[hpsdr] ADC Question

Ah,

You're referring to RBW (Resolution BandWidth). I'll post a screenshot in a few weeks - it's always important to have a nigh high-res zoom / tuning window.

You are standing at the end of a road before a small brick building. Around you is a forest.
A small stream flows out of the building and down a gully. The sunspot count is 285.

 I've tried many of the software packages currently available for SDR, one thing I have noticed as the sampling is increased the filtering flattens out reducing the ability to notch out a close in signal which I like to do when operating. In some other testing I have noticed audio quality seems to suffer when you try undersampling large sampling rates perhaps it was done incorrectly I'm not a hardware/software engineer.
Audo quality is one of the key areas for me and the best audio and audio fltering I have heard using HPSDR was when I was running GHPSDR3-Alex wirelessly on a Windows laptop, I was not able to get the transmit function working so I moved on.
