What are the correct settings of RF Gain in 6600M?

In the manual for the 6400M/6600M it states that the RF Gain below 12M will generally be set to 0db for greatest dynamic range.   IN Sherwoods test results he states, "Test data for 6600M is after May 2018 PEN (Product Enhancement Notice). Due to the insertion loss of 7-pole bandpass filters on the contest bands, recommend +16 dB preamp during daytime on 80 -17 meters if in a quiet location. 15 - 6 meters may require +32dB preamp for an adequate noise floor".  How are users setting the RF Gain and what are your results?

Thanks  Bill--K5ZQ

    Well I don't live in a quiet location, but the default gain setting have worked well for me. I have tried adjusting the gain, but it didn't really help the S/N ratio.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
