Dave is spot on.
In a couple of cases I'm familiar with, China not only delivered goods
with quality equal to or better than US manufactured items but with
their technical capability and desire to excel, were able to offer
suggestions that improved the product AND lowered the manufacturing
cost. China is not the only example. A significant number of other
countries are just as capable as the US to produce high quality goods.
Just look at some of the amateur radio 'stuff' available on the market.
We aren't the only ducks in the pond anymore, and don't blame politics.

Well, if that's the case it means that Fair-Rite did a poor job of
transferring the manufacturing, and yes ... I've seen a bunch of other
companies do the same crappy job of it especially when all they were
looking for was quick cost reduction. Those companies who made a
commitment to do it right have found a large pool of highly
conscientious technical labor in China just like we did. Those who
merely tried to port their processes over to some existing facility
usually failed.
My gripe is that simply bashing anything made in China is decades out
of date and a bad generalization.

Sadly, there is much evidence. Fair-rite quality really took a hit
after they moved production to Asia. So much so that many companies
have had to institute new QA procedures on incoming product to see if
the characteristics come close to fitting the requirements. One of
the biggest ones is large 60Hz transformer toroids that were failing
in normal service because of the manufacturing issues. The company
does still have some non-Asia manufacturing capability, and many
companies are specifying product only from those sites.
So yes, the toroids do have issues that are very problematic.

I find that kind of China bashing pretty funny. Ridiculous as a
generalization.
I worked for a large semiconductor manufacturer for over thirty
years and we ended up putting a joint venture manufacturing
operation in China ... not simply for low cost, but also to be able
to serve the Asian market better and to be able to head off future
tariff concerns within China. We spec'd our own equipment, we
trained all the operators, and we put our own managers in key
positions. Most of those positions are now staffed by locals. The
resulting quality was literally best-in-class on a world basis. MANY
other U.S., European, and even Japanese companies have done exactly
the same, and nothing says that Fair-Rite hasn't as well.
It is certainly true that many of the smaller locally owned
companies in China have sloppy process and quality control, but
companies like the large subcontract outfits in China put equivalent
U.S. manufacturing to shame for overall manufacturing excellence.
In the case of ferrites, the problem is the inherent variability of
the process itself and the problem previously existed wherever the
ferrites were previously manufactured ... including here in the
U.S. Why you think the variability was less before the
manufacturing went to China is beyond me. Several of us here have
already explained that it wasn't.

<The posts from both N6RK and AB7E support my statement that
variability in ferrite parameters has been known for a very long

and that therefore Steve G3TXQ could not have known about it.

## I believe it was N3RR that bought 700, (seven
hundred) type 31 cores from one supplier, all from the
same lot number..2 years ago. He used a simple 1 turn link
to test them..and then graded them. They were all over the
map, + and – 22%. Thats a whopping 44% spread. No 2 ferrites
the same! ALL made in China......so what do you expect ?
So much for fairite moving their factory to China. QC
down the tubes ever since.
