I laid out a through-hole version of Warren's board in Eagle and had OSHPARK
fab up three of them. I sent one to Warren and am using the other two. The
one mod I made was to use a single darlington TO-220 instead of the two
transistor stage that Warren used. They seem to work quite well.

Always the interesting tid bits.
Thats the same double oven in the HP Z3801
I have one that went nuts. What a gooey mess. I set the whole thing on the

Hi all, I found a ML 200 loran C receiver and would like to put it on work.
Can anybody supply me with a manual?
Any help is very appreciated

I have been looking into WWVB receivers.
I see that the sources I had purchased from a few years ago are no
longer available(in the US).
I see that the format of the WWVB signal has changed a little as well.
Has NIST done something to not allow chip manufactures to make new
chips/modules ?

Hi
Quick summary:
WWVB changed the format of their transmissions. They now have a phase
modulation
component in the signal. That *eventually* will let people make a better chip
to demodulate
the time info string (and to get more info out of it). So far the new chips
have not been spotted
