Paul, The best you can do for testing is to start the program solely for the wind transmitter and let it hop along all frequencies. If one ore more frequencies are found, you can look at the frequency error and try to correct this temporary with -fc (use the average FreqError and use the same sign. Example: average FreqError = -2000 => set -fc -2000) $GOPATH/bin/rtldavis -tr 2 -tf US, -maxmissed 51 -u -fc 0 The -u flag is optional. It reports the packets of other transmitters (only with ID=0 in your case) when they send on the same time on the same hop channel as for transmitter with ID=1. Success! Luc
