Outstanding coverage, simple to use, nice build quality! Just wish there was an OSX driver. Highly Recommended!

Fantastic - I\'ve been struggling to listen to Radio Caroline for years. This puts it on my tranny where it belongs, but crystal clear and in glorious stereo.

Just bought & installed the Keene Electronics FM Transmitter & have offered 5 stars. Easy to use & install. I should point out the HiFi equipment I'm using dates from 1961! The PC is downstairs, & my Leak Troughline II is upstairs using an external aerial & Stereo Decoder. When the Keene Electronics Transmitter is positioned correctly, it works lovely, which means when FM goes, I can still enjoy real HiFi & condense my CD collection :O) Only real criticism? The lower (Bass) frequencies are a tad recessed & high (Treble) frequencies a tad prominent, but this is more likely down to computers & compression ratios. It's alot like listening to local radio ... WITHOUT the commercials & budget presenters ... To save toggling between soundcard & FM USB in control panel, I use media player on the soundcard & iTunes for the FM transmitter ...

As mentioned it works well on W7 x64. Only downside is that you have to swap between your normal soundcard and USBFM to use normal speakers or FM. To get 5 stars Keene need to include a simple desktop app that does this automatically. A simple on/off button would suffice.

Excellent device! I use it on a netbook PC which holds all my music, and carry it around to wherever there is an FM radio, including the car. Also great for podcasts, audio books and internet radio. Much easier to use than my dedicated internet radio.

This was on my Christmas list and I can tell you "it does everything it says on the tin". I can now stream my WMA collection all around the house and it works a treat. Combine it with the Vectir WMA remote app for mobile phones (see www.vectir.com) and you've got something equivalent to Sonos/Logitech music system for £20 plus all your old FM radios - and if you're like us, there's an FM radio in every room already. Outstanding value.

Just got mine today, installed it and I had to put the Radio receiver on top of the USB FM in order to get some signal from it. It’s a waste of money....
8. Mike T 18 Oct 2011
I bought one of these from the Radio Caroline web shop a couple of months ago and it's without doubt the best fifteen quid I've ever spent. It was a little fiddly to set up on Vista (but nothing is easy with Vista). We have a stone built house with thick walls, but there's nowhere the signal doesn't reach and even gives me good reception out in the garden. Well worth the money. All you need extra is a decent fm radio and you've got yourself great quality internet radio or whatever else you choose to play through your pc. I recommend it wholeheartedly.

I wrote the very first review of this product many moons ago- and having recently upgraded to a Windows 7 operating system 64 bit- I can only reassure you all that it DOES work- certainly with the downloaded software.
10. Dave R 30 Apr 2011
I have bought many mp3 FM transmitters in the past and often felt disappointed with the overall signal strength and poor audio quality BUT this little beauty works very well.It's easy to install the software and "set up" in no time at all. With good positioning and a bit of adjustment the signal is rock solid and covers a greater distance than any that I have used before. Both music and speech sound pleasing either through a good system or a portable radio. The little background whine heard when used with the supplied USB lead is quickly resolved by using another longer lead. Recommended. With a longer USB lead I found the backgound noise very low and signal strength stronger than before! This device makes life really simple when it comes to listening to your PC or Laptop around the house and garden and maybe beyond on any FM receiver! This is a great way to rekindle all of your old analogue FM receivers/tuners and save yourself all of that expenditure and technical headaches by avoiding the digital streaming route. Keep it simple. PS This device is so good that I ordered a second one! .... and "Keene" post these out very quickly too in decent packaging.

What a revelation! I'd previously been using a Linux transmitter Fm-Transmitter/dp I bought about 8 years ago, and, despite its infuriating nature, I'd never really found anything else that fit the bill for use at home, wanting to transmit music from my laptop to the big stereo speakers in the lounge. When I last trawled through the internet, all I could see was iPod ones that run off a car cigarette lighter... Then I found this. Why-oh-why did I persevere for so long with the old stuff? While the software's user interface looks a little dated, it's perfectly easy to understand, and took about 30 seconds to install and start transmitting! And all through something as small as my USB mouse receiver.
13. Jeff 03 Oct 2010
Produces a very good, clean signal, easily picked up throughout the house. For the sake of good relations with the neighbours, just remember to listen, listen, listen to the frequency you want to use before starting to transmit. For those who happily use old gear, both the software and the device happily work on Windows 98SE.
14. Andrew S 17 Sep 2010
Wow great product, well worth the money, excellent quality and stunning coverage. I have the device attached to my computer on the ground floor and on the 3rd floor of the house a small bathroom radio picks it up with no problems.
15. Glenn C 02 Jun 2010
Have just installed the transmitter and I am very impressed with the quality (even through my Bose Radio) Just remember if you are using Foobar 2000 to change the Output setting in Foobar.
16. William H 21 May 2010
Its just BRILLIANT! Its also a totally UNIQUE product-in that it utilises your pc sound card as a sound stage. This means the audio quality of the broadcast signal is not compromised by DAC processing. As a result-the audio input to your receiver is identical to the output to this transmitter. I have mine attached to my PC upstairs-and I can play the audio downstairs on my stereo- with absolutely no loss of quality. The signal reaches every room in the house-and only fades as you exit your house-so it does not interfere with your neighbours reception at all. My recommendation- BUY IT! For £14.99 you won`t find anything better.

