I was not complete in my response, my apologies. The latest version of
MIL-STD-461E extends the frequency range of CS01 (actually now CS101) to 150
kHz. I ran a sweep with a 50 Ohm signal source and likely an oscilloscope
load. This was a very small low power transformer. I don't know if it

Why not at 240V? That way the ACA's requirement in Australia is satisfied and
the test voltage is
still within 230V tolerances.

Interference from an adjacent/inband radiating source is
likely to cause the receiver's AGC circuitry to limit the
incoming RF signal to the point where the signal you're
trying to receive gets buried in the system's noise. Or,
the interfering signal is of sufficient magnitude so as to
simply
I would expect a 50/60Hz transformer to be a very poor transformer at
150kHz. The leakage inductance alone would attenuate the signal
substantially. The iron laminate material in the core would also be very
lossy at that frequency.

Richard,
The circuit you describe would not be acceptable if your intention is to
have the LEDs touchable by a person. This is because you have not provided
adequate isolation between the source of hazardous voltage (230 Vac-rms
mains) and an accessible part. The only capacitor type that

he would most definitely want a CE as well as a an FCC mark stamped on
