    I managed to use my older USB/Bluetooth Delorme Earthmate BT-20 on the FT991 by channeling it through a raspberry pi. I noticed that when I did a cat command on the GPS's usb, it would output the raw NMEA data.
    So all I did was get a usb to serial adapter, plugged it between the rPi and the FT991, and piped the data from one usb to the other.
    I used the rPi for fldigi and digital stuff anyway, so it was just an extra cable.
    Worked like a charm. I was able to get location and time on the FT991 with a USB GPS.

    That is cool. A pipe | can do some cool stuff.

    Win10 | Recycle Bin is my favorite command for a Win7 machine.

    Have fun.

    Yah, I just wanted it to look a little more tidy. Apparently, you can cram the nema data over the USB as well.

    I assume the raspberry pi zero has enough beef to do this - pop it in a box with USB on one side, serial port on the other, nobody's the wiser. Pi Zero is about five bucks.
