From design variables, I was expecting a somewhat lower value, around -110dBm/Hz, but between the NoiseCom noise source and the output there are several things (attenuator, filter, amplifier, directional coupler, variable attenuator, ...), so perhaps there are slight differences between estimated insertion gains and losses accumulate up to 5dB.

I have to wonder how scrapping all of our gas pumps, road signs, cooking utensils, and most of our manufacturing machines would save us a trillion dollars a year.

Some of the art is to compensate for various effects, so accurately model, estimate and compensate goes into the tricks of trade today. The standard shifts as better methods of realizing them occurs, the kg has been taking a long time to shift from the original lump of metal. Cheers, Magnus

Is it possible to estimate the opamp's phase noise at a specific frequency (say a sinusoid at 10MHz or 100MHz) from these curves? I'm assuming it can be seen as amplitude noise that is converted to phase noise. Which in turn make it seem to me that it is dependent on the slope of the zero-crossing.

The Oncore driver can load certain parameters (e.g. the fixed location, mode of operation, and -- I think -- the current estimated time) into the Oncore receiver's RAM, but doesn't do anything to the firmware on flash. Cheers!

It was a puny number of Barn Swallows compared to the huge numbers estimated along the lower Connecticut River, but it was still an interesting flight to watch. There were also at least 450 Common Grackles which went to roost for the night in the reed beds upriver from the bridge. Charlie Barnard Jr. Stratford
