Hi KYU,
thanks for you suggestions. We strive to suggest working frequencies
which are globally coordinated, in IARU regions 1 and 2 the band plans
mandate CW only below 3570 kHz so it is not possible use frequencies
below that worldwide. We do have a capability in WSJT-X to set IARU
region specific working frequencies and for 80m we currently propose
3570 kHz as it is suitable for JA operators being within their licensed
allocation. Looking at the HL band plan it seems that 3523 kHz is better
than 3547 kHz because it is within the 3520 - 3525 kHz digital modes
section. I note that 3525 kHz is designated as an emergency
communications frequency, I assume this is LSB, will that cause issues
if we suggest 3523 kHz USB for FT4 operation?
