I can only reaffirm my willingness to try any build provided.
I would suppose this is somehow related to the Garmin's weird NMEA
message timing with respect to the PPS output. I don't remember the
details, and I also know that things changed from the original GPS 18
model to the improved GPS 18x. And then, there's 3.20 firmware vs
other firmware to bring into the mix.
I still have the older GPS 18 somewhere. I'll try it to see if
there's a difference.
