I've noted the FT8 modulation Worm Drops knocks out my copy of PSK31 and RTTY when its only 500hz away. I see it happen when FT8 spreads down into the PSK31 band I work on 20 meters. Olivia can still get thru, but not PSK31 , RTTY, MFSK or Contestia. Sort of like how PACTOR grubs [the sound they make] wipe out those other modes in the waterfall close by. And this is using width and shift even to narrow my copy bandwidth of the Contestia signal for example. I am embracing FSQCall, evangelized it to the local and regional ham friends of mine, and like it. However, I really feel [IMHO] 14.080 needs to change as the default to something else. Folks this morning didn't move their VFO or pointers in the water fall when the RTTY signals where running in 1900-2500 today.
