All rigs are "noisy" if you run the RF gain full bore.

Experiment with backing off the RF gain and increasing the AF gain (if 
needed) until a good signal-to-noise ratio is attained by your ears.  
This applies to both CW and SSB.

It will also be helpful if you put the AGC in "fast" mode.

Finally, ignore the S-meter.  It will only confuse you and is needed 
only when comparing two or more incoming signals.  It has nothing to do 
with optimizing reception.
