Homepage von Bernd DL7APV

DL7APV ist mein Amateurfunk Rufzeichen und ich beschäftige mich seit 1983 mit Funkverbindungen auf 432MHz die den Mond als passiven Reflektor nutzen; kurz: EME (Erde-Mond-Erde)

DL7APV is my HAM radio call and my main interest since 1983 is 432MHz EME earth-moon-earth (EME) communication were we use the moon as passive reflector.

Sun noise vs time during the eclipse, theoretical maximum was around 10:45UTC what can be confirmed with the data. The eclipse was about 13,5% here, means about 0,7dB less sun noise what can be confirmed as well. The zigzag line is due to the autotrack and very small main lobe!

The fist peak at 9:15 might be qrm or a sun eruption??




With this antenna it is possible to work EME, with only a dipole!


Give it a try! Like MX0CNS did!




For Skeds drop me a mail to
