Re: Waterfall width


 

There is a 40 MHz crystal filter with 25 KHz bandpass that puts a physical limit on the span.

You can¡¯t, because the crystal filter at 45 MHz and sampling rate using the inexpensive A/D will not allow a wider waterfall

Hi Mike:

I'm not sure what the rig uses for its ADC/DAC, but those play a limiting role in the meaningful range of the spectrum and waterfall displays. I'm no EE guy, but the hardware puts severe limits on what software can do to present information on the display.

Has there been any change with v3 to support a wider waterfall width (e.g. 100 kHz or wider)?
