Anyone who has done this work more than a few years knows the liturgy;
it starts with cost, moves to expense and ends with failure.
I might be one of the EMC engineers you describe, because truly,
following very simple design principles costs little, done at the
outset, and averts much. But
I was once sent on a interference complaint a previous troubleshooter
had attempted to fix with ferrites. *Forty-two* of them. Taking them
off didn't change this more than 1 or 2 dB but a series termination
resistor in the clock line substantially cut emissions in the lab. The
real problem
You guys got me a job at Tandy a few years later. Thanks!

Management considers anything that has no direct impact on sales as a cost.

Hi Ghery,
I thought you were joking about the Wi-Fi Tee Shirt.
But it's real at the link you provided – except they're out of stock.
Every size, from S to XXL is out of stock – with no ETA on new inventory.
These would be great to wear when doing IEC61000-4-3 or RS103 testing.
Bummer!

No joke. Sorry they’re out of stock. They are funny. I’m not sure how
selective they are on frequency response. Guess I ought to bring it into work
and test it some time. ☺
