We are a distributor for Airspy through their manufacturer, ITEAD. In fact, we are the exclusive distributor for the USA and Canada. Airspy.com is the author’s website. Airspy.US is the domain we acquired in order to promote our USA distributorship of Airspy products. It is likely the easiest domain to remember for such a venture, and the more easily remembered, the better choice it is. It was between Airspy.US and ComeheretobuythebestSDR.com. It was a difficult choice, but one we feel we made correctly.
