Receiver: Microtelecom Perseus
Antenna: BCL-LOOP 11
A strong signal was received in the early morning in Japan. The recording includes signing-on, opening announcement, followed by the national anthem of Solomon Islands (very nice song!). It is assumed that this reception was based on the gray-line path, as the signal was gradually getting weaker after sunrise at Solomon Islands area.
Using the data-logging function of Perseus, I plotted the signal strength (in dBm) into a graph, which clearly indicates the propagation getting worse after 0430 JST.
