Title: Are there too many harmonic signals?
Post by: macnickers on February 03, 2022, 11:12:06 AM

I have been using the RFM69HCW for about 5 years. Suddenly. I stopped getting data from one of the nodes. I recently bought an SDR and see waveform in the attached image.
My question is this the correct waveform for a 250bps signal centered on 910Mhz?

Thanks,
Mac

Ok so one stopped working, still getting data from the other nodes?
You are centered on 910mhz, and there seems to be a signal there.
Nothing else can really be said about that signal from an image.
