APRS Tips

TIP #1
From: Joe – K3JV Mar 8, 2006

Here are some suggestions for setting up your TinyTrak3 (TT3) so that your home station or other APRS stations that are FILL-IN Digi's will repeat your packets. Having a FILL-IN Digi's repeating your packets improves the probability of your position packets being heard by the local APRS RF network. Once your packets are distributed in the local APRS RF network they will likely make it to an I-Gate and be available on the internet for others, without a direct connection to the
local APRS RF network, to see you. Try setting your "Digi path" in the TT3 as follows: WIDE1-1,WIDE2-2. If you have the capability of running UI-VIEW from home you can enhance getting into the local APRS RF network from your portable tracker by usuing your home station as a FILL-IN Digi. This reference will give you the details on setting up your UI-View as a Fill-in Digi http://nwaprs.info/uiviewdigi.htm

Here is a reference to an excellent source of APRS info. Information regarding set up of portable trackers is well worth the read. http://www.nwaprs.info/mobilesettings.htm

''UI-View32 Setup & Configuration - Important note:''
In the "Setup, Station Setup" dialog, the field labelled: "Unproto Address": It's very easy to overlook erasing the leading "APRS" while editing this field during setup. Full explanation is below and was derived from: * [http://webs.lanset.com/wa8lmf/aprs/UIview_Notes.htm]

APRS DESTINATION & PATH Confusingly Combined in Setup: Not a changed standard but a quirk that confuses many newcomers to UIview. Unlike every other APRS program and Kenwood TH-D7/D700 radios, UIview combines the destination (normally APRS ) and the digipeater path (normally something like WIDE2-2) into a single string in a single field labeled "Unproto Address" in the "Setup, Station Setup" dialog. It's very easy to overlook erasing the leading "APRS" while editing this field during setup. This string must look something like
" APRS,WIDE2-2 " or " APRS,WIDE1-1,WIDE2-1 " . The entries must be delimited by commas. No spaces are allowed.

At run time, the item to the left of the first comma is taken to be the destination. Subsequent items to the right of the first comma are interpreted as steps of the path. If the leading "APRS" is left out, the program will try to transmit to a destination of "WIDE2-2" (or whatever is in the first position) instead. Since APRS applications and digipeaters normally only respond to a destination beginning APxxxx (and a very few other prefixes), you won't be seen on other peoples' programs. And you won't be digipeated.

Note that this combined destination and path entry is strictly a UIview setup-screen idiosyncrasy. All other APRS programs and APRS devices provide separate fields for destination and path entries.
