Hello,

I am working with the HRPT receivers files included in gr-noaa and I  
dont  
understand how them work because several blocks are created and use  
different parameters that are not explained so Id appreciate your help  
to  
understand them. Also, in case I understand them, if I want to check  
that  
the receiver is working, how can I do it? Are there any files available?

Thanks in advance,

Pablo.

Hi,

Open using GRC for example file usrp\_rx\_hrpt.grc and set default values  
and finally press the “Execute flow graph” tool button
