134.080GHzで17kmの交信が成立しました!135GHz帯での自己最長記録を更新です!最初に鏡で太陽光を反射させてお互いの場所を確認し、アンテナの方角、仰角を合わせました。 気温18℃、湿度58%、露点7℃でした。短時間でコンディションが変化していたのでタイミングが重要なのですね。

ASML's EUV mirrors made by Zeiss have a surface that is so flat the imperfections are measured on the picometer scale, or a trillionth of a meter. This is equivalent to keeping an area the size of California as flat as a human hair.
