Congratulations!

There isn't a lot of news.. The interest on the net quickly boiled down,
my sample works and so there was not a great incentive to follow that
with much energy. And getting boards out does not mean that those
are really built or that there is any feedback at all, as I saw with my
220pV/sqrtHz preamp.

The Altium Designer files are available, maybe the regulators should be
changed to sth. bigger (TO220 with small heat sink or so)

(who will spend this rainy&cold Easter weekend on a 1pps generator
whose outputs can be skewed in ps-steps to check the linearity of
T2D converters or time stretchers.)

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

Not having Altium, how can I convert this into a board?

I could use a few.

Now, that would also come in handy here. My pulse-generators have a
little too much jitter on them even if the resolution is useful.

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 john@pcsupportsolutions.com
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

It is possible to convert Altium files to Kicad

https://github.com/thesourcerer8/altium2kicad/

This might also work, but Altium seems to be a work in progress

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,

Hi, dave & the others,

I have changed the regulators to TO-220, it will still require attaching
to some isolated metal plate.
In the prototype I have 5W 5V6-Zeners to drop the input voltage, they
run quite hot (but are not
screwed to a heat sink as intended by their manufacturer.)

The outputs now have discharge resistors, the lowpass now can have
higher output impedance
at 5 MHz, making the 2nd 5 MHz trap more efficient. This is still untested.
The board is slightly bigger, still needs a little bit of cleaning up.
I still can accept tech. ideas for, say 3 days.

open:
enforcing symmetry, changing the output transformer of the doubler back
to 9:1 auto-transformer
for more harmonic suppression & cheap gain, so the output drivers

This is the phasenoise btw:

A .pdf & laser printer is what I have used also.

There are more requests now so we could do a small production run. I'd
like to avoid
having many versions of this.

regards, Gerhard.
