It’s that time of year when Nevada City radio station KVMR 89.5 FM Membership Coordinator Adriana Kelly finds herself a juggler. That’s because the station’s spring membership drive — complete with a spacy “KVMR: Love Your Mothership” theme — starts this coming Monday. Meanwhile, back at the non-commercial Nevada City station, Kelly is hoping to become a volunteer KVMR broadcaster after she completes in-studio training. Oh, and there’s that membership drive phone number — 530/265-9555 — and website –kvmr.org–to help keep new and renewing revenue coming the station’s way. It’s the way to keep these membership staffers — and KVMR’s volunteers — nice and busy the next couple of weeks.
