legit probably just show up and ask to volunteer or run the graveyard shift or something. If you get the graveyard shift, keep the first and last half hour/hour PG but go wild inbetween. if you stick that out for a bit and they’re legit managing this thing into the ground already, you’ll probably need to be moved to another timeslot after a little while because someone quits or they literally forgot to fill a key slot

also, if this is community radio, they probably have a dono drive/telethon at some point during the year. getting your face out and about and becoming a subscriber/pledger at this time will probably get you noticed tbh
