturers are missing out here too. There
is certainly a demand for a reasonably priced IP or Internet radio, yet
nobody seems to be marketing them properly. I expect the main reason - and
the main reason why Dixons dropped the Logik - was the problem explaining
the concept and installation of a radio that uses a wireless router rather
than an aerial. However I think that with I Phones and similar the public
are now better informed at the possibilities of using their router with
other things than computers. IP addresses and subnets are now far better
understood. How about it manufacturers? I have been fixing these
radios since they first came out, used to work as an engineer for the BBC,
and would be delighted to advise an entrepreneur or manufacturer about the
necessary, and unnecessary, facilities needed!
There is no reason at all why a reasonable quality IP
radio could not be manufactured in China for $15 FOB. That would mean that
it would sell for £55 - £60 in the UK and the equivalent cost in the rest of
the world. It CAN be
done! Please get in touch if you'd like my advice on design or can suggest on
suitable
models. My dedicated address is logik at horsted keynes dot com (all lower
case no gaps).
The Logik IR100 is an Internet Radio
also known as a Wi-Fi or Web Radio; that is it connects to your existing home wireless
broadband network and
enables you to connect to any of more than 8,000 radio stations almost
anywhere in the world without needing a computer! It also lets you
listen to audio files that are stored on any computer on your home
network and works particularly well with the new Microsoft Home Server
that is discussed elsewhere on the Horsted
Keynes web site. Alternatively you can listen to more than 24,000 audio streams
from all over the world such as the BBC podcasts! Unfortunately many of the people employed to
sell these radios don't explain that for them to work you
must have a
working wireless network in your home but you do not need
a computer at all! If your internet radio doesn't work with your wireless network then we can modify your receiver to work
instead with a wired
network - more on this later.
An internet radio station can use a number of different codecs including Real Audio (RA), Windows Media (WMA) and MP3 (that's
mp3 ;-) and this radio will work with all these and more. Any operating parameter can be altered by firmware updates
which are automatically downloaded not from the manufacturer's web site,
as would be normal, but from reciva.com who make the processor
board that is at the heart of this and many other Web Radios. Their web site
also updates the IR100's internal list of radio stations and acts as a
hub to store your personal preferences. At present this is all provided
free of charge but we think it only a matter of time before they are
forced to start charging for their services. A recent posting from their
owner says that their service will stay free however, we do hope so!
So to make it 100% clear, as received this radio
requires
a working wireless home network like a BT Home Server or a Netgear or
Belkin Router - any make will do! Your network can be encoded or in the clear
and you do not need a computer running
anywhere in your home to listen to internet radio! Besides this you can
also listen to all the stored "on demand" programmes on the BBC web site as well as podcasts. This sort of radio can be a very useful addition to your home
entertainment setup and is capable of giving really good quality audio
which can be fed into your home Hi-Fi through a socket on the back.
They are frequently used as a bedside radio and for this they have
a built in alarm clock. Alternatively perhaps you prefer to listen to the
"Today Programme"
or a repeat of "The Navy Lark" in the kitchen. There is a very high quality 8 Watt mono loudspeaker
inside as
well as the afore mentioned stereo headphone or HiFi socket on the rear.
Now these are some of the plus points of this radio, but like any
technology they also have their problems!
Firstly, be very careful where you buy your Logik IR100.
If you buy new at full price (if you can find on in a shop these days) then there is no
problem, but unfortunately whilst this design is still being made (in a variety
of colours) it is no longer being sold by PC World or Curry's so the
second hand route seems to be the way that you must go. The problems can come when you buy one of these radios
from an eBay seller who does not disclose that they are selling
units that have been returned as faulty or are customer returns! They
often "forget" to mention this in their product descriptions then sell the
radios as "new"! Now some of these
radios will have little wrong with them as they were just returned by
people who bought them without realising they needed a home wireless network to make
them work. Some other radios bought from eBay will have serious faults (frequently
intermittent - important see below) which do not show up until several days after purchase, and items bought on
eBay do not come with any guarantee at all! Caveat emptor, and
then caveat again!
One tip is to see if the seller includes an
instruction book and a box in the sale. Whilst not infallible if these
accessories are included
then at least you have a chance of getting a genuine bargain.
