Hi Christian,

I will start with the end as it will put the other explanations in context:

A. I would use a mode that does not care too much about frequency
accuracy and does not use automatic frequency control like THOR22 or
even THOR11. Since both these modes can be used by the European and
North-American servers and they are very robust I think this is your
best bet.

B. Regarding the PSK waterfall mark jumping to the noise I would
reduce the search band for that mode quite a lot, like to 10Hz. If you
don't use narrow version like PSK125/125R or PSK63 then you have quite
a few hertz of mis-alignment to play with even without moving from the
centre frequency. So try in Fldigi: configure/Misc/pskmail to adjust
the search range and AFC range to 10Hz.

C. For the connection to servers (from anywhere) I would go with a
common mode list like PSK250, PSK250R, MFSK32, THOR22, THOR11 for

I think that should maximize your chances.

I agree with your conclusion that there must be a network issue but I
can't help you there. Sorry.

All the best and enjoy the food and music in Martinique, "Bon sejour
et Bon voyage"
