Jeff Thomas GPSII Clock

[Mort]

I've owned the gpsii clock for a number of years and built it from the kit.

Lately, I've noticed that the GPS lock light never comes on.  I thought that the GPS board and/or the antenna had failed after so many years.  I got pretty worried as this is my most favorite Nixie clock.  Some years ago, Jeff sent me a new antenna.  I installed it to no avail.  I was using a PVC pole mounted on the side of the house right outside the basement where the clock is located.  I took the antenna down and laid it on the patio contemplating what to do next.  After a while I glanced at the clock and it was receiving GPS signals and displaying correctly once again.  It appears that the wired PTZ camera I had mounted on top of the pole must be interfering with the antenna.  It's time for a new mounting arrangement.

I have a couple of later small GPS modules that work well in my basement workshop and they don't require an external antenna.  Has anyone retrofitted a newer receiver to this clock?  I'm afraid the ability to do this is not in my wheel house.

Is there anyone currently making completed or kit Nixie clocks with built-in GPS?

Thanks,
Mort

Well, it's wireless GPS to the clock.

I thought about adding GPS to my most-recent clock, but the DS3231 chip I'm using is so doggone accurate I dont see the need. When daylight-savings started last month, I manually sync'd my clock to the time on my cellphone. A month later, it's still within a fraction of a second.

I also thought GPS might be a solution to changing my clock when daylight-savings started and ended, but after doing some research I found that those dates where time-changes occur are now standardized for the next 20+ years, so I'll just program them in on my next code update.

Greg, I used this:

No tables necessary, it does the calculations. If I had to figure this out myself, I'd be in a rubber room now.
