I had discounted it because of the lack of info and totally unclear how

OK my 2 cents and others will have better comments.
You can use a far larger inductor in the efc line to try to reduce the

EFCs tend to be integrated by some cap. So they are slow moving compared to
the noise.
Better design is separate analog and digital supplies.

Hi
If you want to go a bit crazy, there are places that will package up die
for you. Depending on the resulting package, cost is in the $0.30 to $20
per part range. Most of the places

Hence the d-psk-r/costas loop soluyion released a year ago. But its semi
digital and analog and I have to say I never really figured out what the
magical VCO filter needed to be. Though I experimented. It works. But its a
guess.

Hartmut that is indeed a friend that can keep a persons knowledge going and
had been entrusted with the details.
Good luck to you and thank you.

Dear group,
please let me express my thanks
over a year ago.
My next stab is more of a digital approach using the STM discovery board.
Have to say I seem to get lost in some of the basics of getting all of the
crazy registers set.
However its value is it can run very very fast. So you can do some nice
sampling.

On Sat
really motivated me was several thread with another time nut and I
decided, why wait build a separate box and be done.
Also will send a separate email discussing the small atomic clocks and how
to use them for the remodulator.

Hello to the group. Been a while.
Wanted to update the group on the WWVB remodulator that allows receivers
like the spectracom 8170, Netclock 2
for free.
There has to have been a reason that all the clever none work receivers
went to the trouble of PLLs and such. They were pretty smart engineers.

Scientific American magazine today is a mere shadow of its former self,

There is no longer an Amateur Scientist article in each issue

interface is also the easiest to convert to a more 'robust' physical
media for electrically 'unpleasant' environments and DB9/25 connectors are
a LOT more reliable than USB connectors too!

I'll look into both SCPI and TSIP, and therein lies the reason for my

You almost certainly want to use SCPI which is managed by

I did this successfully a few years ago using an AVR 90S8535 to generate
IRIG B so that I could use a vintage nixie IRIG display with a Trimble

I have been watching the blitzortung system in the US for a few days now
and really like the clean and simple display. Very nicely done.
Also downloaded the information package.
Oddly it does not use any 12AU7s in the design.

Oh man does this bring back memories of 12au7s and loop antennas pre
internet 1970 as I recall. A QST magazine article. I built it and it used a
crt for readout.
There wasn't really a way back then to share the data.
But will say this is quite a nice setup.
