arduino_si5351_cw_beacon

auto-calibrated-gps-rtc-si5351a-fst4w-and-wspr-mept

This Manned Experimental Propagation Transmitter (MEPT) uses the very popular Arduino Nano and Si5351A clock generator board to generate LF – 10 meter FST4W or WSPR signals. Frequency and time accuracy are maintained by a highly accurate temperature compensated DS3231 real time clock (RTC) board or by using a GPS receiver.
