These are the only sound files I have of the RCA Theremin. They were done to demonstrate the range as it was with the oscillators restored to specs. I later changed the frequencies of the pitch and reference oscillators to restore playing range.
You can hear spurious oscillations we call “birdies”as the sweep nears the point at which the oscillator locks up and then starts again as we go downscale.
In the second verse of my lousy rendition of “Let Me Call You Sweetheart” You can hear birdies as I get dangerously close to that cutoff point.
The files are a bit noisy but the actual theremin sound was clean. I am sorry for the quality of these recordings. The purpose in making them was to demonstrate my progress as I got her in line.
