Cool Holger, I didn't know you were a ham also. I have a dual band rubber duck antenna on the belly of my Alon that works great to track with APRS too through a Kenwood TH-D7 handheld. It works great, and constantly puts out heading, altitude and speed readings every minute. Have used it to Oshkosh and back and found tracking worked almost 100 percent of the time across the US. Even when I forget to bring along the radio, I find that the Android the APRSDroid app works almost as good transmitting packets through the cell data up to at least 5k feet.Marty WA7HOI

....I was listening to one aviation official who said the idea of a successful hijacking resulting in a successful landing at some secret location is absolutely preposterous.
