My last hearing test, I asked for and received a copy of my hearing
results.  I used to listen to CW at 650 Hz., and noticed that my speed
was slowing down as my hearing got worse over time.  

I noted a big dip in my hearing response at 600 Hz. from the results of
the hearing test.  I then changed the spot frequency from 650 to 540,
which is not nearly as depressed, I copy CW MUCH faster as a result of
that change.   

I in essence, have used the K3 EQ to adjust for my hearing deficiencies,
producing something much flatter between 300 to 3000 Hz. than I would be
hearing without the EQ.  

Over all this has really helped both my CW and SSB receive ability.  

73's, and thanks,
