Callsign settings

This section explains how to set up GPS TX MODE (DV-G), not GPS-A, so your position will be shown on other D-Star transceivers & the APRS servers.

To set up your IC-E2820 & IC-E92D to use GPS (DPRS) mode you will need to create a checksum code to enter in the GPS message in the 2820 & the 92, this can be done by using the D-PRS Calculator created by Pete Lovell AE5PL.

To set up your IC-E2820 to send GPS Data (DV-G) you need to set the following parameters,

MENU > DV GPS >

GPS SENTENCE = RMC & GGA on, all others OFF

GPS TX = GPS (not GPS-A)

GPS AUTO TX = OFF (GPS data will be transmitted when you press your PTT)

GPS MESSAGE = (enter your checksum code created by the D-PRS calculator)

When your 2820’s GPS is receiving a valid signal the GPS symbol will stop flashing (this can take sometime) so when you press your PTT valid DVG information will be transmitted.

To set up your IC-E92D,

MENU > DV SET MODE > GPS TX MODE = GPS > SENTENCE = RMC & GGA = ON, all others OFF.

> GPS AUTO TX = OFF (GPS data will be transmitted when you press your PTT)

 MENU > MESSAGE/POS > GPS > (enter your checksum code created by the D-PRS calculator)

On your  92’s display you should see DV-G, and when the light is flashing (GPS lock) on the HM-175GPS speaker/mic and you press your PTT then you will be successful transmitting DVG.

The Checksum code is unique to the callsign & the APRS symbol that you select in the D-PRS Calculator.

By setting my GPS TX MODE to GPS and not GPS-A position data will be seen both on other 2820’s & 92’s (and worldwide through the D-Star network) and the APRS servers such at APRS.fi

DO NOT use Auto GPS beacons through the repeater. DStar transceivers wait until the frequency is clear before transmitting GPS information. This sounds ideal but in practice if a beacon collides with the next users data header it can stop their transmission from being passed through the repeater and or the Gateway onto the network.

Not all countries allow use of reflectors, in which case you will need to select the reverse path on your radio using the “one touch reply” feature on your radio
