Many times, with spectrum analyzer screen prints, etc. Some of those in the near-astounding category.
At this point can't refer you to them but you can find them with some searching. A 3 dB improvement in TX strength will not be noticed either, until it is used in a situation where you're close to or in the noise. Close neighbor hams with a sequence of installing the syns, and screen prints in the reduction in phase noise sidebands for each step, and noticeable improvement in interfering with one another. For me that was the killer demo. The "news" aspect of the syns is pretty well past, so don't see much about it any more. 73, Guy On Tue, Apr 25, 2017 at 4:33 PM, Wes Stewart <[email protected]> wrote: > I've seen these rave reviews about the new synthesizer many times.
