[TowerTalk] Ferrites 31 vs. 77 material

[Rob Atkinson]

>My gripe is that simply bashing anything made in China is decades out of date and a bad generalization.

Gripe all you want but you've used a few examples to try to refute a
generalization that has basis in fact.   There are far too many cases
of poor products from outside US and Europe, not just China, that
disagree with your belief.

Chinese vacuum tube production is all over the place--some are great;
others flash over.  Consumer products missing RFI suppression
components, and then there's steel quality which has been known to be
life threatening when used in critical structural applications.  US
Gov't procurement has a whole course on how to spot knockoff hardware.
Would you go up a tower made in China with Chinese ceramic insulators?
 (This is Towertalk after all.)  On the other hand, smartphones from
off shore seem to have no issues.    Obviously, when manufacturers
enforce QC and micromanage the process, things go well.
Otherwise.....cheap ham handy talkies for $20 are the result.

I never knew anything about the QC variations in ferrite until K9YC
mentioned it.
