== Regional Information Pages ==
As with many systems in amateur radio each local region will develop their own customs, practices, protocols, etc. This page is intended to act as an aggregation point for subpages which offer insights into regional APRS operations, local SSID customs, digipeater/IGate siting strategies, etc.

Stub for recommendations on setting digipaths (aka unproto paths)

IMPORTANT : We need information on recommended settings for all regions, and links to understanding new paradigm information.
RECOMMENDATION: Most of this regional info should be transferred to the new [[RegionalPages|regional info pages]] and content added there about local protocols.

== Recommended Path Settings for: ==

=== '''''MOBILE''''' Stations in North America (VHF) ===

* WIDE1-1,WIDE2-1 :Two hops in all directions with potential to use fill-in digis. Best path for mobile use in most all areas.
* WIDE1-1,WIDE2-2 :Three hops with potential to use fill-in digis. Use only if truly needed while very far from any mountain digis or cities.

=== '''''FIXED''''' Stations in North America (VHF) ===

* WIDE2-1 :One hop... suitable if you are within earshot of a "high" WIDEn-N digi with a large footprint.
* WIDE2-2 :Two hops in all directions... recommended maximum for routine and courteous use in most areas.
* WIDE3-3 :Three hops in all directions... only for very sparsely populated areas far from any mountain digis or cities. Many digis in populated areas will only give one hop to paths of WIDE3-3 (and broader).

RELAY and WIDE and TRACE and TRACEn-N are obsolete.

For details and explanation, visit Bob WB4APR's [http://www.aprs.org/fix14439.html WIDEn-N Paradigm] web page.

=== '''''HF''''' Stations, max routine===
* GATE, WIDE2-1: Recommended for HF APRS, **DO NOT USE** on VHF.

You can see a bad example of path overkill [[PathOverkill|here]].

=== '''''Mobile''''' Stations in Australia (VK) ===

* For VK6 & VK8 use RELAY,WIDE2-2
* For VK1, VK2, VK3, VK4 & VK5 use WIDE1-1,WIDE2-1
* For VK7 use WIDE1-1,WIDE2-2 TASn-n also supported.

* On HF use GATE, WIDE2-1 **DO NOT USE** on VHF.
* On APRS Satellites use ARISS,SGATE,WIDE

Visit the appropriate state's web page at the [http://www.aprs.net.au/ Australian APRS site] for further details.

=== Republic of Ireland ===

* WIDE1-1, WIDE2-2 for Mobile Stations. Three hops with support for Fill-in digis
* WIDE2-2 for Base Stations. Two hops no support for Fill-in Digis. Packets should make it to an Igate.

If you want to discuss/or disagree with the settings/want to try something else, Please contact either EI7IG or EI8JA.

Satellites are subject to doppler shift and you should adjust your uplink/downlink accordingly. Doppler will make the frequency on a LEO shift as follows:
* '''2''' m ±'''3''' KHz (FM capture effect negates the need to adjust on this band)
* '''70''' cm ±'''10''' KHz
* '''13''' cm ±'''50''' KHz

== Automatic Packet Reporting System ==

Also known as Automatic Position Reporting System, APRS is an amateur radio based digital communications system for local, tactical, real-time exchange of information among all members of a net, including map based displays for situational awareness. It was developed by Bob Bruninga, [[http://www.qrz.com/wb4apr WB4APR]], who currently works at the United States Naval Academy.

=== Capabilities ===
APRS is used to transmit real-time information such as messages, bulletins, announcements and the locations of any stations or objects via amateur packet radio protocols. Real-time reporting of station position for mobiles is facilitated using the Global Positioning System. APRS is capable of transmitting a wide variety of data including weather reports, short text messages, radio direction finding bearings, telemetry data, and storm forecasts. These reports can be combined with a computer and mapping software to show the transmitted data superimposed on a variety of map displays.

=== Technical Information ===

In its most widely-used form APRS is transported over the air using the AX.25 protocol at 1200 baud Bell 202 audio frequency-shift keying on frequencies located in the amateur 2-meter band (see [[Frequencies]]). An extensive digital repeater, or [[Digipeater|digipeater]] network provides transport for APRS packets on these frequencies. Internet gateway stations ([[IGate|IGates]]) connect the on-air APRS network to the APRS Internet System ([[InternetSystem|APRS-IS]]), which serves as a worldwide, high-bandwidth backbone for APRS data. Stations can tap into this stream directly. [[APRSIsDatabases|Databases]] connected to the APRS-IS allow web-based access to the data as well as more advanced data mining capabilities. A number of LEOs (low-earth orbiting satellites) and the International Space Station are also capable of relaying APRS data.
