Method summary

For my QTH, only the 20-meter band at 15 UTC is suitable. This time the signal was not bad, with slight QSB. Overall, I hope for a good result in the measurements of the fifth round. This time the post-analysis took me about four hours of thinking...

Method summary

Using KiwiSDR because I could not receive even a hint of your 20M transmission in Virginia (USA). Analyzing recorded data using Spectrum Lab and SCILAB tools as well as Sound Forge. Set VFO B on kiwi to RWM to get PPS reference. I have no characterization of the kiwi but I think I have good results. It is nice to have a signal not buried in the noise by 40 dB. Thank you for running this. It's always a challenge. This time a completely new one by having to use a kiwi.
