For field operators using high frequency radio systems, two-way communication is never guaranteed. Antenna design, height and configuration, radio power output, interference from nearby electrical equipment, as well as environmental conditions such as lightening, the position of the sun and even the solar cycle can all have an affect on the reliability of HF radio […]
