I agree. We are using PSK250 as the default speed, which can be easily decoded
with a 300 Hz filter. After the DX station handles its traffic with e.g. PSK63
the server will
automatically switch back to the default speed (PSKmail APRS, PSK250).
As most people will use a filter that is not less wide than 300 Hz there will
not
be a problem with being in anyone elses yard... The server will go back to the
'PSKmail watering hole' to relay beacons to APRS.
