Have you been watching when it actually first starts up?
- I would guess there is some drifting occurring before the frequency
stabilizes.
- But, the most important thing to know at this point is where it is
located.
- The WD8DSB portable flag + DXE preamp/attenuator + SDR is an awesome set
of RFI tools!
- You’ve got this.
- My guess: grow lights.
