the 12AU7s again for the vlf pre-amp they were $1 or so 7 years ago. Now
It was QST and Max is right. I built it. There was a e-field antenna for
amplitude and the crossed antennas the XY access. I guess the old brain has
somethings correct.
Now can I remember the tube line up. Heavens no. :-) The CRT was a little
mil surplus 3p...
But enough of that. Whats the chance
QST lightning radar. But what a mess you get with google and every
lightning and radar TV station in the US.
Oh well if your replacing TVs every few years whats a few more opamps?
Now how does a poor man build something for what started this whole thread?
Time for me to hop off this thread.
John welcome to time nuts. This won't be a super long post have other
things to do.
Search for d-psk-r and you can see a few of my exploits. Summation. It
ain't easy.
It appears to be really easy unless you are far away like the east coast.

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 and Truetime DC60 to work with the new
BPSK signal and display accurate time.
The plan had been to leverage the accurate d-psk-r 60 Khz clock for the
everyone in a day
or so.
Google mails kind of a pain in that respect.
Regards
Paul.

Many of the old receivers use them spectracoms come to mind. They are big
units and +- 40 Hz BW and I am totally unaware that they can be found
today. That also goes for nice transformers and inductors to build higher Q
circuits.
I built a opamp chain and it worked well but those crazy amps do
most of the hardware was available.
Thanks for all the comments on this. At least I understand the problem
now, and why the solution will take some work.

Good luck to you and thank you.

Emailed Pete at Everset about the ES100 and 200 chips and unfortunately
only chip dies are available. I am good but not that good.
He suggests that someday a vendor will be selling a clock and thats the
only reasonable option that will be available.
All in all completely unattractive, as someone

they have to try them out somehow. The MPW run costs them $5K so they
don’t spend a lot on the packaging.

An interesting article much like one Bert sent me circa 1989 quite recently.
The key to these systems is that the transmitters have very good references.
In the US at least we have no requirement for that level of stability on
the MW broadcasts. Though evidently some stations are quite good. I
