How long can you record a radio programme with a GB SD card?

The recording time for a radio program on a 1 GB SD card depends on the audio quality and format. For example, if you record in MP3 format at a bitrate of 128 kbps, you might get around 8 hours of audio. Higher bitrates or different formats will reduce the recording time. Always check the specifics of your recording device and settings for more accurate estimates.
