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 a FTDX-5000mp + hb 1-kW output legal linear amp, into 2x10.7m boom hb 8-element LFA 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 skeds!

Are you enjoying your radio amateur life? Please be aware that we are surrounded by the universe - and many natural phenomena. We have opportunities to have thrilling experiences with amazing phenomena or propagations on-the-air.

 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.

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 experiences - conversely our radio experienses are closely connected to, not only electronics, but also the natural sciense.

There are many unknown phenomena or propagations being left on any amateur bands. If you closely and deeply QRV your favourite band(s) with the best rigs and antenna you can 'discover' new knowledges that other operators did not aware.

It is just like amateur astronomers - they are using small telescopes, digital-cameras and PCs to engage their favourite cosmic objects, while we are using antenna, rigs and PCs for our amateur-radio activities.  

==== 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 early May to 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 have written an article regarding the SSSP for some Six-Meter News in English. I also specially thank to Chris G3WOS who have edited the article. This article is an old version but it can be a help for new commers to get started with this six-meter SSSP propagation.

You can download the SSSP article from here: http://equina.web.fc2.com/sssp0.pdf 

Additionally you can hear some examples of the SSSP QSOs here: https://audioboo.fm/JE1BMJ_Han 

Any questions or notes via e-mail are welcome.

==== 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.

===== FYI: About Japanese Radio-Amateur licenses System =====

One should obtain the radio-amateur operators license first, and then obtain station license with an application to get a permission to operate each of the modes/bands with a callsign for actual operation.
 
The Japanese radio-amateur operators license system has four calasses – 4th, 3rd, 2nd and 1st.
 
The 4th operator class is a no-code, entry-class license and being allowed to operate on phone/digital only; 10-, 14- and 18 MHz bands are not allowed. Operation with 10 W output transmitters on HF and up to 20 W on V/U/SHF bands.
 
The 3rd-class can use all-modes but 10- and 14 MHz are not allowed. Allowed to operate up to 50 W output transmitters.
 
The 2nd-class can use all-modes and bands. Up to 200 W output transmitters are allowed.
 
The 1st-class can use all-modes and bands. Operating power is unlimited, but virtually limited to 1 kW maximum by Japanese radio amateur stations lisence.
 
While the station license up to 200 W is easy to obtain with a simple application procedure, the license above 201 W to 1-kW output stations need a field-inspection of MIC (Ministry of Internal affairs and communications) or its authorized agencies and to pass stringent practical tests at the station’s installation location.
 
Also, there are radio amateur station licenses for ‘fixed’ and ‘mobile’.  Mobile stations are restricted to 50 W maximum output, and those over 51 W are categorized to ‘fixed’ station. Many Japanese hams have both fixed- and mobile station licenses.
 
I have 1st class radio-amateur operator license and a mobile- and a fixed 1-kW output station license. 
 
Integrity and compliance are the Japanese people’s virtues and, obtaining 500 W or 1 kW station license is much easier than ever in the eighty-years of the Japanese amateur-radio history. You can check JA stations' license on the English page bellow:
