我把JP1LRT的原邮件粘过来,大家一起看看
=====================
Hello. I am a Japanese 6m CRAZY JP1LRT Yoshiharu.
We met on 6m last summer with JT65. I appreciate it very much.
This will be a little bit long story...
The summer extreme-multihop Es season is coming soon. This summer 2018,
so many people will use FT8. But with WSJT-X, there is an only one
frequency 50.313MHz. We can easily imagine that situation that QRM from domestic QSO or short range international QSO with neighboring country.
If a domestic QSO/short range international QSO and intercontinental QSO frequency are set separately, we can avoid such a useless QRM.
In order to prevent such a situation, I asked K1JT Joe an author of WSJT-X whether a frequency can be incorporated into WSJT-X for intercontinental communication.
The mail I sent to him is as follows.
-------------------------------------------------
Hello Joe-san. I am a Japanese Ham Radio Operator, JP1LRT Yoshiharu Tsukuura.
I am a user of WSJT-X. First of all I would like to thank you.
WSJT-X is a very cool and amazing software. I enjoy digital communication every day.
And I am a 6m band CRAZY. Last Summer, I did make a SUPER DX QSO on 6m band with JT65. So many people saw an incredible QSO. It was not a short-range communication with a neighbor country but a super-long distance communication across the continent.
With SSB or CW, we do not have many opportunities. But with JT65, we could make a QSO even a few, very weak openings.
Extreme multi-hop ES with JT65 , it was an amazing world.
However, there were two problems.
1.TX/RX sequence
When the strong station transmits in the receiving sequence, weak radio waves arriving across the continent have been covered and not decodable.
So we, Japanese people did try an attempt to unify the transmission sequence to the odd number side. Many Japanese agreed with the attempt, so we were able to get a quiet receiving environment.
2.QRM from domestic QSO or short range international QSO with neighboring country
This is a BIG PROBLEM. These signals are very strong. The station that cannot receive a DX signal start DOMESTIC QSO on the same DF of SUPER DX station.... We witnessed such a tragic scene many times last summer.
So we tried to separate frequencies between domestic communication and international communication. But we did not have much time to announce it, and the season of the extreme multi-hop Es has ended.
The 6m band in summer is very special. It differs from any frequency in the HF band.
So I have a suggestion.
I'd like you to establish a frequency for intercontinental communication of the 6m band at the official frequency of WSJT-X.
Currently 50.276MHz is set for JT65 and 50.313MHz is set for FT8.
Designate them as frequencies for short-distance communication with domestic and neighboring countries, and newly establish frequencies for long-distance intercontinental communication.
For example, for long-distance intercontinental communication with JT65 is 50.273MHz , with FT8 is 50.316MHz. This is only an example.
QRM from a domestic or short range international QSO, this problem happens both in Europe and the United States.
If WSJT-X does a new frequency setting for 6m band DX, this problem can be solved. Also, most of all 6 meters of digital communication enthusiasts will support this policy.
How do you think? Please contact your development team and your friends' 6m band lovers.
There are three months until the beginning of the extreme multi-hop Es season. We have enough time to announce it. Please consider about it.
I hope to see you on the air Joe-san.
Thank you for reading.
Best regards
JP1LRT Yoshiharu Tsukuura

And the answer from him is as follows.

Hi Yoshiharu-san,
Conventional working frequencies for the various JT modes are determined by users.
When there is good consensus that certain frequencies are desirable we include them in WSJT-X as defaults. Decisions about new working frequencies must be made by the world-wide user community.

------------------------------------------------------
So..... I would like to try to make a "CONSENSUS" in the world-wide user community.
I did try to contact with SMIRK, UKSMG, SixItalia, FaceBook Community - 50 MHz - The Magic Band - DX.
IK0FTA Sergio-san (SixItalia) and OE4VIE Jo-san (FaceBook Community -50MHz- The Magic Band-DX) gave me a responses.
They agree with my suggestion. I am still waiting some responses from SMIRK and UKSMG.
And this "movement" started to move little by little.
OE4VIE Jo made icons and started distributing.

If you can agree with this, please let your friends know.
I think that we will announce the operating frequency to ON4KST chat, but this 50.323 MHz will be one choice.
It would be nice if people who would like to enjoy domestic communication and nearby international communications or those who would like to enjoy long distance communication between continents should respect each other and create an environment free of conflict.
Thank you for reading my poor English.
FB DX. 73.
Best Regards
