Sorry for inconvenience, please can reported spots for ZS6CNP for UTC period 2017-07-01 17:46 till 2017-07-01 18:06 be removed.
The TX power output of our QRP-LAB shield was found to be much higher than the WSPR message value of 23dBm (200mW).
TX power was lowered at UTC 18:08.
ZS6CNP and myself are finalizing this WSPR beacon project and debugging for possible errors in Arduino code and maybe hardware.
