Hi,
Thank you very much for providing so many additional comments to my request.
However, these comments are not directly related to my proposal. I included the
fact that members are interested in JT65 phase out policy and it should be
decided by the owner of wsjt-x and then reflect to the working frequency table
accordingly.
I hope my request about FT8 TX frequency limitation will be included in the
next GA release.
Now, I close the discussion.
Finally, we are so happy guys to be able to talk this oversighted issue as a
happy problem.
Thank you.
Regards,
take

Please expand FT8 channel width from 2kHz to 2.5KHz, reduce JT65 channel width
from 2.0kHz to 1.5kHz and add the feature to limit FT8 TX frequency less than
2.5kHz at the next GA release. We also need to appeal to radio amateur society
and regulatory bodies to be able to expand total wsjt-x channel, i.e. total
5kHz considering popularity of wsjt-x formats and adaptation among major
DX-peditions.
Reasons are stated as follow.
1. The working frequency table was and is designed and planned that the width
of FT8 is 2kHz. However, the limitation feature of 2kHz to the operator has not
implemented to wsjt-x software.
2. Recently we observe above 2kHz communication practice by operators who does
not know above design concept and the interference to adjacent wsjt-x channel
such as JT65 is created.
3. Considering FT8 traffic expansion and JT65 traffic reduction trend, it is
appropriate for FT8 channel width to 2.5KHz and for JT65 channel width to
1.5kHz.
4. Such TX frequency limitation practice is implemented to JT65 operation at
30m to protect WSPR channel in wsjt-x software.
Note: Members are interested in JT65phase out policy and it should be decided
by the owner of wsjt-x and then reflect to the working frequency table
accordingly. Details can be seen in the thread of this topic in this mailing
list.
