FreqEZ is a Do-It-Yourself hardware/software project that provides highly configurable Band Decoding and Remote Antenna Selection. For amateurs who use N1MM+ and DXLab logging software, FreqEZ will leverage those programs TCP/UDP broadcasts for antenna switching. For other amateurs, FreqEZ can connect to the BCD band outputs available from most transceivers. The FreqEZ software and is freely available to all hams, and consists of a pair of programs that run on the Windows and Raspberry Pi Raspbian operating systems.
