You give up too easily, Bob.

Here you will find schematic, bandpass curves, everything your little heart
desires! (hi)

The price is just under 600 GBP or about $800 (700 EUR).

That actually looks pretty good to me!

I am thinking about a home brew tracking preselector and started looking for
other examples. Then I start to read that the Flex guys appear to be needing
a preselector too! A bit of a surprise. Then I see there is one!

Alas, no schematics so no chance to pick their brains without buying one.
This I will not understand. If someone is going to copy your product, they
will not be deterred by lack of a schematic. They will just buy one and see
how it is built.For the purchaser who is comparing products or the home brew
guy... well, I am reluctant to purchase anything that is not well documents.
I am still a bit pissed off with Tentec for not releasing up to date Eagle
documents.
