Radio without ads, paid for by the people who listen.
We have no corporate owner. Rent, electricity, the transmitter on Mount Lemmon and the insurance on the studio are covered by members, small donations and a handful of local underwriters.

Underwriting rates
Underwriting is a short, truthful message read by the host, with no price claims or calls to action. We turn down advertisers who do not fit our values.
