You can find the frequency tables starting here: https://github.com/kobuki/VPTools/blob/master/DavisRFM69.h#L206
The conversion process is to concatenate the 3 octets - eg. for the first 3 it's producing the 0xE3DA7C hex number. You convert it to decimal and multiply by RF69_FSTEP, which is 61.03515625. Thus the first frequency is 911,413,818 Hz or 911.413818 Mhz.

These are the frequencies that work with RFM69. On Tue, Mar 19, 2019 at 12:41 PM Greg Troxel <[email protected]> wrote: > > [email protected] writes: > > > I don’t know.
