all region for the fm radio
TexasRockbox:
Change the channel stepping until "one size fits all". Anolog tuners have an "infinite"number of steps. Some frequency synthesis component Yamaha digital tuners can actually tune in 0.01MHz steps -- suitable for just about any need. I imported a Sony radio from England that tuned in 0.1Mhz steps. No problem, in the USA .1MHz divides into .2MHz with no issue. Whats common between 0.20Mhz, 0.10MHz and 0.075 Mhz? 0.025MHz. Use that step. That method alllows for a bit of off-channel tuning should a neighboring station cause interference.
That's the step that Degen/Grundig uses in their DE1103/G5 radios.
Llorean:
What exactly is so bad about having preset regions?
If a region doesn't cover the whole frequency range in that region, it should be a reason to fix that one region...
lumino:
Extending the whole frequency is something I'm also interested in because of the ATC
I'm a big Flight Sim fan and I'd really love to hear ATC on my radio.
As far as I know, it's actually FM and not AM, and the range is same for the entire world

I think that for rockbox the standard operation should be for a simple FM radio that suits most peoples' needs, for that you need the right regional settings.
If there are regional settings where the tuning range needs (legitimately) extending then raise a bug and if possible supply a patch to fix it.
For folks who want to 'play' there is already a plugin in Flyspray that allows the radio chip in the iRiver H300 (I think) to be driven to its fullest capabilities, including things like step size, and highside injection (whatever that is); http://www.rockbox.org/tracker/task/5448 and apparently allows Airband reception.
I personally thing this is possibly an interesting intellectual exercise but not very useful - a Portable Music Player as too many compromises to board layout, screening (lack of) and antennae design for it to be useful in this mode - but I applaud the developer for having a go!
I don't know if the patch is up to date or what the capabilities for other integrated radio chips are - but that I suggest is where any work should be bone on pushing the radio capabilities beyond the norm for each region.
LurkAzusa:
I don't think that patch is up to date, at all.
How about two more "regions"? An upper range and a lower range. That way we could get the ATC frequencies in the upper range, as well as the TV frequencies in the lower range.
