Well there isn't many places in the world that all FM channels are used up. But even if you live in one of these rare locations, the strongest channel wins as far as FM goes. And that could be the very little FM transmitter that you are transmitting on since it is so close. Even still, many of these FM transmitters can transmit between channels as well. So it is almost impossible to have a problem with commercial FM transmitters at any rate. I think FM transmitters are the coolest things (well for both video and audio, UHF transmitters are the coolest). As FM receivers are all over the place. Even in your car. As I can hear what is going on driving to and from my own house. Other methods of wireless just can't match the overall usefulness of FM as far as I can tell. Plus FM is very inexpensive while other methods cost a lot more and adds a lot more complexity too. Also I believe I have made it unclear before, but FM is also immune to microwave ovens, cordless phones, garage door openers, WiFi, etc., but Bluetooth is not. Bluetooth is 2.4GHz technology and they are all supposed to get along with each other. But of course reality is far different than on paper. As I have to shift my WiFi channels (2.4GHz technology) so it can work whenever somebody uses the cordless phone (2.4GHz technology). FM transmitters have no such nonsense to play with. As there are no local devices that bothers it at all. I am not saying that Bluetooth doesn't have their uses. Sure the more Bluetooth devices you have, the more attractive it gets. -- Bill Asus EEE PC 8GB 1GB SoDIMM Adata 16GB Windows XP SP2 and Xandros Linux |

Bill, Interesting you are so excited about FM technology. I discovered one aspect of it, when about 15 years, my wife wanted to install a CD player in a car whose radio (remember, that was 15 years ago) had no input port for such a device. My installer proceeded to install an FM adapter, basically the output of the CD player being broadcasted on a (choice of 3)FM frequency. This setup did work nicely in a given area, but in different areas, the choosen frequency could be covered by a radio station. So, I would say, this technology has a lot of merits, but unless there is some automatic frequency matching device, it can be vulnerable to interference. Bluetooth? great but not the way it often is implemented. When I connect my 3G phone via bluetooth to my computer, almost often the OS says "new device found" (even if this is the npth time I connect it) and assigns a new port to the connection (without saying which one). Used to drive me nuts, until I learnt to check the Modem Icon in Control Panel and make sure the port attributed to the phone's modem was the one assigned to the connection. Matching two devices is always difficult. You are being asked for passwords you never wanted, the connection setup procedure is unpredictable. Ok, when it works, dandy. But each connection is an adventure, no big deal for users who know their way out, but for others ... -- John Doue |

I have a Bluetooth mouse for one laptop. The computer finds and connects to
it automatically as soon as Bluetooth is running. They are no problem whatsoever except they won't work until the o/s is loaded. Terry wrote in message ...

Bill, I think Adrian meant, interference due to commercial stations and others. Yeah, depends where you are - but here (London, UK) the FM band is a bit crowded with broadcast stations, pirate (unlicensed) stations, ipod transmitters and hash from badly screened high speed electronics. I take on board the problems with 2.4GHz interference, that can have an detrimental effect (in fact worse than FM if truely bad - bluetooth stutters and cuts out) but when it works it's solid with both RX/TX ends in the same room. I run a busy wifi network here without issues. My solution doesn't dangle a dongle on a laptop for the OP as the hardware is built in. CPU use is not much when you count how many cycles are stolen out of a gigahertz or two. To test this (but going the other way), the OP could make a simple test if he has a mobile phone with bluetooth and stored MP3 files. Pair the phone with the laptop, enable the 'Advanced Audio' service on the laptop and set the phone playing back an MP3 through the link. The music should playback through the mixer and speakers of the laptop. Admittedly, my mention of Skype was a 'curved ball' thrown for advanced use. Some of my machines have multiple sound 'cards' - Skype gets it's own sound card for making calls (and the ringing bell!) while the other sound card is in use with general windows audio applications. -- Adrian C |

Personally, since my mouse in never far away than my machine, I trust an USB mouth, especially since I can use it as soon as my machine boots: convenient to chose the OS I want to boot, with System Commander. Good point I hadn't thought of |
