I just searched from 87.5 to 108 at extensive scan and i got only 21 empty frequencies. Only 10% of the range i scanned was empty frequencies. Btw you are right that the reciever of n900 isnt that sensitive, I hope that t-control will scan better using the transmitter instead of the reciever.

yeah I know as the headphones act like an antenna... but on a lot of frequencies the n900 is empty, there may be some noise on car radios, as they seem to amplify the radio signals better and from radio stations farther away.

And I guess that different headphones (with different shielding and cable length) probably also affect the reception and scanning results, right?

Mhm... With eff 0.9.2 I found more than 100 free frequencies on extensive search. While I'm writing I'm trying again with 0.9.3 and some headphones with a 2m cable in a straight line on my bed.

Btw. is it possible to broaden the frequency range to scan from 76MHz to 108 as I have unlocked them with the modified fmtxd.



========
One more Edit:
Ok scan has finished and it found 116 free freqs, thats 56% of the scanned freqs. What's weird is that it doesn't include a frequency that I've found manually while sitting in my car and searching for empty freqs. I still prefer to use this frequency up to today as it is still more noise free than I've tried from the results of eff.

I guess that eff scans every frequency for a more or less strong signal. But it seems that alot of "unused" and empty frequencies have noise from interferences.

dude, why did you name the package the exact same thing, now the one in the repository wants to overwrite it and drives me nuts. I have to make an apt preferences file to block it...
why don't you rename it to EFF-GUI or something and just put a Conflicts: or Replaces: line in the control file?
oh, and fyi, the link to this thread in your sig is messed up.

dude.. thanks a lot for ur kind effort..
i've installed it, but couldn't find it in the apps menu!
any conditions to run this app?

another point... normally, it's not possible to run the FM transmitter while the headset connected, so how it'll act as antenna?

thx a lot..

* Uninstall the version you cant find in the menu
* Install the deb version which is available on the first post of this thread
* Dont update with the (shell script) version availbale in the repos.

I didnt understand your second question. E.F.F. just uses the headphones as antenna and turns on the reciever to scan for empty frequencies (in extensive mode searches for the emptiest frequencies possible using the reciever and fm_rssi file). E.F.F. has nothing to do with the FM Transmitter.

This gives me an error "cant find fm_rssi"

Edit: Couldn't get the one on the repos to work either
Running with command: EFF did the job to run the script from the terminal.

great and useful app. many thanks

There is a slight problem with it. frequency signal reception differs from radio to radio. eg I get no signal from N900 on 93.0 fm but I get signal on an ericsson phone at 93.0 fm. since the empty signal should be on the receiving radio and not the transmitting (n900) it's a bit of a problem here.
I have scanned the all frequencies and I found 7 empty with e.f.f. on another radio these frequencies were not "completely" empty. only one of them had a little hissing noise.
I don't know what will happen with my car radio as I have not yet tested it and I am sure it has a very good reception.
