[Elecraft] WSJT KX3 and GPS

[James Lauridson]

I am new to the KX3 and am loving it.
I am planning to add WSJT.
I will not have an Internet connection for the laptop to get accurate timing.
I am thinking about a USB GPS unit attached to the laptop that would give an accurate time.

My questions are:

1. Is this a reasonable solution to this issue?
2. What GPS hardware would work for this?
3. Is there another way to get accurate time to a laptop without Internet connection?

Thanks,
Jim
