After doing some research, the 1kw will not allow you to currently pick the frequency for CW or go into CW mode manually. That feature may come down the road with future software updates using a 1kw transducers.
If you are using the DI-FFAMP box with a 2/3kw transducer, you have the ability to pick CW mode and slew the frequency within the frequency range it is capable of.
