Evaluation of a Prototype 6 Tone Modem.

Abstract

RAE was asked by 39 Signals Regiment (SC(V)) to evaluate a prototype 6 tone Multi-Frequency Shift Keying (MFSK) modem intended for tactical data transmissions in the High Frequency (HF) band. The main testing was to consist of extensive trials using the RAE Cobbett Hill HF Channel Simulator, but in the event also included some limited live radio trials between Bodo, Northern Norway, and RAE Cobbett Hill in Southern England. The modem performed satisfactorily during the evaluation period and returned good availability figures, both on the simulator, and during the radio trials. (rrh)
