New test function in program rtldavis To all,
The rtldavis program has now an embedded frequency test function. With this function the frequencies can be detected used by Davis Vantage weather stations. Usage: $GOPATH/bin/rtldavis -tr 1 -tf US -startfreq 902000000 -endfreq 928000000 -stepfreq 40000 Warning: For the US, AU and NZ bands this test will take a long time! -stepfreq 10000: 4 days! -stepfreq 20000: 2 days! -stepfreq 40000: 24 h -stepfreq 80000: 12 h Below the output of the test for the EU frequency band ============================================================ My command was: $GOPATH/bin/rtldavis -tr 15 -startfreq 868000000 -endfreq 868600000 -stepfreq 2000 Note: I used -tr 15 because I have 4 transmitters, but you will get better results to do the test with just one sensor. $GOPATH/bin/rtldavis -tr 1 -startfreq 868000000 -endfreq 868600000 -stepfreq 2000 08:33:08.507848 TESTFREQ 1: Frequency 868000000: NOK 08:33:25.009595 TESTFREQ 2: Frequency 868002000: NOK ...
