Jazzsinger, here is a link to an old thread where I was testing my new Gain Master that I had just received in November 2010. You'll see again that my reports using SSB are more conservative as to results, but I saw about the same as Penn and Oggy saw in the video that Penn made.
You don't think much about the A99, so I ask you...do you also think we can setup our A99's in some special high performance way, hooked up on a switch box, and make it perform this close to a Gain Master, another reported very effective working 5/8 wave antenna?
Plus, these guys, your neighbors, are testing using FM, and like you guys claim is the only way to test and be accurate. I can't argue that comparing signals in FM mode is more revealing than my using SSB, but my results tend to show about the same as Penn in spite of the concerns you and others have raised...about my failure with results when testing using SSB.

This doesn't prove that what you see is wrong, it just shows how different locations can differ in results, and I try to show how I get my results, and in this case we have to consider that someone was able to duplicate what I see separated by thousands of miles.
