Okay, I think I have APRS down, but feel free to explain it in 1st grade terms just in case I don't. From what I gather, I can get a TinyTrak, configure it using a null-modem cable to my computer, then disconnect, hook it up to my GPS, and run a cable to my handheld. From that point, the GPS transmits the coordinates to the TinyTrak, where they are coded and sent to the radio. The radio broadcasts the signal, which is then picked up by, decoded, and someone can see where you are.
For the decoding, I understand that you need a scanner or receiver to monitor the freq, and then a patch code to deliver the sounds/codes from the scanner to the laptop. Software on the laptop then decodes the message into usable grid coordinates. If you're lucky enough to be transmitting your packets through a gateway, the tracking party doesn't need the scanner, just an internet connection.
My question (one of many) is that how does this work while I'm traveling cross country? The wife is planning a trip back to the States and I want to monitor her progress using APRS. When she's broadcasting the signal, I just don't get how the repeater knows how to pick it up or how the radio automatically moves to the next repeater. Basically, how does this work if she's too far away for my scanner/receiver to hear her transmission?
Also, is there a way to see which repeaters cover which routes so I can "tweak" her route based on where there's coverage?
Thanks in advance!
