Rain data. I am running the RTL-SDR program Luc set up on a Raspberry Pi 3 B with the Nooelec NESDR Smart v4 Bundle SDR. I am comparing it to a Raspberry Pi 3 B using a RFM-69 receiver.
Everything was working nicely until yesterday which was a sunny rainless day. The SDR setup reported 3.84" of rain with the current conditions graph showing two periods of approximately 1.3" - There was no rain, the RFM-69 setup showed no rain (so the data didn't come from the Davis ISS) so I was wondering if anyone has run across something like this and if there is a fix?
