Rich, I don’t know. What we do know by now is that the well known and proven to be good frequencies (of RFM69) are not working in program rtldavis. We can do one of two things to solve this. 1. Find out what the problem is and fix it. This is not easy and a thorough knowledge of the demodulator

Yes, you summed up correctly. All things point to the fact the Golang code is at fault somewhere. On Mon, Mar 18, 2019 at 1:05 PM Greg Troxel wrote: > nls writes: > > > As mentioned earlier, the frequencies were sniffed in original VP2 > consoles > > (you can find the posts about that in wxforu
