A P R S
Automatic Packet Reporting System
I often use https://aprs.fi to view packets that have made their way through an iGate of some kind onto the Internet. My vehicle uses W6KKO-12 via a one-way Byonics tracker. Thus, do not send messages to that -12 ssid. Also avoid my -10 ssid as that is my iGate and does not receive messages.
To contact me I use the w6kko (home), or w6kko-7 (handheld), or w6kko-9 (mobile) ssid. Do not use -12 or -10.
Below is an APRS shortcut PDF I created to help myself and anyone else that needs it. Enjoy it on your mobile device, or tablet. Perhaps print it out on both sides of a paper and laminate it. It is definitely not all inclusive. There are things like SMS that one needs to sign up for and other services that are somewhat redundant. Perhaps grab what you want from my list and make your own. Have fun!
