Is there anyway to get any APRS client to not Igate a packet with a path of ARISS in it. I run a satgate here in NJ and the donut effect is causing problems for several hams in the area that can't get a packet Igated after it is digi'd by the ISS because it's a dup. My Igate hears the first packet direct that then causes the ISS digi'd packet to be a dup. It would seem to be a simple thing to set a filter to ignore a path of ARISS, and accept everything else. I would think that this would fix the problem of people who want to run Igates, but don't because of this. I recently moved to Florida for the winter and had to shut my igate down in NJ for this reason. Also, I noticed when down there that there is a lack of satgates along the eastcoast. ISS,PSAT, and PCSAT are hearing stations fine but no satgate's available until the bird's footprint move well inland.
