Review of SDR Hardware for the Personal Space Weather Station

This presentation is a survey of currently available SDR receivers for HF use, focusing on devices aimed at the amateur radio and experimenter community at a price point of $1000 or less.  That scope includes a lot of commercially-available radios, and it is the goal of this presentation to gather information about the characteristics of each device that are relevant to the HAMSCI requirements: frequency range; dynamic range; frequency control; possibility to timestamp samples; IQ streaming capability, and openness of development platform.  Where applicable, additional interesting features of the devices are noted. While primarily focused on HF receivers, transceivers and units with higher frequency coverage are included where they also provide useful HF receive performance.
