Ray, Jeffrey, et al.,
The clock chip supplied with the kit is a DS1307. The DS1307 drift rate
of a minute per month works out to 2 seconds per day. That level of
error is easily observed toward the end of a 24 hour refresh period from
the WWVB chip.
The daily drift of a DS3231SN chip with
Hi
Which receiver are you using? Is it the ES100 IC from Universal Solder or is it
something else?
At least here, the BPSK clocks all did fine on the DST change over.
On power up, they seem to sync in less than a couple minutes, regardless
of the time of day.
All of that would suggest that

I don't know if this has anything to do with what you are experiencing, but
WWVB is currently undergoing an

My guess is: 11/07 is first Sunday in November - End of DST = NDST.

It is the ES100 IC plus arduino full kit from Universal Solder. The arduino
was pre-programmed.
Ben Hall replied that this is the result of the supplied program. The fact is
that the disciplined xtal controlled clock on the board is getting updated once
per day, every day. Since the LCD
Jeffrey,
Your questions are answered by notes in the source code.
The clock syncs once per day by design. That time is set at 00:00 UTC in
the software developers time zone in Eastern Canada. It works out to 8
PM in California. You can recompile the code to change the sync time.

I have been using the new BPSK receiver for NIST. There are two strange

It only syncs one and only one time per day, usually around 8pm. It also
shows an interrupt count anywhere between 2 and 50 every day. I am sure
it can receive the signal more
