Summary

A radio spectrometer has been designed and constructed for ground-based solar observations in the poorly covered frequency range below 20 MHz. Techniques have been developed to avoid and excise the abundant interfering signals prevalent in this frequency range. The system scans the radio spectrum from 3 to 37 MHz and provides nearly interference-free records of solar radio bursts with three second time resolution, 268 kHz frequency resolution, and a well-calibrated flux density scale. The instrument is normally operated from 2200UT to 0630UT each day.
