Egg Zackery! My current method is to download the files from my 302A
(CFR) onto the laptop nor PDA, then on the following Monday when I get
home after work*, I upload any/all flights to the OLC.

For OLC League I'm pretty sure you are still are required to have an IGC approve flight recorder, a PDA/PNA/tablet with XCSoar won't cut it.

*I spend Friday afternoon through Monday early AM away from home.
