That is also one of the reasons why nobody would be able to trace you, the signals is simply too weak!

You don't even imagine how much interference you can get from one small 50nW transmitter in place where signal is weak - you can interfere with radios in ~100m radius with a bit of luck.

Triangulating signal from transmitter like that is quite easy - there are ready systems for this purpose located around bigger cities, and can locate signals instantly (and such systems has existed for 70 years - http://en.wikipedia.org/wiki/Elephant_Cage) so it's illegal and easy to locate

FM transmitting + Bluetooth headset is working together nicely, when you recieving a call it will switch back to bluetooth headset and once you've ended the call then it will redirect back to FM Transmitter.

This is a GO GO not NO GO! Safety comes first my friend.

For the sake of others:

1. Uninstall fmboost, simple fmtransmitter widet.. etc
2. Download and transfer to N900, the fmtxd file from the zip file attached to the first post.
3. x-term > sudo gainroot
4. cd /home/user/MyDocs/
5. mv fmtxd /usr/sbin/
6. cd /usr/sbin/
7. chmod +x fmtxd
8. fmtxd -d
9. close xterm
10. Open app manger and install fm faker.
10. Open fm transmitter from settings and confirm.

Please let me know if there are any errors.

Thanks

thanks for this. much easier. i have changed some of it and works like a charm now!

Step by step guide:
===========================
Before starting:
Assuming you've got none of these installed:

*FM-Boost
*Simple-FMTX-widget
*FM-Faker
*And FM-Transmitter is turned off
*Extras-Devel Repository is enabled. Then proceed the following

1. Download and transfer to N900, the fmtxd file from the zip file attached to the first post.
2. Uninstall fm-boost, simpleifmtx-widet.. etc,

open xterm
sudo gainroot
apt-get remove fm-boost simple-fmtx-widget

4. go to MyDocs folder where you saved the fmtxd file,

cd /home/user/MyDocs/

5. Move the file to replace the current one,

mv fmtxd /usr/sbin/

6. Go to where the file has been moved, and use the following commands:

cd /usr/sbin/
chmod +x fmtxd
fmtxd -d

7. Now reinstall the fm-faker and simple-fmtx-widget

apt-get install fm-faker simple-fmtx-widget

8. Leave xterm open

9. Go to your FM-transmitter and check if your range has been change. Enable it and then try to disable it. You'll get "Unable

to use FM transmitter". Because of the standard app doesn't know the frequency range in the modified fmtxd . Don't panic it will

be fixed later. Just check to be sure you can see the new frequencies.

9. Go back to Xterm and type the following:

chmod +x /usr/sbin/fmtxd
killall fmtxd
fmtxd -d (this will restart the FM transmitter daemon)

10. If the transmitter still does not shut down, then go back to xterm and type:

reboot

11. After reboot, your fmtx widget should work fine and so should the settings in the settings menu.

I believe someone will come up with a hack but I would just bluetooth and then FM it

lol...i work from home and just find my bride!

i would rather not be bothered and have it go straight through to control the volume and not have multiple units going.

i used a motorola t505 for a long time which would allow me to use my car speakers for my calls. it worked great. just not sure why this was blocked. would still like the hack to be done if anyone is willing to break it.

I believe because of the feed back received from the speakers would interfaring with the converstation and echoing. You can hear them but they will hear themselves talking while talking and listening. Very confusing isn't it!

Thought I would just say for definite...

My FM transmitter using that new file WORKS WITHOUT FMTX-FAKER.

Just put it on 87.5mhz and turned it on without a problem, and listened to it on the radio

Yeah some people got it to work without FM-faker, not sure why but if you get the "Unable to use FM transmitter" then you need FM-faker

to trigger the FM Transmitter to work again. More like a shock to revive a dying patient.

of course rules and regulations might be less tight but if you have to serve time in jail if you order orchids abroad and sell them.....

will you cover every aspect(legal fees, fines, ...) if someone using this gets caught and gets fined for example?

if not, why are you engouraging people to do something you don't seem to know a lot then?

can we just stop engouraging and say that everyone does it with their own riks. You probably won't get caught anyway but one probably doesn't win in the lottery too....
