The study involves both selection bias and participation bias. Selection bias occurs because the sample is not representative of the general population; it only includes people who listen to that particular radio show and are motivated enough to respond. Participation bias is present because the respondents chose to participate, which may indicate they have stronger opinions on the subject than the general population.
