KX3 and FT8 DX Pedition Mode

[jh3sif]

Watching V6J on 17m FT8 DX pedition mode, I found that signal db of Fox’s lowest frequency below 300Hz is very low compared with its second frequency above 300Hz. Here are the example;

070830 -18 0.5 293 ~ JA2VXZ RR73; JA1UXC <V6J> +03
070830 -3 0.5 353 ~ JH3IMR RR73; JR1WYW <V6J> +07

This does not happen with K3. It seems that KX3 filters out below 300Hz.
