[TenTec] Preselector, was: Re: Scads of used Icom IC-7300

[Katz Ajamas]

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.
