[Elecraft] FT8

[Rick WA6NHC]

If one presumes that everyone keeps their audio levels set correctly so 
they're not splattering or wide (not always the case, but presume for a 
moment), I've had better success with digital modes by turning the AGC 
OFF, so a strong signal doesn't cause a damping reaction (it won't swamp 
the other stations).   This has worked when another station near me 
(QRP) shared the band on FT8, which would have blocked anyone else 
(worst case).

If you monitor (listen) to the band on digital, turn your speakers down 
FIRST!  ;-)

Also never use noise reduction or blanking in digital, it causes 
distortion and may often produce ghosts in the audio (you decode them on 
multiple audio frequencies).

For terrestrial worm, the path loss is generally much lower and especially when there are othdf local hams or good propagation the signal levels can be high.   This often leads to excessively wide signals on different audio frequencies.
