On the wiki, it clearly says 'CENTER FREQUENCY'. 

I have written a FAQ page about radio tuning 
which explains why mentioning Dial frequencies does NOT work.
I really don't know what more I can do...

PSK125 does NOT work with AFC off!!! 

The effect you get is that very short frames (pings) come through and 
with longer frames the end of the frame is not decoded properly.

We have changed fldigi in such a way that AFC is limited to some 20 Hz either 
side of 
the sweet spot, which means that you must hit the server frequency quite 
It is ok if you change the frequency in 10 Hz steps, the AFC will cope with 
that, and not loose 
sync when you do it.
