Former student Luke Barnes showed a group from Bath College around Somer Valley FM.
Students studying Level 3 IT visited the radio station in Midsomer Norton to take a look at IT facilities.
They listened to a presentation about running a radio station and the legal requirements of broadcasting.
Students tested software used to program broadcasts and learnt how the radio station backs up its programmes every day.
Mr Barnes, the radio station’s production and systems manager, also introduced students to station manager Dom Chambers.
Somer Valley FM is a non-profit organisation and all income is invested back into the radio station to keep it running.
Students talked about volunteering at the radio station, which only has two full-time members of staff and relies on hundreds of volunteers.
Lecturer David Wills said: “This trip demonstrated to students the high degree of enterprise needed by staff to found and run a local SME company on a non-profit basis.
“The experience was appreciated by students as it gave them an insight into different range of possibilities for work placements and a chance to talk to enthusiastic entrepreneurs who are local and accessible.”
