Hello Group,

So along this same subject, is there any (reasonable) way to use one of these for a 10 MHz frequency standard for test equipment?

Re: Stratum One NTP server using a RPi

Dave Cole <dave@...>
 

I suspect he was thinking of the old days where GPS was not involved, but the Internet was used. Here is a current definition of a Stratum-1 device:

A primary server that receives a time signal from a stratum 0 device either through the GPS network or national time and frequency transmission is known as a Stratum-1 device.

As per NIST a GPSDO is a Stratum-1 device, so the GPS locked clock would probably fall under the general class of a Stratum-1 device.

In the old days people were asked to not connect via the Internet to Stratum-1 devices to reduce load.

Re: Stratum One NTP server using a RPi

not the least bit over kill. I use a rpi to keep time for all the computers on my network including the computer I use for wsjt-x modes. I use a Utart 3v/5v gps module, with a pps out. The setting up the server wasn't to bad, including compiling the NTPD with the pps support. FYI  I still looked up and used local reference clock at my university and for my geographical region to further reference. No problems in 5 years!!!!

Yes, I have been running one for a couple of months. 

I used the Adafruit Ultimate GPS Hat.

Re: Pi-gate not working with the 7" tuch screan

Tony D'Angelo <tony_d_33931@...>
 

It’s working now,

If I removed the ground pin (Pi 6) it works just fine with no ground so it must be picking a ground up some place I moved the jumper to pi pin 14 (also a ground pin) and it works fine.

I tried this on two pi 3’s one just out of the box so I think the pi’s ok at any rate she works.

Thanks all

 


Re: Pi-gate not working with the 7" tuch screan

Steve McGrane <temporarilyoffline@...>
 

Just chiming in here as the proud owner of a 7" touch screen.  They don't require anything special if its the official RPi model... plug it into the screen connector with the ribbon cable and boot.  Nothing else is needed.

The only complaint I have is that brightness control hasn't been implemented and I know this because the screen is too bright...
