Many TvTunerCards have a radio tuner built in.
!Tuning/Listening to the radio
You can use the "radio" application to tune and listen to radio stations. This is part of the xawtv package, but in [Debian] at least it is split into its own binary package:
+<verbatim>
apt-get install radio
+</verbatim>
Here is a sample __~/.radio__ configuration file for it (based on Hamilton frequencies):
+<verbatim>
# frequencies have 6 decimal places of precision?!
[[Stations]
# 91.4

Gnome Radio is a nice gui for [GTK2] that can store frequencies and record streams onto disk as Wav, [MP3] or OggVorbis.%%%
RedHat users with Dags repo set up on Apt or yum can install `gnomeradio`

Step 2 - run the "radio" command or whatever program you use to get output to the sound card.
Step 3 - run the following commands (or put them in a script and run that). Press Ctrl-C to finish.

Note that these commands aren't really radio-specific - they could be
used for recording anything, although the settings here are ok for radio-quality audio. Also, if you use [ALSA] then you will need to have [OSS]-emulation drivers loaded.

+!!UDev
+[UDev] by default (at least in Debian and Ubuntu) doesn't create a symlink for /dev/radio (to /dev/radio0), but the 'radio' program tries to use /dev/radio.
+
+To tell udev to create a symlink, create a file called 00_video4linux.rules
+in the /etc/udev/rules.d directory, with the following content:
+<verbatim>
+# make a symlink to the first radio device
+KERNEL="radio0", SYMLINK="radio"
+</verbatim>

The driver for the radio tuner on the saa7134 tv tuner card seemed to have been broken for LinuxKernel 2.6.8, but works again in 2.6.9.
