APRS Standards 2017

To help with the flow of APRS location and status information over the APRS network we have set the following standards for the BP MS150 ride. We ask that all stations follow these standards so that they are as affective as they can be when transmitting location packets.

A PDF of these standards is available here: BPMS150-APRSStandards-2017

It is a five (5) step process to properly setup your APRS Tracker and they are outlined below. There is additional information and tips on APRS setup at the end of the page.

1-FREQUENCY

Set the transceiver to the National APRS Frequency.

144.390 MHz

2-STATION ID / CALL SIGN

Set the call sign of your station to either your tactical call (see chart below) OR your FCC Amateur Radio Call Sign with an SSID of 1-15. Your call sign should be no longer than six (6) characters to comply with the APRS standard. If you select an SSID greater than 15 your station will not be digi’ed.

CHOOSE ONE OF THE FOLLOWING
USE TACTICAL CALL SIGN USE FCC RADIO CALL SIGN
_ _ _ _ _ _
(6 Characters Max)
Example: MSAG23 (see below chart)
_ _ _ _ _ _ – # #
(6 Characters Max + Number 1-15)
Example: N0XFD-15

NOTE – If using your FCC Call Sign PLEASE e-mail aprs@bpms150hams.org your selected call sign + SSID and Assignment.

IF USING TACTICAL CALL SIGN – USE THESE NAMING STANDARDS
APRS Tactical Call Symbol Character Vehicle Reference
MSAG## v (Van) SAG Van ##
MBOX## U (Bus) SAG Box Truck ##
MSUP## u (Truck 18wh) Supply Truck ##
MMOT## < (Motorcycle) Motorcycle Marshall ##
MMED## A (Ambulance) Medical Rover ##
MCOM## k (Truck) Comm Support ##
MTOU## > (Car) Tour Vehicle ##
MRM###  (bib #) b (Bike) Ride Marshal ##
##=Vehicle # 01-99 NOTE – All symbols use the Primary “/” Table

NOTE – The use of ‘0’ BEFORE numbers less than 10 is Important

NOTE  Even if you are using your FCC Radio Call Sign, please use the symbols of the standard if they apply

3-DIGI PATH / UNPROTO ADDRESS

Set the digi path or unproto address (it depends on the tracker / software used as to what it is called) of your station to WIDE1-1, WIDE2-1. This dictates how many hops your beacon will make. The APRS coverage along the entire route is good so no more than 2 hops is needed. Use the following path on your tracker settings:

WIDE1-1, WIDE2-1

NOTE – If you are using UI-View32 then your ‘Unproto Address’ is “APRS, WIDE1-1, WIDE2-1”. This is unique to UI-View32 ONLY.

4-TRANSMIT RATE

The transmit rate dictates how often your station beacons. Please set it to no less than 150 seconds. If your equipment does smart beaconing then the speed for the fastest time should be 150 seconds.

150 Seconds

5-STATUS TEXT

The status text on your tracker SHOULD contain your FCC Call Sign if you are using a tactical call sign for your tracker’s ID. This is to comply with your FCC Station ID Requirements.

Example: “N0XFD Charlie – BP MS150 COM 2”

NOTE: Change “N0XFD” to YOUR FCC Call Sigh