The most well known and common fault with this
model of Logik
radio is a loud mains hum that emanates from the
loudspeaker even when the radio is switched off. This can be particularly
annoying when the radio is placed on a bedside table as the hum cannot
be turned off without removing the power and stopping the alarm! There is a fairly simple modification that many
can do at home to make this hum much quieter, please get in touch with
us if interested. Sometimes the selector switch is intermittent or slow
to register while other problems are a general lack of wireless
sensitivity.
Then there is the fault that causes some
headphones to fail if they are left plugged in when the radio is
switched on, this has happened to us - twice now! This is because of a
design flaw that gives a large power surge when the radio is switched on
from cold. As well as the left/right control knob being faulty quite
often the selector switch itself which is built into the left/right knob
gets "iffy" and has to be pressed very hard before it works. This means
that after a few hundred presses (and you have to press this button at
least four or five times every time you select any station) the switch
mounting plastic breaks off completely and the radio is rendered
completely useless. Fixing this problem involves replacing the rotary
encoder.
Another problem has been around from new, these radios
sometimes "brick", a
term which means that they just sit there looking at you with no light
showing at all. The problem is sometime preceded by the sound "babbles" and
then the radio simply
fails to turn
back on. This is becoming a more frequent problem as these radios get
older. There are other causes and such faults can sometimes be fixable
but dead radios are seen much more often as the design gets older.

WILL MY LOGIK IR100
WORK WITH THE THREE MiFi DONGLEill?
We were recently asked this question and it's
a good one so we thought we would try to find out for you.
The MiFi is a small dongle sized device that
includes a Three mobile internet connector and a four way wireless
router. It is designed to enable you to connect your wireless
computer to the Three internet when either away from home or if you
simply prefer to use the Three wireless network.
To cut a long story short Three block several
ports on their connection, some of which are used by the Reciva
Barracuda control module.
So "no" the Logik IR 100 Radio will not work
when using a MiFi for internet connection. Sorry! |
|
LOGIK IR100 LINES
MISSING OR DIMMED ON THE DISPLAY
As this involves a lot of disassembly WE WILL NOT BE RESPONSIBLE if the
following suggestion
doesn't work for you, so please only attempt it when the radio is otherwise useless. Having said that
this is not the most difficult repair either. It just requires care.
As these somewhat cheaply made radios age they
are beginning to develop some of the faults common to ordinary
radios that come from China. One of these is a display that is
either corrupted or has lines dim or missing. Below is a picture of a
humdinger of a fault that appeared on one of these radios whilst in our
workshop. As you will see not only is the very top line dim but the
bottom two lines are actually showing as double height Cyrillic!
This just shows what a microprocessor controlled display can do when
it goes iffy!

An unusually bad display in our workshop. Apart from the double
height
third line, if you look at the very top of the S in the display you
will see that it is slightly dim.
Now whilst this problem may look catastrophic it
can in many cases be fixed without even switching on a soldering
iron. You DO however need to be confident enough to open the case
and then completely disassemble your radio. If it's just one or two lines
missing or even just dim then if you are not confident we suggest
that you leave well
enough alone!
If you do decide to go ahead then we won't waste
your time with all the safety rules, take them as read. Just make
sure your radio is completely unplugged from the mains (doh!) and
probably best left for a few hours so that the capacitors can
discharge.
To attempt a fix of this problem you need to get
at the display module which is right at the front. We have some
notes here which although written for another problem on these
radios may well be of help to less experienced people. Download it
from http://www.horstedkeynes.com/ir100manual.doc . This
manual is a work in progress and some of the pictures are yet to be
added.
Once the display board is removed from your radio you
will see 6 tabs that we have circled in red. You need to loosen
these tabs, wiggle the display a bit to wipe the contacts and then retention them. That's the fix! You see the
electricity gets to the display through some "conductive sponges".
These are very clever devices that were first used in pocket
calculators and are sandwiched between the display itself and the
back of the display control board shown above. The advantage of
using a conductive sponge is the manufacturer saves many tiny
electrical connections, the disadvantage is that is all that there is to
conduct the electricity. Over time the
sponges begin to deteriorate and flatten so you get poor
connections, often improving as the radio heats up. To effect a
semi-cure
you have to loosen and then put
the display back where it was but now under a little more tension.
This should buy you a few more years' use.

Shown above are the six tabs on the back of the
display module that require retensioning. The four black blobs are,
believe it or not, microprocessors that decode the data from the
Barracuda Module into letters and numbers! There are probably 7 or 8
million transistors under each one! There is a lot to go wrong in
these radios and this is why you can get problems like double height
Cyrillic symbols!
