This will enable dual band (VHF/UHF) operation. Dual ADF7021 for full duplex operation (#define DUPLEX in Config.h) will work only with a big RX/TX frequency separation (5 MHz or more in UHF band for example) and proper antenna filtering. At the moment #define ADF7021_CARRIER_BOARD (Config.h) with STM32F103 platform is supported. Please see [BUILD.md](BUILD.md) for pinout details.
