Hello everyone, I'm new to this list but also I'm new to all of this GPS timing world, all do used GPS before but as a regular GPS user. I bought on Amazon a couple of USB GPS: U-BLOX UB-6010 GlobalSat BU-353-S4 I also have registered version of NMEATime version 2.0.25 running on Windows 10 1909. NMEATime seems to work OK with the U-BLOX as I type 10 GPS in blue. But I tried the GlobalSat and cause issues with NMEATime that will Not Responding and had to End Task. I did unplugged the U-BLOX from the PC and put the GlobalSat instead. If I understand correctly the GlobalSat perhaps is a better GPS receiver than the U-BLOX but is giving that error, what could be the issue ? For sure I have more questions and more to learn about GPS Timing, etc. But for now I will ask for your help, thank you. Regards. Juan TG9AJR