After reassembly it is quite common to get no
display showing at all or perhaps a line that is lit but not showing
any letters. This is caused by the microprocessor crashing. To fix this you need to reboot the
entire radio from the Barracuda module. The
easiest way to do this is plug in the radio to the mains but after
having removed the network card from the USB socket. With luck you will
then see "No network Card Present" bright and clear on the
display. Do NOT plug the network card
back in until you have switched the radio off. Yes we know that some
people advise plugging it in as the radio starts up. In our
experience this is one great way to blow the Barracuda module
entirely as the USB is not buffered and gets its data straight off
the Barracuda board control lines. Another cost saving of a couple of cents
that causes bricked radios!
Please let us know how you get on for you and if it works
a few pounds Pay Palled to us to help cover our hosting costs would
be greatly appreciated!
Remember as stated above only try this suggestion
if you
know what you are doing or have nothing to lose such as with an otherwise
unusable radio. The fault above is to try to fix a corrupted
display, a totally blank display on a radio that does not even light
up - that's a "bricked" radio - will NOT be cured by the above
procedure. |

DEAD "BRICKED"
LOGIK IR100 RADIOS - A POSSIBLE REASON
We believe that we may have found one of the main reasons why
these radios fail so often and why when they fail they frequently
"brick", i.e. go completely dead with no display and no sound. Once
dead these radios seem to stay dead!
The Reciva Barracuda board inside these sets is the absolute heart of the
Logik IR radio, it controls every function from decoding the sound,
working the display, talking to the internet to decoding the
volume control. When this board fails the radio goes completely dead
with no display at all and of course no sounds to listen to. The
little red light inside also SOMETIMES goes out. We have capitalised
sometimes as they dongle light used to always go out when the micro
failed in these radios, but we have recently discovered that some
different makes of module stay alight.
This Reciva board requires two voltages to work, one at 3.3 Volts
and the other at 5 Volts. This power comes from the radio power
supply board via a ribbon cable. This power supply board is made to the lowest
standard that we have seen for ages, the soldering is poor, the
components are cheap and put in at any odd angle, and the supply voltages go from this power supply
to the Reciva board via ribbon cables that are held in place at one
end with hot melt glue! Like the rest of the Logik made parts it's a complete and utter mess.
Now the 5 Volt supply is controlled by a large 3 pin 1 Amp regulator on
the power supply board; the regulator is screwed to a large heat sink to
help keep
it cool. Heat sinks are made from heavy lumps of aluminium so they should be
fixed to the circuit board first and the
regulator then attached and soldered in. This makes a solid
module which is secure and safe. In these sets the heatsink is often not attached to the board at all (or the fixing is
lose) so the 3 thin regulator wires support not only the weight of
the regulator itself but that of the heatsink too. It is
therefore not surprising that these wires come lose or even break
causing the 5 Volt supply to become intermittent and eventually fail. When this happens it puts
the Reciva Barracuda control board into a funny mode (often starting with a
"gurgling" or "bubbling" type of sound) and the radio switches itself off
never to return! Thereafter the radio completely fails and stays completely dead and useless. In modern parlance it is
"bricked"! Fixing a bricked Logik IR100 is not easy as it
requires the processor be reprogrammed.
There is sometimes a warning that this failure is about to happen
when the radio makes loud crackling type sounds, for some odd reason
often when listening to a pre recorded "listen again" file. If this
crackling starts on your radio get it fixed immediately by a
competent engineer or start to look for a new internet radio! At
this stage the repair takes just a blob of solder and some heatsink
compound. This
fault is one reason why you should never buy one of these
radio from eBay when it is described as having an intermittent
fault! The seller may well not know that their radio is about to
expire so how can they warn you - that's even if they wanted to!
Once the radio stops lighting up, even if you get the original
connection resoldered it's too late, the control board stays dead as it is stuck
in this funny mode which prevents it booting up. We have found no way
to resurrect the Reciva boards after this has happened - although we
may have news on this soon.
We believe this one lose 5 Volt connection caused by poor
construction and poor design is the main reason why the Logic IR100
radio is becoming so unreliable.
So whose fault is all this?
