I'm researching digital signal processing (DSP) because my Yaesu FT-100 came equipped with DSP functions. However I have not exploited DSP to its fullest potential while contesting in addition to learning about DSP. And now is the time to advance my understanding.
Yaesu FT-100 DSP functions.
- DSP bandpass filter.
- DSP CW peaking filter.
- DSP noise reduction (NR).
- DSP notch filter.
- My DSP bandpass filter may enhance the FT-100's receiver selectivity by modifying the bandwidth of the receiver. I can manipulate DSP low-pass filter (LPF) thus allowing adjustment of the high-cut LPF. Then, adjust DSP high-pass filter (HPF) which modifies the low-cut HPF.
- DSP CW peaking filter is especially useful when the band is crowded ie. contest environment or for very-high frequency, ultra-high frequency weak signal operations. In effect, I'm changing the bandwidth of the DSP CW peaking filter.
- DSP NR maybe used to improve signal-to-noise ratio on weak signals. Hopefully, an operator on the receiving end, uses DSP NR during a contest?
- DSP notch filter assists in the removal of one or more disturbing carrier or heterodyne signals from the audio pass band.
In contrast, I'm experimenting with the FT-100's DSP band pass filter and DSP CW peaking filter through the weekend. What a difference this exercise is making in terms of learning about DSP and improved operating technique.
