This snapshots shows 10 FHSS channels used by 3DR 433 mhz link.

If we turn on Orange OpenLRS Radio Link, the spectrum is flooded, both sides, but at right a bit stronger, you can see 4 channels, so far I know should be 5.

Scroll up to higher freq. There you can see 4 strong channels from OpenLRS

image

then scroll down to lower freq.  and you can see up to 3 weaker channel signals from OpenLRS

image

Then going up to 436 Mhz, OpenLRS off, only 3DR modem up and running, WTF are those signals?

This snapshot is far away, almost 4 mhz up from 3DR higher channel. I cant explain this.
