calibration relative humidity #14

adapted sdrpp_radiosonde so it exports all measured values to the log file. Wrote a script that uploads the data to Sondehub as they come in real-time. Sondes used in this area are RS41-SGP. As more stations follow a sonde, one can compare sdrpp_radiosonde reported measurements, with those reported by other rx stations, using radiosonde_auto_rx. Perfect match, except for Relative Humidity. And for a few data missing in sdrpp_radiosonde. At high altitudes 20-30 km, radiosonde_auto_rx reports RH in the few percent. sdrpp_radiosonde does not report under 5%, and through the entire trajectory consistently higher than the other reporters. Of course either can be right, difficult to tell, but what causes the same base data to yield different results? Other questions: When radiosonde_auto_rx reports that the burstkill is inactive, sdrpp_radiosonde reports some burstkill integer, suggesting it is active. Which one is right? SDR++ general question: is there a way the radiosonde module can know what the tuned frequency is, and what the signal strength, so it can export that into the log? Now add the frequency via a rigctl query. But not elegant, nor can I get S/N that way.

Great work by the way; the decoder works really well. Thank you!
