Using SignalTrack

When SignalTrack is receiving a bearing from a fixed site the measured bearing and the receiver S

meter reading will be displayed in the Bearing and S-meter display bar near the bottom of the display.

Mobile sites when registered appear as triangles with the head of the triangle pointing in the

direction the mobile is heading and with a small red or gray dot in the middle. When direction

finding within the same band as the radio modems, the amount of time the radio modem is

transmitting is limited (typically once every 5 seconds (see "Networking Mobiles" on page 56)).

Therefore, the data received from these sites is typically spread over the interval between

transmissions. SignalTrack displays each of these bearings bled in over a 400 ms interval (may be

changed in the in the options dialog) and then holds the last bearing received. Each of these

bearings is used to update the estimates made previously by the fixed sites. These updated estimates

are shown in a different color that is selected in the options menu. If the frequency being used is

more than one octave away from the radio modem frequency the polling time is increased so the

estimated locations are updated more frequently. The dot in the center of the site icon changes

color when the site data is received.

Other SignalTrack sites supplying data as slaves appear as diamond shaped sites and their data is

factored into the position estimate.
