The Excalibur came with a 12VDC linear power supply, a proprietary USB cable and an SMA-to-BNC adapter, rather fragile in appearance in fact. Surely, nobody uses SMA connectors for their HF receivers??? A comprehensive (107 pages in fact) user's guide, based on the Excalibur software help function was also enclosed.
The hardware is more or less identical to the other Winradio receivers. The footprint roughly equals that of the Perseus SDR, but slightly taller.
As I learn more about the receiver I will post some theme-based impressions on the blog. More as it happens.
