PC time accuracy with no internet access.

[VK4WDM]

Hi Wayne,
If you are using a laptop, perhaps you could set the time where you have internet access then take it out to the shack. You should check the time accuracy every 10 minutes or so using WWV as you suggested.
I know for WSPR you need to be within 1 second. I use Dimension4 to keep the laptop on time.
Is there any way you could get the internet to the shack? Wireless router, prepaid dongle?
No doubt others will have better suggestions for you.

Hi Nev

Up till now I have used Dimension 4 and a prepaid dongle but current policy does not allow internet access of any sort. I had thought about the laptop but I would have to check whether "private" laptops are allowed in. This is a very difficult environment to run a ham station.

Hi,
I use a GPS Module ( Motorola Encore) which gives Serial data in Nema format combined with Tardis software to lock the PC time.

This frees me up from the internet time servers and their associated issues.

Even works with an elcheapo USB gps module.

Hi Jim

This sound's interesting but easy on the jargon, I am a computer-challenged geriatric Does this mean that I could set the clock using a hand-held GPS provided the shack computer has the Tardis software installed?
