[Fourlanders] APRS with Rovers?

[Rogers, Ron]

And........
 
we should beacon our data with 1500 watts into an omni-directional antenna for maximum digipeater and I-Gate coverage !!!!!!!!!!!!!!!!!!!!

So let's try and make sure to beacon Friday night and Saturday until right
before the contest. The servers at large will keep our location on file for
hours or permanently. Just so long as we stop beaconing before the start of
the contest we should be within the rules.
