[aprssig] APRS on Android

[Eric Lorenz K9LGE]

Thanks Lynn...that is what I was trying to say. In addition to 
that...for other mobile users...doesn't do much good to put contact 
freq, etc. into my beacon if they aren't going to see it. Can reverse 
gating be done with filters, rules, etc. to only gate certain traffic as 
to not overload the bandwidth?

Thanks,
Eric K9LGE