The Chinese radio maker must take the main responsibility as
their construction is dreadful with many poorly fitted parts that
require manual resoldering after automated assembly,
and the design using glue to hold wires to the board must be
deplored. But the designers of the Reciva processor board must also
take some responsibility as their board requires three power voltages
to work. One is already converted from another on the board but why
chose to have the other supply come such a long way? Had they placed
one more power regulator on the Reciva
control board itself it might have cost them 50p more to manufacture, but
these radios controls could be have been run from a single voltage which if it
failed would not be terminal. It's only when one voltage fails while
another stays working that the problems start! There would in our humble
opinion, be far fewer dead logic radios in land fill sites or boot
sales had this been thought of!
If your radio has "bricked" we would love to hear if you had the
warning symptoms described above. And if you have managed to fix a "bricked"
radio naturally we'd love to know how you managed it! We believe
that a micro processor expert might be able to make some spare cash reflashing these "bricked" Reciva modules, by copying from a working
set (although the serial numbers would need sorting out). How about it? Please email
logik@horstedkeynes.com
with your thoughts or suggestions as to how we can get these great
little radios working again. |
We are retired electronics engineers and are able
to fix some of the problems with these radios however some of the parts
are "specials" which are hard if not impossible to find!
Because some older people find these radios
especially easy to use we like to help them by fixing their faulty sets
so we need to have a stock of spare parts. If you don't want to bother
to pay for
your radio to be fixed then we may well be prepared to buy your Logik IP radio
so that we can salvage its spare parts which are generally unavailable from normal spares
outlets. We will consider paying you cash money for your Logik IR100 WiFi
Internet Radio, working or not. In the section below we list the
prices that we are usually able to offer. The fee paid includes the postage for you to send in the radio,
or of course you may bring it to us by hand.
Given that you may have bought your faulty radio for £20 on eBay we feel
that our offer for what is in reality a broken 5 year old item is a very generous
offer indeed! However we must point out that these radios are really
showing their age and are much less reliable than many buyers (and we) would
wish. This means that we have in recent months been offered up to several
radios each DAY and as our finances are limited we are not always able
to buy radios, even when we would love to!
Your radio may not have sound but it must light up (even
if it just shows squares in the display) for us to be able to pay
you the most money. We will still make you an offer if your radio is completely dead and does not even
attempt to light up when switched on but in this case the main Barracuda module has probably gone and we would
only be able to offer you a smaller sum for it - nevertheless do
please contact us as we might still be able to recover some of the
redundant parts.
Because of the large number of these radios going wrong
and also because of
storage problems we are unfortunately not able to accept every radio
offered particularly if you expect a lot of money for it. If we are not able to do a deal
the first time then please
do consider asking us again a few weeks later when we may well have some
storage room to spare. It is better than dumping a broken radio in the
landfill, isn't it?
If you would like to sell us your Logik IR100 radio
(working or not) please email
logik@horstedkeynes.com with whatever details you have about it and with
any faults or symptoms clearly
stated so that we can see if we are able to make you an
offer. If you accept our offer we'll be in touch to sort out the details. Payment to you would be
from your choice of Cash, Cheque, or Postal Order. Alternatively if you live reasonably near to us in
Sussex then we will happily give you cash on the doorstep - indeed we'd be
delighted to meet you!
Needless to say
you must be the owner of any radio
that you intend to sell us. Fair
enough?
|
To help cut down on the number of emails that we
receive - all asking the same questions about the present value - we will now try to give you an idea of how much
we may be able to offer for your Logik IR100 Internet Radio
in the different conditions that they come. We fix these radios as a hobby and also for older
people who find them easy to use. To save money we can extract some parts from
broken radios which makes repairs cheaper. The prices we are able to offer are very fluid and
are based on what we presently have and whether we urgently need a particular part at a
particular time. We may be able to offer a bit more or less for sets
in particularly good or bad condition. If you look on eBay for the
current price that sellers have achieved do remember that using the
eBay system will entail your paying their two sets of (rather high) fees as well as the
inconvenience of having to place the listing in the first place, take photos, packing up,
dealing with lots of stupid questions etc., etc. Our
price is an immediate CASH money offer!
Just to cover ourselves
we reserve the right to reject any radio after receipt without
saying why! In such circumstances we would ensure your radio was
returned at no further cost to you. We look at these radios as a
hobby and to help older people who find them easy to use, we are not
a multinational organisation! ;-)

PLEASE NOTE THE FOLLOWING PRICES
WERE SET IN APRIL 2010 |
|
Fully working in all respects, boxed and
looking as near new as makes no difference.
