Hi
Go indoors in the basement inside an inner room. You can at some times of day
get WWVB.
With a normal building, GPS isn’t going to make it. Even if it does, the
signals will be degraded
enough that you will have a tough time using in.

Interesting thought. I wonder if anyone has tested WWVB reception in a
deep underground location such as a sub sub level in a building or parking
garage?

Hi
If you are fairly deep inside a building, GPS isn’t going to get there. WWVB
likely
will make it to an internal location.
If you are convinced that WWVB is un-jamable and that GPS is easily jammed, WWVB
would be more robust.
That’s about it.

While reading this thread and pondering whether to buy and fool around with
an ES100-based module from Universal Solder, I suddenly found myself
wondering if there was any advantage to using the time received from WWVB
vs just using an inexpensive GPS receiver. The ES100 module costs about
$70,
Good detective work. Oren is who I used to talk with at everset.

This is good work and I have been following.
What caught my attention was the 2 X very fast codes. I remember talking to
the everset folks early on and the high speed code could be turned on. It
had not been. The ES100 will not track that code as mentioned. Did not
think they actually ever turned
The "Two High Gain Antennas" feature is laughable :-)

hello to the group.
I really am enjoying the stories and in reality history about a great
company that I am very proud to actually own a lot of its technology.
Though purchased for $/lbs at hamfests and such. All needing TLC and all of
it teaching me more then a few lessons on how to do things.

Hi Graham,
That's very nice work. And you have uncovered several unusual effects in the
ES100. Bugs? Features? If we time nuts keep up the good work to evaluate this
chip, we are likely at some point to get an informative response from the guys
who designed it. They read time-nuts.
So now

I don't believe that HDEV result. For many large runs of simulated normalized
