Not sure what version you updated from.  I haven't seen that little dot on 
mine (2.044) but recently updated to 3.029.  Dot sounds like a nice idea 
because with the display freezing it is hard to tell where you have tuned 
to.  Have to pause and let everything catch up to see if you have over 

I am struggling a bit with getting a lot of benefit out of the SAF.  I'm 
sure it's just a matter of settings.  Have really needed it on the recent 
DXpedition from Spratley.  CW sigs in the noise.