This top price would assume that the display light is still
bright - they are wearing out on sets that have been left
switched on with the back light on full brightness. Please be aware that the last stock sold
at Curry's Digital in February 2009 went for £29.99. That puts
our offer in perspective! |
|
£20 - £30 |
| |
|
|
|
If your set lights up in some way but has no
sound, it may just show squares on the display, or perhaps stuck
showing a static word or two, fairly clean possibly with box
etc. |
|
£10 - £15 |
| |
|
|
|
Not working, but reasonable case (no
dents!) possibly with instructions or box. Does NOT light up,
looks and feels totally dead. All parts must still be there! |
|
£7 - £10 |
| |
|
|
|
Not working, dirty scratched, no box or instructions.
Does NOT light up, looks and feels totally dead. Most parts still
there. |
|
£4 - £10 |
| |
|
|
|
Sets that have been "looked at" by your friend who mends
radios, fixes washing machines and plasters walls in their spare time
- true!
We are more likely to buy several together in this state!
(Price is really just to save them from the landfill.) |
|
£1 - £5 |
|
We will consider the CASH purchase of OTHER makes of Internet or
IP Radio, whether working or not.
PLEASE contact us before
dumping any internet radio in a skip or landfill.
We may well be able to buy your IP radio before you put it on
eBay.

Now the above very special offer is out of the way we have a second
one if you just want your radio to work again.
If your radio has a problem that is not due to
one of the mechanical
faults mentioned above which requires a hard to get spare part we will be pleased to offer
you our
personal help resolving the issue at home and without your having to
send it in.
For example if your new IP radio simply refuses to
connect to your router we are often able to walk you through the
problems, and will look up to see if there is an insurmountable conflict
somewhere. If we manage to get everything working to
your
satisfaction then all we ask is that you pay us a minimum donation of £10 which goes towards the cost
of running this web site. You only pay us after
we have helped
you (we tend to trust people). If you are not happy, or we can't fix your
problem then our advice will have cost
you nothing!
The minimum £10 fee is for problems that are fixed by
you at home following
our specific directions. You may have to take the back off your radio
(if you chose to) and in such circumstances we
expect you to be careful to unplug from the mains (doh) and put it all
back together carefully afterwards. We are not looking over your
shoulder but it just takes a bit of common sense. Sometimes soldering may be
necessary but this is not always the case and obviously you don't have
to go further than you want attempting any repair.
If we have to have the radio in our workshop to sort it
out then our
fee will quite naturally be somewhat higher, in fact probably more than
your radio is worth! Remember these radios were made down to a price and
many are now suffering from major reliability issues. Some users are
lucky whilst others seem to have a "lemon" that has been unreliable from
new. In particular the control microprocessors are now failing with some
regularity. These give various faults but mostly the radio just won't
switch on at all, often following a power failure, but sometimes after
hearing a funny baubling sound it just refuses to restart! Radios with these
faults in particular are ending up on auction sites such as eBay and are
often sold as having an "intermittent fault sometimes will not switch
on"! If your micro has gone then unfortunately take it from us, your
radio may be beyond economic repair.
Roberts make a wonderful radio that covers ALL
wavebands from VHF via Digital Radio to Internet Radio, it sells for
nearly £200; your Logik probably cost you £40 new - remember you gets
what you pays for!
If you get in touch, we may take a few days to
reply. If you do not hear from us within say a week at most please feel free to email again as
sometimes messages just do not arrive, or our answer gets trapped as
spam the first time.
April 2010
clarification
These sets are becoming increasingly unreliable. When
you consider that many of them are 5 or more years old this is hardly
surprising. As mentioned above they were badly made when new, on top of
their being made of the cheapest, lowest quality parts imaginable, this
makes them more than likely to fail sooner rather than later.
In the past we have been happy to take a look at any
faulty Logik radio that arrived at our door. Whilst we can still do this we
must point out that the commonest faults can be caused by any of a number of
parts and our stock of parts is severely limited - we are not a business
after all!
For this reason we feel that it is time to state that
we are no longer able to offer a normal "repair all" service (except in
exceptional circumstances). We are still keen to buy your faulty sets as
there are older people who would like to have a set to listen to and we can
use the working parts for our stock. Apart from
the odd exceptional case however we regret that repairs must now come at the end of our
list of facilities.
