[OZAPRS] Alpine Rally - APRS & RF conditions

Wed Nov 28 07:50:39 EST 2007

There is no problem.  What I dont like is one particular person assumes  
authority of "Big National APRS Network", just because the network he is  
in has just moved over to the "National APRS Frequency".  When they were  
on 144.9, he couldnt have cared less..  He complains of the effect  
Tasmania has on Victoria, but has he ever considered the reverse?  We were

here first.. :P

Dion.
