On April 6th the satellite GPS system is going to be reset, does anyone out
there know how this “reset” will effect the Trimble Thunderbolt that many of us
use to “discipline “ the frequency on our K3 and K3S radios? I’m told that
older sat programs will not work after the reset. My Trimble uni

As NW8L pointed out, there are simple updates to restore proper date displays
in GPS receivers.
An update should have a release date inside the build with the associated GPS
