Count me in for one (maybe two, depending on cost of the board + parts).
I have been working on a design for an elliptical lowpass filter following a diode doubler and a small amount of amplification.. I have most of the parts, using a couple of RFExtra's developer boards (Ebay item 150203651783). Only need a couple SMD inductors and can start building it. Will be continuing with that in a week or two, when I get over a minor surgery. Will be interesting to compare to two approaches. If it turns out to be a problem to duplicate the board in volume, I'd really like to get an actual-size PDF of it for my own use.

Cheers,
Dave M

Hi Time-Nuts - FWIW, the is a 30 day free trial of Altium Designer at
http://www.altium.com/free-trial?gclid=CKnpkaux38QCFQotaQodoaYAWQ

The download requires a company name and email address.

I for one, would like at least one of each of Gerhard's boards.

Would anybody like to volunteer to create 10-20 boards and sell them?

If people are interested in boards, they can pm me at
[email protected]
And I will make a list and post it.

In your email, provide your name and email address and how many
multiplier boards and how many low noise 220pV/sqrtHz preamp boards?

I have no time to do any more than that.

Is this worth being a TAPR project?

Trying to help, John K1AE

Gerhard - I would like to make the board if you could make the layout
available.  I don't have Altium, so would need the artwork to be able
to toner transfer the board.  Is it available?

Thanks
