I have noticed that the average signal levels seen on the Flex 5K S meter as compared to the panadapter seem to be quite different. For example, on 40 meters on a section of the band with no signals, the panadapter shows a very flat line centered at -110db which should correspond to and S meter reading of about S3. However, the S meter reads S6 with the meter set to either "signal" or "sig avg". That is an 18db difference which is quite large.

I checked with Dudley the other day and he indicated that the panadapter would never read as high a signal level as the S meter since the panadapter is limited by the display frame rate. He indicated that the S meter should read the correct value. I guess this translates into some difference in the sampling rate.....not sure. When I switch to my Icom, the S meter there seems to agree with the Flex panadapter much more closely. I would think the Flex should agree more closely as well. However, I don't have any first hand experience with any other panadapters. So I wondered if anyone had any thoughts/experience on this.
