RF Systems has been talked down for years on this newsgroup (for some
people it's pricing, for others its product design), but I've been
very happy with the three items that I've used from them, and the MTA
is one of them. I have no hesitation spending the money for one of
their radio products.
They once threatened to sue me for making matching transformers.
No ****?

On what grounds?
They indicated in their letter (sure wish I still had it, as I'd frame it!) that it was
a proprietary design and I had no business making them and selling them.

I believe I wrote back asking them what was proprietary about winding some wire on a
ferrite toroid. Additionally, my case design was different from theirs as well.

I would think, unless they were prepared to produce a document signed
by Faraday, they'd have been thought twice about making THAT claim.

I never heard back from them again.

My design was based upon the work of John Bryant and Nick Hall-Patch and appeared in
Fine Tuning's 'Proceedings' in the late 80's as I recall.
As I recall, yours was somewhat different in performance, as well.

Here is the review which was published in 1992:

That's it. Thanks.
