PY2RN WSPR analysis

Bert PA1B has analysed my recent reception on WSPR by PY2RN to see just how little power could have been used and still be successfully decoded in Brazil - the answer is very little for a lot of the time! Most times even 1mW should have been enough. This of course assumes local noise levels allow decoding to the lowest levels for WSPR at around -30dB S/N. In some cases this may not be possible because of local QRN/QRM.

Hello Roger, this table gives the number of spot per hour for a given "calculated lowest possible power" in mW.
The propagation can be seen from day to day over more than 2 weeks. Thank you for posting the table.
