Don, Since the ATU is still part of the 2.0 Beta, yes, it should technically go into the FlexEdge.
First, go to the ATU menu by clicking the "ATU" button at the top of PowerSDR. What do you have the "SWR Target" and "SWR Successful" fields set to? If you want the absolute best attempt to lower the SWR, set "SWR Target" to 1.1. You may also set the "SWR Successful" lower if you'd like. The the final SWR is less than "SWR Successful", that result will be saved in memory. Also, if you are tuning at nearby frequencies like you are doing, the ATU will attempt to tune faster based on what it found at surrounding frequencies, and will save the settings immediately if the SWR is less than "SWR Successful". If you would like to avoid this, you can check the "Force Retune" checkbox, which will strictly tell the ATU to try to meet the SWR Target. I would set the "SWR Target" to 1.1 and check the "Force Retune" button to see if the ATU can actually achieve a better SWR than when in bypass. Because the ATU was designed to support 160m all the way to 6m, the performance at 6m is not as impressive due the granularity of the L/C values. This is more evident especially at very lower SWR values.
