The report presents both the traditional channel modeling statistics (consecutive error distributions and gap-distributions), and a set of new statistics against which modeling can be performed. The error statistics incurred in the transmission of high frequency digital data at rates of from 600 to 2400 bits per second over various paths of the Eastern Test Range are presented herein. The data was transmitted on and parallel to the range using various modulation systems (modems). It is demonstrated that the errors occur in non-random fashion and in some cases are periodic. These error patterns (especially the periodic ones) present a new, important problem for channel modeling of HF data from a heavily-used transequatorial circuit. With these statistics, those not having direct access to the data will be able to tackle the problem of modeling this data which doesn't fit any known model (e.g., Gilbert, Berkovits, and Pareto).
