Gordon,
?
I believe that this radio can produce "splatter" if the level is set too high.? I have not looked into the code, so I do not know if any key shaping is done in CW mode, for example.? Overdriving the audio can also produce splatter.? The PA gain (NOT Mic gain) is post DSP filters, so splatter is still possible.?
?
Splatter is one reason the QRP-Labs QDX is not suitable for CW operation.? The QDX lacks key shaping, even though it is a single-frequency signal generated directly from the Si5351.
?
I could be wrong so that I will look for others' comments.
