Car's audio with RDS active could search for "n900" or "mediabox" if fmtransmiter decides to change frecuence, I'm wrong?
afaik RDS is "downloaded" after tuning into a station, not while automatically tuning. Not sure about it though.

I was thinking about this as well...

I also thought can we use the headphone jack as a means to create better reception for the FM trnasmitter?

Are you thinking of a plug-in FM transmit antenna for the 3.5 jack? That antenna could include an amplifier. If the signal from the transmitter can be moved to the 3.5 jack that would be the end of "the FM transmitter is too weak" complaints.

I'm sure that info is saved somewhere since the transmitter loads to the previous frequency set.
agreed the scanning part will work without the transmitter being enabled, but if the op is wanting to travel round with the transmitter automatically selecting the best frequency, unless the headphone override on the transmitter can be turned off, you'll need to keep plugging in and disconnecting the headphones.

still can't see how the car radio would be retuned. AFAIK, the auto retune works by selecting the strongest signal within a predefined range for a specific station, once a previously free frequency was no longer suitable, a significant change in frequency would be needed, which falls outside the use of auto frequency functions.

this would be great. i use 104.1 here in the bay area most of the time. only run into challenges when i travel.


the ability to tap the screen of a widget and have it "search on demand" and pop up 1-3 freqs to use and then tap that freq should you want to use it, then change your radio station as needed would be awesome.

I still don't understand why so many people have issues with the FM transmitter. With FM Boost enabled I can drive through the middle of the CBD of Sydney and not have the slightest bit of interference

I don't BTW need to go below 88.0 and use a web app if I find I'm a stranger in a strange land and need a new vacant channel.

>> http://www.radio-locator.com/cgi-bin/vacant

>> http://frequencyfinder.org.uk/

>> http://fmchannel.sirius.com/servlet/FMFind

( I found fmchannel.sirius^ not as good as www.radio-locator. YMMV )

With all that^ said... I'm wondering if a 4 or 5 button preset app that launches FMTX set to one of the presets would be more realistic and easier to put together. It could be a status bar app that drops down with the volume slider, Clock & Alarms, Etc.

I think wanting to be weak is actually the reason why transmitter is disabled when there's any antenna substitute plugged in. It might actually become too effective, and there are regulations to follow.

I think we may over think this stuff and come up with reasoning to suit our desire that all behaviors are by design.

Code may have unintended consequences and if these bugs remain unidentified... they never get fixed. Until then, all we can do is cobble together work arounds.

I believe this is a bug based on the fact that if FMTX is invoked while the charger is plugged in, TX power level is unchanged. Unplug the charger and then plug it back in... TX power level goes in the toilet.

If it was designed to eliminate the cable as a possible TX antenna it fails when FMTX is invoked while already on charge or plugged in.

... a bug either way you look at it.

I was thinking for testing purposes only of course we do not want to oversaturate the area around our N900 with illegal, overpowered FM transmissions. If it is that hard to find an empty frequency now, just imagine how tough it would be if your neighbors all put a 1 watt amplifier on their N900.