1 Andrew on 18 Mar 2012 asked :
"My Audio Transmitter works brilliantly on a Windows 7 64 bit machine, however, if there is a pause in playback, for example, in playing a DVD if the DVD is paused for a few minutes, then the transmitter turns off. Is there a way to stop the transmitter switching off while it is connected to the PC?"
Keene replied: We are not aware of anyway round this...
2 Gregor B on 12 Feb 2012 asked :
" Does the transmitter get in nearly future RDS?"
Keene replied: No it i does not transmit RDS
3 Josh on 04 Feb 2012 asked :
"Can I make it start in play mode when opening the program?"
Keene replied: No sadly not.
4 Steve on 21 Oct 2011 asked :
" I AM USIMG FREQUENCY 103.0 BUT WHEN I TURN OFF COMPUTER IS GOES BACK TO DEFAULT FREQUENCY AND YOU HAVE TO SET AGAIN, IS THERE ANY WAY TO SAVE MY FREQUENCY? RGDS STEVE"
Keene replied: In the program folder created during the installation there should be a file called config.ini This is the file that stores your chosen settings. If you examine the date & time stamp on the file it should show as the last time the program was used? It might be worth re-installing the program entirely in case this file is missing or corrupted.
5 Nick p on 21 Oct 2011 asked :
" would i be able to use this through my main Hi-Fi Sony tuner thank you "
Keene replied: Yes
6 Nic c on 01 Sep 2011 asked :
" will it work on a mac sys x"
Keene replied: No
7 Barry on 02 Aug 2011 asked :
"I have bought one of these and I must say how impressed I am with its quality and range. I am very pleased with it, especially as at this moment I am running it on Windows7 64 bit! All I did was to right click installation file and go to 'Troubleshoot Compatibility' & installed it that way. I downloaded the file from the web site instead of using the CD."
8 Nonny on 19 Jul 2011 asked :
"Can the transmitter be used in the US? Is it marketed there?"
Keene replied: It is legal for use over here in the UK but we can not comment on the US. Sadly it is not marketed in the US at present.
9 Phil on 10 Jun 2011 asked :
" Is the device CE conform and got the CE-mark (http://en.wikipedia.org/wiki/CE_mark)?"
Keene replied: Yes it does.
10 Nozzer on 08 May 2011 asked :
"Can I use this with an IPad?"
Keene replied: No iPad does not have a USB port or FM radio implemented.
11 Barry on 28 Mar 2011 asked :
"Are you going to release drivers for Win7 64 bit?"
Keene replied: This is now compatible
12 Bob B on 28 Mar 2011 asked :
"I've installed the USBFMT on my laptop using XP pro sp3. The device appears in "Device Manager" and is apparently operating correctly. However when I open the software the frequency is not displayed, there is just a button in the centre which looks like a "Pause" button. Clicking this does nothing. Is there a fault with the unit or am I diong something wrong? Many thanks for your help."
Keene replied: Click the Play arrow on the left hand side. Frequency will then be shown use the left and right arrow to adjust.
13 Alan M on 16 Feb 2011 asked :
"I've just purchased and installed the USB FM transmitter and it seems to work well. How do I toggle the sound to play back through my laptop speakers when I don't want to transmit to a nearby radio. I can't seem to undo the usb fm transmitter audio. Thanks "
Keene replied: Go to control panel "sounds and audio devices" or something similar and change the audio out from USB audio to your normal default. You would then need to change back to USB audio when you wish to re use the USBFMT.
14 Dan on 29 Jan 2011 asked :
"Does this work with Windows 7 (64 bit) yet?"
Keene replied: Yes
15 LM on 25 Jan 2011 asked :
"Please could you specify the Audio Frequency Range for this product. Would it be able to transmit RDS? In order to achieve this the device must be capable of playing audio with a sampling rate of 192 kHz. Is the stereo encoder hardware based with a software switch, or is the stereo encoded within the software."
Keene replied: Unfortunately no it doesn't support RDS. The sampling rate and frequency range will be determined by whatever is originating the audio, the PC is effectively passing the decoded output to the USBFMT which is itself a purely analogue FM transmitter. I hope that helps,
16 Paul K on 17 Jan 2011 asked :
"I have written a quick and dirty program that enables me to control the radio side under linux. You can find it here https://github.com/kenchy/keene-usb-audio It works but I am still refining it. Hopefully other users might find it useful."
17 Dan on 09 Jan 2011 asked :
"i I am very interested in your product as I use a program called "Sam broadcaster" which I can transmit music and audio via mic and recently found out you could transmit through FM frequency. This would be fantastic to use if I could transmit to radios through the house. Firstly would this work with "Sam broadcaster", and I have noticed you haven’t given a figure to the range I know it depends on thickness of walls and how many walls but was wondering if you could give me a rough estimate please ?? Many thanks Dan."
Keene replied: We couldn't really comment on "Sam broadcaster" as we have never used or have any access to it. With regard to range the radiated power is limited to 50nW by the DTI. Its impossible to say with any certainty that this equates to a specific range in metres as there are other factors that will affect it. In practice so far it has worked in every domestic house room to room and upstairs to downstairs. The applied USB extension cable also acts as a signal booster to extend range. All I can suggest is to try one and send back for full refund if it did not work or you were unhappy in any way.
18 Andrew on 06 Jan 2011 asked :
" Just what I've been looking for..to listen to iPlayer programmes in the bath! But I'm confused by some comments from reviews eg 'I hesitated before buying the Keene unit, but no need. Now I can stream to all the FM radios in the house and though the sound can't match the digital audio sender I mentioned, take time to set it up properly and consider a better extension cable (I'm using the one that came with my Vodafone broadband dongle) and you could have a *lot* of enjoyment from this. Where does the extension cable come in? I thought there is just the dongle...and the radio tuned to the fm frequency?? "
Keene replied: Yes it is included.
19 John M on 05 Jan 2011 asked :
" As a pretty non technical person, could you confirm that this device will send an internet radio station (ie Radio Caroline) to my Bose unit downstairs from my computer upstairs, once I open the listen option on their website Many thanks John"
Keene replied: Yes this will be perfect.
20 Steve C on 03 Jan 2011 asked :
"is it easy to switch between using your PC sound card and the transmitter? I am running Windows Vista!"
Keene replied: Yes you just go to Control panel>hardware & sound>sound in the playback tab click on 2 B-LINK USB Audio and set as “default device” Then set back to sound card when needed.
21 Fom on 16 Nov 2010 asked :
"Not a question but to build on what Rob H said below. I'm using MPD (Music Player Daemon) on ubuntu 10.04 and I can now listen to my music collection and any radio stream I want on any FM radio in the house. Just follow his tip for setting up under wine / winetricks. After you have it setup to a certain frequency that works, no need to even run the USBaudio.exe file anymore. Can help out anyone with the MPD setup if required.. Class product, well worth it!!!! F"
22 Conrad on 09 Nov 2010 asked :
"Is this legal and does it work in the USA?"
Keene replied: It is legal for use in the UK but we couldn't comment on USA.
23 Gaz on 25 Oct 2010 asked :
"I have a question about "USB FM TRANSMITTER" Does this work with Linux?"
Keene replied: I got this working under Linux, and it works fine, without too much effort. This was on a 4-year old Sony laptop. I used Ubuntu 10.04 netbook edition. I had to install mfc42.dll (using winetricks as detailed at http://machine-cycle.blogspot.com/2009/10/wine-and-missing-mfc42dll.html ). The installer ran fine. Then under Ubuntu\'s sound settings, on the Output tab, select the new device. It then worked without any other complications, and routed all sound from Ubuntu to the device.
24 Rob H on 22 Oct 2010 asked :

