Consideration of surface of the moon reflection communication of 50MHz
October 26, 2008
Hideki Koga
The surface of the moon reflection communication is ..ultimate communication of amateur radio operator.. ..saying... (Is it said?)
Certainly, it is advanced, and is a factor that needing the superlative
degree in the license also raises the difficulty technically.
However, the
surface of the moon reflection communication of 50MHz belt that uses the WSJT
software (Thereafter, it is shown 6mEME) is like the different thing.
If how much equipment existed, it thought whether 6mEME was possible.
After challenging 6mEME that used WSJT in May, 2005 first, the QSO
doing and the number of total QSO will make 126 succeed with 57 games by
present.
Because the number of samples exceeded 100, it is consideration
of my own way.
My equipment has changed from the horizontal stack of Yagi 8 ele to 2 row 2 steps of present Yagi 8 ele.
Then, each QSO results etc. of these
two antennas were compared.

If the other party is five ele Yagi and 1000W output in case
of my equipment, it is understood that 6mEME is possible.
It was able to be deciphered mutually though it did not become
QSO approval as WQ5S of five ele Yagi and 100W output.
6mEME can be easily done with 6-7 ele Yagi and the bureau of
400W.
The bureau more than my equipment is that 6mEME is possible
if there is 200W output in 9-13 ele Yagi or seven Here Yagi stack extent.
It might be a thing with a lot of
desires that EME is impossible if there is no high-power license as seeming the
difficulty, too.
Please do Ticaratame and do try of the equipment of
50MHz of your boast to 6mEME ..possession.. Ken.
Even if it is a Yagi
single that there is a high-power license by five Here, 6mEME is possible.
Mr. W7GJ Lance also says a similar thing and ..
His equipment is Yagi 4x9 ele and 1500W output.
It ..".. ..6mEME.. has not succeeded in four ele Yagi with the bureau
of 100W output.
It might be possible in seven ele Yagi because QSO can do with the bureau
of 100W if there is 300-500W output in four ele Yagi. ｣
Please refer to the homepage of
the following antenna society (reference
1) for a detailed explanation of the surface of the moon reflection.
It is analyzed in the antenna
society of JARL Fukuoka. Reference
