This is a 32-bit application, written in 100% assembly. It supports Duo and 1A, is known to run under 64-bit Windows 10 and 32-bit Windows XP, and presumed to run under all versions in between. How it reacts to awful Windows 11 is unknown. It was created to compare the capabilities of the SDR to high-end analog scanning receivers, not as a commercial-grade product. Nevertheless, it is functional and useful as Windows PC-based scanner in my radio monitoring environment. Maybe it has some use for others. Maybe not. Just in case, how do I get it added to the list?
