Noise abatement

[Jorgeminator]

Hi Steve. Looks like power supply noise on E-field. Exactly like my E-field before I switched the power supply. Check this:

Any clues where this could originate from? It's the same pattern on both the H-field C-channel and on the E-field. Power supply related? The noise is there even with the antennas unplugged.

This interference could come from the inverter working in the nearby (even up to 50m) - eg. on-line UPS, solar inverter, etc.

Nope, it was the power supply's fault, both my 1A HTC charger and LG 1.8A charger produced the noise seen above. I picked up the new Apple 12W A1401 power supply today, the noise is now almost completely gone. The fact that the noise was only present on the H-field C-channel and the E-field channel, even with the antennas unplugged, pointed towards a power supply issue.
