It seems, most of the time, that I do have a problem with my GPS and the Pi4 when transmitting, Maybe some RFI or something. It seems however that everyone is experiencing a different problem depending on the rig, installation etc.
I know that the NTP is not always working perfectly as I have an (setup an) NTP server on my network and that My pi should listen to it and automatically update the Date and Time, especially if the network grid is down, for digital comms it is. But the NTP software/deamon on the Pi4 is funny to get running, maybe Im to stupid or to non-english to understand it.
As long as mi Pi updates the date and time at least once a day or while rebooting Im happy, but when is not very evident for me, it seems however you have to look at what your date and time is to see if it is working or not. The NTP software listening to the port do not always show if it is in sync or not. Maybe becayse the updates is not when you query the Pi. I just do not know this, But the solution maybe to disconnect the Pi from the internet and thus only listen to your NTP server and see what the Date and Time is doing. Updating or not, It may be the only way to be perfectly be certain if the Pi is updating the D&T from the local server or not. Also remove your RTC to make sure that this comms is working. But disconnecting the Pi from the internet may prove to be more difficult than what it would seems.
Anyway, all my PC's and Pi is updating from my local network NTP server at although not evident from querying the source, it seems to work and updating. I think this may be the only way to ensure that it is working.
