During longer VarAC chats, there is a considerable amount of valuable SNR data generated by VarAC. Below is an example of a DX QSO today. It was on 20m during the long-path opening from VK3 to USA east. It was just at band opening time and hence the continuous improvement of SNR with time. Irad has now kindly implemented a graph data download option. Can't wait to have that :)
The data can be used for the purpose of comparing different days and for some simple statistical processing & correlations with propagation-relevant data.
