Abstract

An alternative, or supplemental, approach to automatic link establishment (ALE) radios is to combine modern, commercially available packet radio technology with an understanding of channel requirements to produce a low-cost multimedia radio (MMR). A prototype unit has been demonstrated to provide two-way, half-duplex packetized message communication via skywave propagation when the operating frequency is below the maximum usable frequency (MUF) and meteor burst (MB) propagation when the operating frequency exceeds the MUF. The prototype MMR uses off-the-shelf commercial radio equipment, including packet radio controller, HF transceiver, 1 kW power amplifier (HPA), Yagi antennas, and PC-controller for a total cost below $4000
