Has anybody investigated the HF noise problems from the generic chinese 1-2Kw generators?
I have a GMC 850W and a Dingo 900W 2-Stroke. Both have the same alternator.
Looking at the waveform (after a 240 to 24V transformer) it's horrible with obvious
PWM of the field excitation an maybe 1000Hz.
Ignition noise (spikes at a regular 25 or 50Hz) most noise blankers are designed for.
Anybody looked?
