As a very active CW operator, I view this as a VERY BAD move. The
presence of FT4 in that region is a most unwelcome intrusion. I view it
as the only major bad judgement call by the WSJT team.

Hi,
ARRL Letter on 09/23/2021 titled “IARU Regio 3 Considers Significant
Expansion of HF Digital Segments” triggered the dialog among JA WSJT
users about the recent activities of IARU bandplan proposal. It is the
great movement establishing “time-synchronized transmission mode
capacity demands” and we must encourage globally harmonized bandplan
implementation as soon as possible. However, I noticed a concern on 40m
proposal by the reason that I have experienced a lots of QRM from
lengthy, high powered and wide band occupied adjacent SSB operation on
40m at QRG 7074 FT-8 activity and it is not the best allocation for all
narrow band data users as FT-8 is the most favorite and popular format
today. From this aspect, I prefer FT-8 to take the most protected
segment from SSB operation swapping the allocation of Time Sync Data to
7040~7055kHz, for example 7040kHz. This principle to allocate lower side
to “Time Synch Data” is proposed on 80m. I understand the allocation
rule to prioritize the current allocation explained in the letter saying
“ a global narrowband conversational modes (e.g., PSK) segment between
7040 and 7044 kHz in alignment with existing Region 1 arrangements” but
that is not future looking and does not convince for me.
Thus, I wish to hear from the audience of this forum whether it is
painful enough for us to move WSJT i.e. FT-8 segment to 7040~7055kHz
and I must refrain from proposing to IARU R3 at this moment.
Any comments (from Region 1 especially) ?
Regards,
