## Step size
The step size when changing frequency can be changed as a secondary function when the frequency is selected. The range of settings are: 10M,1M,500k,100k,50k,25k,12k5, 10k, 9k, 6k3,5k,3k,1k, and 100Hz.

## Bandwidth
It is often the case that the PortaPack user does not know the filter bandwidth to use or what they have selected. The system uses: Finite Impulse Response (FIR) Filters and the settings are held in the dsp_fir_tap_hpp file, and are selected from the use interface. They can be selected for different modulation modes.
