4 JohnMcPherson 5 !Tuning/Listening to the radio
3 StuartYeates 6 You can use the "radio" application to tune and listen to radio stations. This is part of the xawtv(1) package, but in [Debian] at least it is split into its own binary package:
7 JohnMcPherson 7 <verbatim>
3 StuartYeates 8 apt-get install radio
7 JohnMcPherson 9 </verbatim>
3 StuartYeates 10
11 Here is a sample __~/.radio__ configuration file for it (based on Hamilton frequencies):

3 StuartYeates 41 Gnome Radio is a nice gui for [GTK2] that can store frequencies and record streams onto disk as Wav, [MP3] or OggVorbis.%%%
42 RedHat users with Dags repo set up on Apt or yum can install `gnomeradio`

45 !Recording
46
47 1. Use the Gnome Radio program as above.
48
49 2. From the command line:
50
51 Step 1 - (Make sure your sound card's mixer is set to record from the appropriate device - eg from Line In if you are using a loop-back cable).
52
53 Step 2 - run the "radio" command or whatever program you use to get output to the sound card.
54
55 Step 3 - run the following commands (or put them in a script and run that). Press Ctrl-C to finish.

4 JohnMcPherson 77 ----
78 Note that these commands aren't really radio-specific - they could be
79 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.

82 !!! Troubleshooting
7 JohnMcPherson 83 !!UDev
84 [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.
85
86 To tell udev to create a symlink, create a file called 00_video4linux.rules
87 in the /etc/udev/rules.d directory, with the following content:
88 <verbatim>
89 # make a symlink to the first radio device
90 KERNEL="radio0", SYMLINK="radio"
91 </verbatim>

94 !!Misc
6 JohnMcPherson 95 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.
10 JakubHozak 96
97 !!Kernel parameters
98 There is an insmod parameter for saa7134 "radio_nr" that specifies the number of radion device and ther is probably no "radio" flag parameter,
99 by which you can turn the support on/off (use modinfo for more info). But if you want to use a radio and your doesn't have an EEPROM, you must
100 set the "card" parameter explicitly and the board you set MUST have a builtin radion. Otherwise the radio just won't play, and no error message
101 appears.
