Making my DX log on Google Maps

     I have participated in MW DX expeditions in Japan with many DXers since 1996. I 've recorded the all received MW signals into SDR files but unfortunately, I didn't have enough time to analyze them. I think it would be worth for my DX records to visualize each received station on a world atlas because the location distribution of received stations is easily grasped at a glance.
     Here is the link to my DX log on Google maps.  This is still under construction but I will add my past MW DX logs on this map as possible as I can during this summer vacation. You can click one of the small icons of my received stations then you can see the log data and the clickable link to audio or video file of each station.

  1996年より、多くの中波DXerの方々と中波DXペディションに参加してきました。それぞれのペディションで受信した信号は全てSDRのファイルとして保存していますが、解析している時間が十分に取れていないのが実情です。自分が受信した中波DX局を地図上にマッピングすることはその受信局のロケーションの分布等が一目でわかるので有益だと思っています。
 私の受信ログをグーグルマップにマッピングしたものを公開します。まだ自分が受信した全局はプロットできていませんが、この夏休み中に過去の受信局を出来るだけ加えてみようと画策しているところです。地図上の受信局の小さいアイコンをクリックすると、左側にログデータとオーディオあるいはビデオへのリンクを参照することができます。オーディオあるいはビデオへのリンクはクリックしていただくと、受信した時の状況の受信音等を聴くことが可能です。

TDXC Journal "PROPAGATION" Vol.6

   I had been very busy with my work and I didn't update my blog for about one year!!  I am a member of TDXC (Totsuka DXers Circle) and I had been concentrating on some articles for TDXC annual journal "Propagation" Vol.6 since this May.
  I posted 3 articles. The first one is Interview with a Canadian DXer Mr. Nick Hall-Patch who visited Japan and joined our MW DX expeditions in Nigata and Kiritappu in Hokkaido. The second one is A prediction method of electric field strength and reception CN ratio for TP-DXing on MW band by ITU-R P.1147-4 and P.372-13.  The third one is a report of a radio wave school for high school students in which I taught them some attractions of radio waves.
 This edition is written in Japanese for most of the parts but some articles are written in English including the index. So I hope you can imagine what is wrote about in this journal.  We are the same enthusiasts of SWL and MW DXing so I believe you can easily understand our journal ;-) .

You can download this journal here. (Please click "here". ) Since this morning, Because of too many accesses to the server, you might not be able to download the journal for a while. In that case, please try to download it a little later.

TDXC Journal "PROPAGATION" Vol.5 has been released!

    Unfortunately, I'm afraid to say the population of enthusiastic fans of SW DX and MW DX etc. has been shrinking here in Japan. However, some Japanese DXer groups are still conducting their activities enthusiastically with cutting edge DXing techniques for all bands.
    Let me introduce one of nice Japanese DXing groups to my foreign guests who visited to my blogs. The Totsuka DXers Circle (TDXC) has published its annual journal called "PROPAGATION" every August since 2013. Most of articles are written in Japanese but you can understand or imagine what is written about in each page if you are a DXer too. Many topics related to DXing are condensed in each article :) You can download them "free" from the TDXC representative Hiroo Nakagawa's HP(http://my-bcl-life.sakura.ne.jp/PROPAGATION.htm). I have joined this group since 2016 and I could contribute articles for the journal of Edition 4 and 5.
    At the first glance, you eyes would be grabbed by a beautiful Ukiyoe-like illustration in the front page of the journal. These fabulous pictures can depicts that these magazine are published from Japanese DXers.  One of TDXC members, Shinya Hasegawa who is a professional animator draws these wonderful pictures.
   To dear foreign DXers,  any comments regarding to these journals are welcome.  We have enjoyed broadcasting DXing each other even though we live in different countries.  We have experienced trans-national understanding through listening SW, MW-DX stations.  We can easily communicate each other with Internet in this wonderful era.  Why don't we exchange our wonderful DXing experiences ?