25 Martin C on 04 Oct 2010 asked :
"Does it really only use 50nW?? This is an incredibly small amount of power considering you're transmitting RF..."
Keene replied: es this is correct a review that may be of interest:- http://www.reghardware.com/2010/09/27/review_gadget_keene_usb_fm_transmitter/
26 Clive G on 27 Sep 2010 asked :
"Does the included USB extension lead function as an aerial? A Register review ( http://www.reghardware.com/2010/09/27/review_gadget_keene_usb_fm_transmitter/ ) claims it does, but I don't see how this can be at all possible. I tried to post on their forum to ask this, but the moderator deleted my post. Can you clarify one way or another?"
Keene replied: The USB extender cable is included and acts as an antennae to boost range.
27 Mike S on 24 Jun 2010 asked :
"I have a question about "USB FM TRANSMITTER": Will it work with Apple Macs? "
Keene replied: As far as we knwo this only works with a PC
28 Rik S on 24 Jun 2010 asked :
"I have a question about "USB FM TRANSMITTER". Can this be used as an audio sender in the sense that I want the PC to play from its speakers, and also send an FM signal to somewhere else in the house. If this is like a normal sound card that would imply you can only have one active at a time and so cant listen and send at the same time, unless there is some special software. thanks for info."
Keene replied: Hi, It installs on the computer as another sound card so you can choose between them but unfortunately you can't use both at the same time. Many thanks
29 Philip B on 11 May 2010 asked :
" Is the FM frequency fixed or selectable?"
Keene replied: The frequency range is listed on the spec but here it is again:- Frequency range: 87.5 - 108MHz Power: 50nW
30 Yiannis H on 11 May 2010 asked :
"What is the range (distance between PC and radio) of the device "
Keene replied: This is very difficult to answer as various factors can effect the range. The sensitivity of the radio, the signal strength, how many walls it is going through , thickest of the walls etc. The range will be limited like other wireless senders and all above factors can play a part.
31 Peter S on 11 May 2010 asked :
"I have a question about \"USB FM TRANSMITTER\". Can you please tell me what sort of range to expect. Thanks you"
Keene replied: This is very difficult to answer as various factors can effect the range. The sensitivity of the radio, the signal strength, how many walls it is going through , thickness of the walls etc. The range will be limited like other wireless senders and all above factors can play a part.
