Hi Jordan,

The file_rx_hrpt needs baseband data as input. The output file is the demodulated frames file.
To view the final result you'll need a HRPT viewer.

The data from NOAA class is post processed (ready to be used)

Due to server failure I could have pointed you at our HRPT viewer and HRPT GR repository I'll get it up shortly... http://www.poes-weather.com/~patrik/1.7GHz/HRPT/Sept-9-2010/Screenshot-N19-4.png

Does anyone have any experience using the 'file_rx_hrpt' program in the gr-noaa package? I've been unsuccessful using it with raw HRPT data files that I downloaded from NOAA's website (www.class.ngdc.noaa.gov). The receiver does not seem to identify any frames.

I would eventually like to process data received by a USRP from the satellites, but was hoping to first familiarize myself with the general HRPT receiver flow by using raw data files. If someone could point me towards an HRPT data file that is verified to work with the receiver or advise me on how to get the receiver working with the NOAA files, I'd greatly appreciated it.
