Malachit" SDR receiver, anyone have any experience with the original or more to my interest, the Chinese clone(s)?? This link has info on the Russian design itself. https://www.qsl.net/n9ewo/malahit.html The Chicoms have an assorted range of prices and packages for what they offer. The cheapest ones seem to be a reasonable and fast way to get a portable radio WITH a spectrum display, useful for many things, including finding digital noise... might suffice for other uses as well. ANYONE BUY OR USE ONE?? _-_-bear PS. searched here and found no mention!
