Kayaker72 -- I've noticed that Lightroom default Sharpening settings can increase the apparent noise in images. I tend to hold down the ALT key (in Windows) and move the Masking slider in the Sharpening panel until only the details I want sharpened show up in the white outlines. Then Lightroom doesn't sharpen the background noise, but only the subject details. This helps to reduce the effect of LR sharpening the noise in the background, making it more apparent/severe.
