The FM transmitter on the Nokia N900 is one of my favourite features. The N900 was not the first Nokia to have it but the first to actually have a usable one. This was because you could boost the FM transmitter output and thus get clear sound even in slightly congested airwaves.
But in a city like Dubai or LA, its virtually impossible to get a station where there is no interference from other air waves and this makes the FM transmitter much less useful. But as with most of the N900′s other features, there’s a mod to make it even better and a simple hack can make the N900′s FM transmitter broadcast at anything between the 76.0Mhz – 107.9Mhz range. This means that you can go below the N900′s default 88 Mhz and easily find a clear station as there are no FM stations broadcasting at under 88 Mhz due to government regulations and other reasons. All you need is a FM tuner that supports these frequencies.
Here is how to perform the mod:
- The first thing you need to do is uninstall the FM Boost and FM Transmitter Widget if you have them installed. Also install any other app/widget that interacts with the FM transmitter. The reason I recommend doing it is because from what I have read, some users have had problems. For the majority it shouldn’t matter.
- Next, download this file, unzip it and transfer it to the N900. Make sure you keep in on the N900′s internal storage and not inside any folder.
- Open the Terminal and enter ‘sudo gainroot‘ without the quotes. If you do not have ‘rootsh’ installed, install it from the Application Manager before you enter this command.
- Next enter ‘cd /home/user/MyDocs/‘.
- Now enter ‘mv fmtxd /usr/sbin/‘. If you want to backup your default files first, use ‘mv /usr/sbin/fmtxd /usr/sbin/fmtxd_old‘.
- Followed by ‘cd /usr/sbin/‘.
- Then ‘chmod +x fmtxd‘.
- Finally ‘fmtxd -d‘.
- Now close the terminal.
- Now open the Application Manger and install an app called ‘FMTX Faker’.
- You will find it in the ‘Settings’ menu. Open it and confirm.
That’s it, the FM transmitter on your N900 can now broadcast at anything between 76.0Mhz – 107.9Mhz and the power is also boosted to 120 so you will not need the FM Boost application anymore. The N900 just became more awesome. Follow this TMO thread for more. Original hack by Jake Kowski.
PS: Please undertake the above at your own risk. It may also be illegal to use the above frequencies in your country. You have been warned.
