Even though we can tell (most of the time) from a station's ICON the type of station they are, a set of standards have been devised that links the SSID (the number part of the callsign) with the ORIGIN of the beacon. These standards apply globally.
For example, VK3EFG has a TinyTrack setup with the icon as a CAR. When we see this station on the map we know that it is a car, however how dod the beacon get into the network? Using the standard SSID table below, we could tell this information easily by looking at the callsign:
- VK3EFG-9 would indicate a standard VHF mobile setup.
- VK3EFG-6 would indicate that the station is sending APRS via the ARISS satellites
- VK3EFG-15 would indicate that the station is operating HF APRS.
- VK3EFG-7 would indicate that the station is using a Kenwood D7 Handheld, and therefore LOW power.
Here are those common defaults:
|-0 (No SSID)||Home Station|
|-1||Digipeater, or Home Station running a Fill-In Digi,|
|-2||Digipeater [#2] on 70CM|
|-4||HF to VHF Gateway|
|-5||IGate (Dedicated system, not home station)|
|-6||Operation via Satellite|
|-7||Kenwood D7 Handheld|
|-8||Secondary Mobile usage (also Maritime vessels) (VHF / UHF)|
|-9||Mobiles (VHF / UHF)|
|-10||Operation via Internet Only (No RF capability)|
|-11||is for APRStouch-tone users (also high altitude balloons)|
|-12||Portable Units such as Laptops, Camp Sites etc|
|-15||Operation via HF|
As always, these are only a RECOMMENDATION, however it would be appreciated if these standards could be followed as much as possible.
