[VHFcontesting] LOTW and Rover Ops

[N3AWS at aol.com]

How can I get the LOTW to record my grid square when rovering so that others 
can get credit for the square?

I am still struggling with my mobile log from the Florida QSO Party where I 
activated 16 counties.  

Could I sign my call as N3AWS/XXX for the county abbreviation or would that 
require 16 different authencity certificates?

Appreciate all answers!
