[amsat-bb] LoTW Station Locations

I am planning on beginning my rover operations and need to know how to set up my station locations in LoTW so that I can have a different grid count for each grid I am working from. Just worked AD0HJ yesterday from grid EM57, which is not my home station grid, and need to upload the contact.  Tnx.    HELP!JerryKJ4EUSent via the Samsung Galaxy, an AT&T 4G LTE smartphone
