Hi all. The photo is a signet which my grandfather have engraved on 1930s; meaning busy, breed, augment or prosper -- I am sharing this particular Kanji, 'Han' with the grandpa.
I am especially interested in 50 MHz propagation/DX and the system-up for this purpose. I am using home brew made transverter + hb 1-kW output legal linear amp, into 2x10.7m boom 8-element Yagis 7.7m apart, at 30m AGL, with an hb elevation rotator mechanism.
With this system I have accomplished the EVER FIRST 50 MHz EME QSO from Japan/Zone 25/Asia with Ray WA4NJP. I specially thank to Ray, who have done a maintenance of the driving motor on the mast at the most harsh winter season for our sked!
Are you enjoying your radio amateur life? Please be aware that we are surrounded by the universe - and many natural phenomena. Our propagation is much affected by the activity of the Sun 150,000,000 km apart. We are jammed by the cosmic noise from many noise sources including Sagittarius-A where scientists say the largest black hole in the center of our galaxy at about 30,000 light years apart from us.
Just doing 59(9) QSL!? style QSOs? You can not earn more DX without knowing the nature of the propagation and other basic scientific facts. We have great opportunities to learn natural science through our amateur radio experience. Conversely our radio experienses are closely connected to, not only electronics, but also the natural sciense. There are many facts left unknown.
==== about the SSSP ====
I have discovered the SSSP - Summer Solstice Short-path Propagation. The SSSP have never been reported on 28 MHz nor 144 MHz - it is the propagation specifically to our six meter band.
From the end of May to the middle of August I am calling CQ every day on six meter to collect data of the propagation. On 2008 season I worked 50 QSOs with EUs and 456 QSOs with NAs including HI3, VEs, XEs and KL7s on six-meter via the SSSP from Chiba Japan.
I wrote an article regarding the SSSP for some Six-Meter News in English. I also specially thank to Chris G3WOS who have edited the article. If you need the article please send an email to me. I can send a pdf version of the article.
==== News ====
My activities around the summer solstice season have been introduced on the world above 50MHz column, QST September 2008.
The above mentioned SSSP article has been published on the Fall 2008 issue of the CQ VHF magazine, with a comment titled "Long-Range Summer 6-Meter Paths Between The U.S. and Japan" by Ken WB2AMU.
==== 50MHz SSSP QSO results ====
as of August 13 2008: 50 QSOs with EU, and 456 QSOs with NAs.
as of August 13 2009: 105 QSOs with EU, and 262 QSOs with NAs.
as of August 12 2010: 130 QSOs with EU, and 196 QSOs with NAs.(preliminary)
==== about the ARRL LoTW ====
Now I have partially adressed to the ARRL LoTW: please let me know if you need a confirmation with this way.
Thanks for reading, de Han JE1BMJ QM05BR
Also thanks to the Chief and all of the Staffs of the QRZ dot com.
