Subject: RE: [Discuss-gnuradio] Intel Atom is NICE.
There are many more ways than just lumping everything
I have changed the way the LMS automatic notch filter and noise reduction
filter is tamed. The taming of it was MUCH too aggressive (FIFTY TIMES) .
This effectively stopped if from reaching a good point. I noticed this as
we were working on other new things. I am anxious to get some feedback.
It would indeed be just that simple if the Wonder Radio were not an SDR-1000
knock off. You don't hear whining about the Elecraft k3 using PowerSDR to
get Panadapter support for example. The offense is not using PowerSDR but
other sins.

Which is why I do my measurements for that kind of sensitivity in the shield
room at my University of Maryland office or at our lab in Bowie, Md. In
addition, the phase noise leaving the 8640B, especially if you have the
reverse power protection is pretty ugly.

And WITHOUT a thud:
Eric Wachsmann, KE5DTO, has been succesffully moving the C# hardware control
out of PowerSDR for the Flex 5000 and has successfully done the first steps
of interop and is successfully sending and acting on commands using Erlang
to manage the remotable service and a gen_tcp
Is ctrl-Z already defined? This is a good idea.
