Re: [Discuss-gnuradio] Raw Samples from Receiver

Noted... but in my defence the questions were asked to aid my
understanding of what is happening in the (stock) UHD code... the
background was to explain why I was bothering.

So, a friendly note that if you're running non-standard firmware/FPGA,
you should note that earlier, rather than later,
when you're asking for help from this list. 99% of the folks on
this list use the as-shipped FPGA/Firmware that
is compatible directly with gr-uhd/Gnu Radio.

So when a question is asked the "context" that most answerers have is
the as-shipped FPGA/Firmware. Which is why I delivered
my "lecture" about ADC samples getting mangled by the decimators in
the FPGA, and why would you care, etc, etc.
