Yes, many radio shows are available as podcasts. However, some are not. If a radio show is also broadcasted via a live stream online, then we could record it with streamripper. I did so as follow:
sudo apt-get install streamripper ## install ## record for 60 seconds streamripper http://kpcclive1.publicradio.org:80/ -s -l 60 -a "Prarie - %d"
To have the show be recorded automatically, first create
#! /bin/bash ## set in crontab: ## 59 17 * * 6 /path/to/record.sh cd /path/to/save/; streamripper http://kpcclive1.publicradio.org:80/ -s -l 3720 -a "Prarie - %d" &> /dev/null
Then add the following cron entry via
59 17 * * 6 /path/to/record.sh
