Rich K5RWG and I are often testing the 10m path using VarAC. yagi antennas are used on both sides. We use Verbose SNR which is a periodic exchange of SNR reports. VarAC then offers the data as a graph and also a data file. It is fair to say, that the path exists on a daily basis when there is no strong solar wind causing geomagnetic unrest which in turn degrades the ionosphere. Below is an example of this remarkable VarAC DX link.
73 & thanks to Irad for his exceptionally fine work

(at the start we had somewhat misaligned antenna bearings which were corrected quickly)
