The E signal appears to have a quite high noise of higher frequencies.
If you can find the source of this noise and remove it, it would be better but that may be hard to achieve.

Found it. Around 30+kHz was coming from the Motorola 1 Amp power supply I was using.
Need to find a suitable replacement.

What do others think of using a more basic Linear supply.
IE older transformer type plug pack with something like a 7805 instead of a switch mode charger.
