Thanks for your investigation of the 918 file, Chuck and Theo. <<< It was a difficult file to study. The level was way too high: Audacity tells me it had to be lowered by 7 dB just to prevent clipping. After adjusting the level I then had to adjist the equalization as it was very muffled/ >>>
Both the 1 kHz DSP filtering of the C.Crane Skywave Ultralight model and the very high-Q tuning system of the FSL antenna tend to clip off the higher frequencies in received DX station audio. The extent to which this side effect occurs depends somewhat on the gain provided by the FSL antenna, with the larger models clipping off more of the high frequency audio. Although improvements have been made in recent Ultralight DSP chips, it is still unrealistic to expect the Ultralight + FSL combination to have the audio fidelity of a $1000 Perseus-SDR + broadband antenna, unless the Ultralight's DSP filtering is set at a level too wide for serious transoceanic DXing.
