GPS beacon call

GPS (Global Positioning System) is a system for displaying

the geographical location of a station. GPS receivers pick up

latitude and longitude coordinates from passing satellites.

A GPS beacon call obtains the global position of another

station.

When a station receives a GPS beacon call, it automatically

transmits the GPS information. The operator is not alerted

that a call has been received. For example, a transportation

manager might send a GPS beacon call to locate a mobile

station such as a delivery vehicle.

If the station you are calling has set up a privacy key, you

will need to set up the same privacy key in your transceiver to

be able to receive GPS information from this station.

Before you can send a GPS beacon call, you need to:

• enable GPS calling (refer to the HF SSB transceiver

reference manual, Chapter 7, Password entry to enable

transceiver options)

• make sure that the station you are calling is also set up

for using GPS

• check if you need to match the other station’s use of a

privacy key (refer to the HF SSB transceiver reference

manual, Chapter 5, Call privacy on/off)

• set up your address (refer to the HF SSB transceiver

reference manual, Chapter 8, Selcall address setup)

• set up a channel for selcalling (refer to the HF SSB

transceiver reference manual, Chapter 3, Channel

creation and editing).
