I dont know if this is an error... but I have tried to use the gps utm converter and it looks like it gives the wrong value in latitude. I have tried this in two different programs with the same error. I My degrees on latitude is about 36 which should return a dec about 36 but it returns somethink like 64000. This may be picking up the wrong value from the serial string. Has anyone else run into this. The longitude seems to work ok. I am using a hp6515.
