Hi all,) I know PRC guy has one of these Doppler units), and was wondering if there ever was or is he having now any trouble with receiving GPS data.

I’ve been able to open up HyperTerminal on my XP or Windows 10 machine and see the GPMRC Messages, they have the date and time but no lat and long. Could it be that the GPS receiver that they give you with the unit is suffering from the April 6, 2019 weeks rollover problem?

If so, can I just take a USB plug-in GPS receiver and put in mini din six pin PS2 style connector on it and will that work?

I did open up the unit, and noticed that there was an R1 resistor placeholder with no resistor in it and it seems to be by “following the traces” connected to the RS232 connector on the board.

Any advice help or suggestions would be greatly appreciated.
