V/UHF Log 2001/08/22(WED)

Typhoon is running near Tokyo today. The tropo. conditions on FM bc band were very bad, even stations in Sendai (approx. 160km) were weak.

In the morning, a small Es opening. JA6YBR/b faded in at 0721, till about 13 o'clock. According the ionosphere data, so-so strong Es had ouucrred above Tokyo around 12. I could hear JA2IGY/b from 1150 to about 13 o'clock but it is not so strong. I could not hear any other stations.

In the evening, F was fairly strong though I colud not catch any Australian and Thai stations. JA6YBR/b again. I saw a few reports of JA1--Okinawa on 50MHz.

Several Australian FM bc stations were caught in JA6 again. The spread F is still at far away, the F above Okinawa was not spreaded today.

台風が近づいているせいなのか,FM 放送のコンディションは最悪で, FM 仙台もかなり弱い状態になっていた.  午前中は宮崎ビーコンが断続的に聞こえていた. 昼過ぎは伊勢ビーコンも聞こえていたが,あまり強くはなく, ほかには何も聞けなかった. この時間帯,東京の上空に強い Es が発生している.
 夕方 F 層はまあまあの強さだったが, あまりダイヤルを回さなかったこともあり, オーストラリアやタイ TV は受信できなかった. 宮崎ビーコンも再び断続的に聞こえ, 50MHz では東京〜沖縄間が軽くオープンしたそうだ.
 20時を過ぎて九州ではオーストラリア FM がきのうに続いて聞こえたという. 沖縄上空の電離層データではスプレッド F は見えていない.

The Ionosphere

No strong Es occurred at Okinawa and Wakkanai.
