Supplementary Features
Unit is a scanning hf receiver which scans all 14, 000 3 khz wide channels spaced 2 khz apart between 2-30 mhz; it dwells on each channel long enough to assess the received power level and determine the background noise level; each channel is revisited approximately every 20 seconds; the data thus collected is averaged over either 5 or 30 minutes, and is presented to the operator in a series of crt displays; such channel occupancy data is useful to the frequency manager of an hf system by indicating which frequencies are clear of outside interference
