SSID Guidelines for APRS

Since there are 20,000 APRS users on the air, the APRS maps and data can get very cluttered.  Also, most operators have multiple stations on the air, such as their HOME, CAR, BOAT, and HT.  It is very convenient to be able to recognize these typical applications at a glance.

Here are those common defaults:

-0 Home Station, Home Station running I-Gate.
-1 Digipeater, Home Station running a Wide1-1 Digi, WX Digipeater
-2 Digipeater [#2 or] on 70CM
-3 Digipeater [#3]
-4 HF to VHF Gateway
-5 I-Gate (Not home station)
-6 is for Operations via Satellite
-7 Kenwood D7 HT
-8 is for boats, sailboats and ships (maybe 802.11 in the future)
-9 is for Mobiles
-10 is for operation via The internet only
-11 is for APRS touch-tone users  (and the occasional Balloons)
-12 Portable Units such as Laptops, Camp Sites etc.
-13 Not assigned
-14 is for Truckers
-15 is for HF

Setting Up Your Kenwood D700 (and probably D710) to Act as a TEMPn-N Digi

APRS is a tactical-real-time-local digital communications network designed for rapid deployment in the field using come-as-you-are equipment for a LARGE number of simultaneous stations.  APRS is PERFECT for Field Day with HUMAN operators at all stations. This is not at all what most APRS users are familiar with on a 24/7/365 basis.  Too many people think APRS is only vehicle tracking, and they are so wrong.

For example, the ARRL Field Day rules make it difficult to use APRS on Field Day because the APRS System on that Day must include one temporary and portable digi and be independent of the existing global APRS infrastructure.


TEMPn-N is an ALTERNATE APRS emergency network and digipeater alias that uses the THOUSANDS of D700 MOBILES FOR TEMPORARY Digipeaters.  Although we have about 1000 permanent digis across the USA, we are overlooking the value of the THOUSANDS of mobile D700’s that can act as digis in an emergency if needed.  The problem has always been that we do NOT want mobile digis 99.99% of the time, but it is a shame not to have them available when needed.  The solution is to simply turn them on as digis ALL THE TIME, but only to support the path of TEMPn-N.  This makes them always out of sight, but always useable if needed. (including Field Day!).  This gives those remote D700 emergency digipeaters a standby-ready-to-use-anytime system on not only the national APRS channel, but any channel at any time… without any prior action by the owner.  Here are the two settings to enable permanent TEMPn-N mobile digipeating support in your mobile.  You must use a PC via the serial port to make these settings.  The radio will remember these settings:


MOBILE WIDE1-1 SUPPORT: The above TEMPn-N settings are independent of the front panel APRS menu functions for digipeating and thus can be used by any other mobile operator by changing his outgoing path.  But there are times that owners of D700 mobiles want to activate their mobile to serve as a temporary fill-in digipeater for existing users of existing paths.  To do this, they need to save two APRS MENU items:


By storing these parameters in a PM, they are always available, but also always off to prevent channel QRM.  But for any special application, the mobile can simply turn DIGI ON from his front panel, and then his vehicle will support the WIDE1-1 function temporarily.  When he turns the radio off, it will revert back to DIGI OFF.

AUTO-PM-STORE Must Be Set to OFF: Remember, that the D700 has a special command under the RADIO-DISPLAY Menu that unfortunately defaults to ON.  This command AUTO-PM-STORE defaults to ON and will re-save everything you do on the front panel each time you use the radio.  This overwrites any special settings you have saved in a PM.  For most normal amateur operations, users want to pre-program the PM’s for special settings and then always revert back to those settings each time the PM is pressed.  To make sure this happens, you must permanently set this menu item to OFF!.
