Hi Paul, Good news!
I'm curious if the offset of 71000 Hz also works for Rich. If so, we simply add (the minus 71000) to all frequencies in our US list and we are done! Luc PS. The best way is to sort out why we need to use these trial-and-error-frequencies and not the common known and used frequencies of other projects. So far I didn't hear from the original author and I'm still trying to understand the ins and outs of the demodulate process. I wish I could find a useful article about FHSS and FSK decoding of Davis weather equipment signals...
