I have not only one, but two amplifiers that start at 10 kHz: an AR 25A100
(25 watts) and an AR 150A100A (150 watts). I only need 15 Vrms (4.5 watts)
into a 50 ohm load from the 50 source impedance of the amplifier, so what
is the problem?
Well, the standard also requires the that source

1% does sound extreme to me, but I am not familiar with the intent of this
requirement.
This does remind me about my experience years ago during an audit to the
automotive tri-plate immunity test. We had to run an artifact that was supplied

Hello,
Please note that not all of these wireless chargers would be Part 15
(47CFR15, as stated). Some might be Part 18, depending on the operation.
I think you'd need to look at the operation of the charger and see if any
form of 'handshaking' is taking place; even if it's just a recognition
This makes me realise how boring my reply was.
I'm sorry.
I'll try harder next time.

No, it's 99.99% pure gallium. Otherwise it wouldn't melt when you put it
on.

Oh I forgot:
“single fault” refers to a safety test where the test agency voluntarily removes
ground from an EUT to verify that the EUT still complies with the safety
requirements.
(but with only 1 safety layer remaining)

I don't follow the SWR thing at all, since I wouldn't expect it to be an
issue at such small fractions of a wavelength. (but I'm no transmission
line expert)
