Re: Ultimate3S third party GPS module with no 1PPS #gps


Hi Bela,
I would say the 1PPS input is MORE important than the GPS because it sets the U3 reference frequency accurately and keeps it on frequency as the U3 drifts with temperature etc, something you will need to do manually if you want to use narrow band modes such as WSPR.

The GPS is almost not needed as you can manually set the time and maidenhead locator.

Looks like you need to buy a new uP.
