My LORA node viewed on SDR

The entry-level Software Defined Radios are so cheap, I decided to buy one and play with it. Check out this max-hold capture of my weather station:

From experience I know the waterfall view is interesting. If the SF is sufficiently high you can see the chirps .

Cool. I will check that out.

Here it is:

Are these smaller signals likely to be from far away LORA nodes ? My Gateway does not register them.

You have too fast a data rate or not enough time resolution to see what’s interesting in a waterfall. In a situation where you can see detail, you’ll see the actual zig-zag “chirps” which encode the data.

I am not sure how to adjust the waterfall rate. The LORA signal comes and goes so fast.
