I spent a few hours on making FM Radio of my H300 fitting my optionion :)
This patch is coded not with much attention to the coding rules, so no use of langfiles and some other not very fine things.
Range from 1MHz to nearly 134MHz. Frequencyrange is selectable in radio menu.
Frequencysteps: 8192, 32768, 50000, 100000, 500000 HZ for fast and for fine tuning (8192Hz is minimum step for tea5767)
Highside/Lowsideinjection can be chosen via menu to remove noise of unwanted stations... mostly works for me :) (code works but effect is not always there)
And finally the thing i coded first, some weeks ago and which is VERY unstable (not really unstable, but not really good working):
signalstrength indicator with "Softwaremute". When strength drops below 1, volume is decreased by 0/10/15/20, if it raises above 2 volume is increased same value. Set it to 0 for off. I recommend the Off-setting because it doesnt really work and consumes some CPU power (->+ more noise because you hear every cpuactivity in the radio). The signalstrengthindicator is then also off.
Why did I code this?
a) the german "CB-Funk" around 27MHz works fine :)
b) flight-radio, 108-133MHz is fine also ^^ Well, it is AM so you HAVE noise while listening, but it is okay.
