I agree with Jim on the use of waterfall for weak signals.  When I first got 
the P3 my main focus was on the top part of the display, the spectrum of 
signals and I ignored the water fall.  One day I discovered a signal in the 
waterfall that did not even show up on the top spectrum portion.  It was a new 
DXCC entity for me and he picked me up on my first call to him.  Now, it is the 
waterfall where I do my hunting most of the time looking for either QRP or just 
plain ordinary weak signals.

By the way, I only call CQ if there is nothing else I can find on the band -- I 
have gone for days without calling CQ.
