Ok ı'm running at 122 now, the device is still alive and running and seems stable, but I wouldn't use it like that for extended periods of time... I just felt naughty, and tbh it wouldn't be of use to me anyway with high noise so I had to do it.
i.e. I'm wondering since the chip specs specify 118, if the driver/chip knows enough to treat any values above 118 as 118.

With each increase in number between 111 to 118, there is a noticeable improvement, but once you reach 118, any higher number doesn't seem to make any difference and sounds the same as 118 itself.

mine is at 114 and works ok in a ford focus
i just wish I could set the freq below 88.1 as everything above 88 seems to be taken
funny enough my region_bottom_freq value is set to 87500 so the 88.1 thing may be a gui limmitation

yes above 118 doesn't seem to make any noticeable difference.
I just wish we could get some more juice out of the radio transmitter as I could really use it

Hi - any of you guys that are looking at these files related to the FM transmitter know if there is anything that enables or disables the transmitter? I might be treading on thin ice here, but I have an N900 from Nokia.co.uk and it currently has the FM transmitter disabled! I'm awaiting a call from Nokia about this - but I was just hoping someone might know of an easy answer - unless of course this is a fault and it says it is disabled because it cannot contact it!?!?
Hmm, anyway, just thought I'd throw that in there. Sorry it isn't directly related - other than asking how I can increase my power from, well.. disabled...

have people covered the fact that the transmitter's digital?
i based this on the fact that when i use my phone in my brand new vehicle, it actually displays "NOKIA" on the car's display, it also has perfect sound quality. but in our 1999 Mazda 626, it doesn't display NOkia, and the sound quality is terrible!

I tried setting it to 118 while transmitting and what a difference! Suddenly so much clearer.
I did find that file /sys/class/i2c-adapter/i2c-2/2-0063/power_level did exist when FM transmitter was off.
I also found that plugging in a wall charger dropped the power level to 88.
Now to make it persistent...
Having a button to press from the desktop while the transmitter is running is a lot easier to do in a moving vehicle where this hack is most useful.
Opening xTerm, entering root, opening notepad, copying the script, then pasting it in xTerm is a bit cumbersome and I do not have the skills to easily confirm that something like:
Code:
[Desktop Entry] Encoding=UTF-8 Version=0.1 Type=Application Terminal=true Name=POW Exec=sudo gainroot Exec=echo 118 > /sys/class/i2c-adapter/i2c-2/2-0063/power_level Icon= #X-Window-Icon=timerwidget X-Window-Icon= X-HildonDesk-ShowInToolbar=true X-Osso-Type=application/x-executable
...in the dark, on a cold rainy night. Brrrrr!

would even work and I would have to run back and forth to my car where my only FM radio lives...Code:[Desktop Entry] Encoding=UTF-8 Version=0.1 Type=Application Terminal=true Name=POW Exec=sudo gainroot Exec=echo 118 > /sys/class/i2c-adapter/i2c-2/2-0063/power_level Icon= #X-Window-Icon=timerwidget X-Window-Icon= X-HildonDesk-ShowInToolbar=true X-Osso-Type=application/x-executable

I am not familiar with the Desktop files that much, so not sure how having to Exec lines works. Is that right?
And as sudo gainroot launches a login shell, any subsequent commands shouldn't run in there, atleast in a shell script it doesn't, again, not familiar with desktop files.
So one could setuid bit on a script that just runs this command, so it runs with root privileges.
Ok I just read your linked thread. That is a command running as normal user. So it gets tricky to escalate privileges in a command.
The setuid is the best I can think of for now, but people will complain it is not a secure option
I need to take a look at that this "gainroot" argument actually does; we might be able to add this command to the suders file so we can simply sudo the command without the need for a password....

I openned up /etc/suders and an excerpt.
So, as root, we can add the command we need and then the script can simply be
This is a quick look, I'll spend some more time on it later..
