least a month. I inserted a new battery and it did set. I did not watch it but

I thought the Junghans Mega clock used DCF-77 rather than WWVB?

There are a number of different models of Junghans Mega clocks, from desk
clocks to wristwatches. The ones sold for the USA market receive WWVB.

Joe,
All of the SkyScan clocks I know of have failed. I have two of them
that no longer work. However, I have two made by Junghan's that seem
to be fine. Take a look at www.junghansUSA.com

Thanks.

Burt search time nuts its all there. Its not a kit by any means.
Spectracom did a very good job. To good, though in reality they simply
reused the phase tracking rcvr from other units. Essentially the system
locks to the stable carrier creating a local replica and then removes the
carrier

Thats really a silly statement. The issue is this, we tech types put things
in rows and columns. But true artists use dead bug style with lots of wire
and parts flying
Paul,
Thanks for the information. Late last night I did a search and found
out about the d-pskr-r - an appropriate name, indeed. I gather
there is no final design that says, Here, build this and it'll
work. I have a malady that I suspect is common in this group; I hate
to throw anything away
Burt what you mention was indeed correct. But that non psk time was stopped
about a month ago.
Its pure PSK now as far as I know

I have four 15 year old Junghans Mega clocks through out the house. Ten

dead at least a month. I inserted a new battery and it did set. I did not
watch it but today I went with one of them through the house and all
Well, at 12:00 Noon I watched to see what would happen (I wonder if
the 12:00 Noon is pacific or elsewhere?) The problem continued. So
apparently the twice a day legacy time signal is, as Paul said, no more.
Checking around home we have several atomic clocks. Based on my
GPS clock time,
Sorry thats a bit much. It does look like a rats nest. Colors good.

Could be. If those are the am detector type clocks they will work.
The ones I have do.

Burt thats easy. The secret wwvb society of clock makers. I can assure you
the new silicon is $ XXK. But then perhaps some can afford that. There is a
company that does have the software and IP and its only one company they
have what ever the market is. Locked in. The funny thing is who ever they

My good old Spectracom 8170 is not setting time. I don't use it for
frequency, just as a clock for my Hazetorium. I live about 20
minutes north of downtown Los Angles in Glendale. The antenna I'm
using is the Ferrite Rod loop in PVC that came with the 8170. It's
located on my back porch
Burt
There is nothing wrong with your 8170. WWVB no longer allows it to work
correctly because of the phase modulation. They went to all psk about 1
month ago. They had been reverting back twice a day for things like the
8170.
So the ole 8170 is dead.
You need to build something like the d-psk-r
Burt
One other tidbit the phase mod will exactly cause what you see.
Spectracom used phase tracking to demodulate the AM time signal. Thats why
its nuts.

Paul,
U... What a revolting development this is. My 9150-52054 have a
smaller readout out that I can't see without climbing up on my bench,
so I suppose I will no longer know what time it is.
I've never really had to delve into the 8170 so I wasn't up to speed
on how they derived the
