I've got big antennas and am surrounded by big signals when I work FT8, 
but I get by just fine.  Those strong signals are causing AGC in the rig 
to reduce RF gain. What we need to do is drive the computer audio system 
harder from the radio so that weaker signals are still within range of 
the A/D converter in the computer's sound card. The fundamental settings:

1) Full RX bandwidth, let WSJT-X separate the signsls
2) Reduce RF gain (or use ATTEN) to prevent overload
3) Set audio level feeding the computer so that, when those strong 
signals are present, the green bar on the left reads about 75-80 dB but 
doesn't turn red (which indicates digital clip).

Yes, I know that #3 is not what the instructions say. But I have a LOT 
of weak signal QSOs on 160M and 6M because set up that way.
