The computer does not need to be running Windows 10, just needs to meet the
requirements for Windows 10.
Minimum requirements are:
Windows 7 or better
Processor: 1 gigahertz (GHz) or faster processor or SoC
RAM:
1 gigabyte (GB) for 32-bit or 2 GB for 64-bit
Hard disk space: 16 GB for 32-bit OS 20 GB for 64-bit OS
Graphics card: DirectX 9 or later with WDDM 1.0 driver
Would prefer a minimum of 4GB RAM as Ham Radio Deluxe 6 requirements state
6GB for 64 bit OS, and a hard drive with room for the operating system and
software.
