JHBB 1926 Japan

 

Article from Dec. 1926 QST

 

In the 1920's, JHBB was the call-sign of an early experimental short-wave radio station in Hiraiso, Ibaraki prefecture, Japan. The operators experimented with wireless telephony and broadcasting. Transmission tests were regularly broadcasted on short-wave in phone and CW. Reception reports were greatly appreciated. They also tried to make two-way QSOs with other radio amateurs worldwide.

On the other end, the brothers
Howard C. Seefred (6EA, u-6EA, W6EA) and Lyndon F. Seefred (6EB, u-6EB, W6EB) were early amateur radio operators in Los Angeles, California, likewise experimenting on short-wave and especially interested in listening and transmitting to remote stations and trying to achieve always new long distance records by wireless communication.

The brothers also knew about JHBB and did not only try to pick up the transmissions from Japan, but were also interested to know whether their own transmissions could be copied in Japan.

The depicted JHBB QSL card confirms the reception of a wireless transmission by Lyndon (u-6EB) on Oct. 19, 1926. The wording "Yes hr hrd u once" indicates that Lyndon was the initiator of this communication by mail.

The QSL card was postmarked on the "15 12 22" (in the "YY MM DD" format), which corresponds to the date of "22 December 1926" (=the 15th year of the Emperor Taisho whose era started in 1912 and who died just three days after this card had been mailed).

From these early Amateur Radio activities by JHBB the original QSL portfolio which contains many QSL cards and letters of radio amateurs and short-wave listeners from all over the world has survived, and also a notebook in which the correspondence with these radio amateurs was captured by date, with entries from July 1926 (Taisho 15) until June 1928 (Showa 3). All these documents are accessible for the public on a Japanese website (Link:
http://hp.jpn.org/JR1YPU/JHBB-QSL).

This website also provides the links to the original documents from both Seefred brothers. There is Lyndon's (u-6EB) letter of Nov. 21, 1926 to J-JHBB (Link:
http://hp.jpn.org/JR1YPU/JHBB-QSL/16-01.jpg), in which he wrote how he had heard the CW signals of JHBB on Nov. 3, 1926. He expressed his hopes to "qso" JHBB "some time", and then asked: "Have you ever heard me?". After a short description of his station he asked to send him "a description or photo" of the station, and he promised to do the same.

The correspondence book of JHBB has one entry for u-6EB under the date of "15.12.20" which is the 20 December 1926 (Link:
http://hp.jpn.org/JR1YPU/JHBB-QSL/00-02.jpg), just 2 days before the depicted QSL card of JHBB was postmarked. Therefore it can be safely assumed that this QSL card was sent in response to Lyndon's letter and that it gave definitely the answer to his question whether JHBB had ever heard him. Indeed he had.

The website also provides a link to a QSL card from his brother Howard C. Seefred (nu-6EA), on which he reported that he heard the "voice" of JHBB on 40m on Nov. 27, 1926, and asked for a confirmation of his reception report with a card, because, as he stated: "This is the greatest distance I have ever heard a radio telephone".
