I looked at the datasheets for chips used for FM reception, and I don't think this is currently possible. I am posting this because I hope that I am wrong.
Weather Radio is a US/Canada government run service to alert people to bad weather. Weather radios are a push model that the alarm goes off when they recieve a particular signal. A computer generated voice tells your what watch or warning has been issued. Even without that they work in the 162.4 - 162.55 MHz bands, well outside of standard AM or FM. Still, you can buy radios without the alert feature that listen to these bands. That is exactly what I would like my Sansa Fuze to do. Here's the Wikipedia page for Weather Radio for more info:
http://en.wikipedia.org/wiki/Weather_radioI thought it would be handy to have a device that I normally have around me that can listen to those bands during bad weather.
I looked through the git under [rockbox.git]/firmware/drivers/tuner/ and found the serial numbers of tuner chips supported. I looked up the datasheets and only found mentions to FM and AM bands. Therefore, I determined that from the spec that this is probably not possible in current supported media players.
I live in a place that frequently has tornado activity.
I think it is a neat feature. Anyway, am I right or am I wrong about being able to support this with current players?
Thank you,
