At the moment #define ADF7021_CARRIER_BOARD (Config.h) with STM32F103 platform is supported. Please see [BUILD.md](BUILD.md) for pinout details. If you can't decode any 4FSK modulation (DMR, YSF and P25) with your ZUMspot, the common solution is to adjust RX frequency offset (RXOffset) in your MMDVM.ini file. Please try with steps of +-100 Hz until you get low BER. If you don't have test equipment, the only procedure is trial and error. In some cases TXOffset adjustment is also required for proper radio decoding. # Quick start -Please see BUILD.md for more details, and also MMDVM Yahoo Groups.
