KLZ was initially located at Reynolds' home at 1124 South University Boulevard in Denver. Two 80 foot (25 meter) towers had been erected, one in front of the house and the other behind, to support a large "flat-top" transmitting antenna and counterpoise. A room in the house was set aside as a studio and also housed the station's transmitter. Initially Reynolds — who played saxophone and violin — and his wife Naomi — who played piano — provided much of the entertainment, and they were later joined by their young son. KLZ's studios later moved to the Shirley-Savoy Hotel, with the station antenna constructed atop the building.
