D-PRS Setup for ICOM D-Star Radios

Turn on GPS mode.

Set the strings to $GPGGA and $GPRMC only.

Choose a D-PRS symbol and use the DPRS Message Calculator and then enter the contents of the box
"Input into TX Message C1:" into the GPS message on the IC-2820 and IC-91AD or C1 channel on the ID-800H.

Set the beacon rate to zero.

Set your RPT2 in the callsign menu to allow for gateway operation. (ex: W1IXU  G)


Notes:
While any radio is in either GPS or GPS-A mode, it cannot be used for standard low speed data.

The GPS-A "format" does not support altitude (/A=000121 for instance).
For your altitude to be seen, you will need to run in GPS mode with the RMC and GGA strings enabled.

You must set your RPT2 to allow for gateway operation otherwise you will not be gated through APRS-IS.

To check proper operation, go to the jFindu D-PRS Activity web page and you should see your callsign & data listed.

If you're using an SSID, make sure that it is in the eighth position in your radio's callsign memory (ie: WY1U   M)
The G2 Gateway Software does not allow for numered SSID's. You must use a letter!

For more info please visit AE5PL's D-PRS page.

Waterproof external GPS Antenna for IC-2820

The Gilsson part #MCX Amplified GPS Antenna with 90 degree MCX connector can be used in place of the non-waterproof GPS antenna that comes with the UT-123.

Notes:
You will also need a Female-Male MCX adapter that has a straight MCX male connector body that will fit thru the case of the IC-2820 into the external GPS jack.
