[Logic] More LOTW Questions

[logic@mailman.qth.net]

Thanks to a couple of you I am making some progress.. 

I noted during the upload process that I was getting numerous error.

Many were invalid callsign errors. I think those came from the fact 
that I sometimes enter a "(C)" or "(M)" into the  Logic's callsign 
field to indicate to me that is was a contest or mobile contact...  
Perhaps I need to strip those designations out of my log file???

The other error related to INVALID mode... Most of what I see are 
Pactor entries which I have designated in Logic as "PCTR".. Is there 
a set of standard mode designations that LOTW recognizes????

Thanks for any help forthcoming..
