Re: [CAD_CAM_EDM_DRO] Motor Noise?

Well Peter and Alan,
The power talk about is comes out of a 4 KW transfomer at 4500 Volt
and is pulsed at 1,3 or 1,5 MHz by a huge (12" tall) radiostation
amplifier tube.
I guess that the interference eradiated of the 40mA consuming miniPLC
is a minor issue. Don't you agree?
