Connecting the radio
Open the Radiooddity CPS and connect the radio to your computer.
Make sure the downloads linked above are for the correct model and version of your radio!
Finding the COM port
You can find the COM port by going to device manager (Windows Key + R > devmgmt.msc) and checking the devices under Ports (COM & LPT).
It’s a good idea to save the config from the radio before making any changes. There are two ways to save in the software.
File > Save will save (and overwrite) the file you have open.
The Save button will open a prompt which will let you save the config as a new file.
Change Your Call Sign (red “1” in the screenshot below) to your call sign. Do not add an SSID.
The Your SSID (green “2”) setting may need to be changed depending on where you’re using the radio.
See this link for a list SSID recommendations.
The APRS Map Icon symbol (orange “3”) will change the icon that will appear on the map.
See this link for a table of icons.
Change Your Sending Text (blue “4”) to the message you’d like to send.
You must have this channel selected to send APRS data.
Setting APRS on radio
You can enable or change APRS modes on the radio by pressing the knob to open the menu then select
appendix > APRS > APRS Type > select type (below)
Write to radio
Save your config (see saving options above) and click the Write button to write the config to the radio.
You may need to turn the radio off and back on for GPS to start.
You will see a flag icon in the top bar when you have a channel selected with APRS enabled.
It may take longer than the APRS Auto TX Interval to send the packet. The Transmit Delay and Prewave Time settings can also add delays to the APRS interval.
You can search for your callsign at aprs.fi to check if you’re being heard by nearby stations.
Search the raw packets page to check for errors if everything looks correct on your radio. You may have an incorrect icon or map symbol.
