 		Below that, the first graph shows a coloured spot for each callsign received, with the X and Y axis showing the number of times that

 		The second plot compares the SNR reports, <u>only for callsigns with decodes in both all files</u>. Again, points lying on the dashed diagonal line
 		represent equality between each file (receive configuration). The number of callsigns received
