Howto: Setting up and using D-PRS on Icom ID-5100

Setting up D-PRS on the Icom ID-5100 can be confusing for beginners as the radio has lots of options for D-PRS. Here are some step by step pictures an explanation I originally made for a friend, now for everyone.

We will see hot to properly setup DPRS on the Icom ID-5100. This includes sending your position and local time. Additionally we will see how you can show up on the repeaters “Heard Directly” section on aprs.fi

Since the 5100 shares a similar menu structure as other newer Icom radios, this procedure might also be used on the ID-51 or ID-5100.

Selecting the internal GPS

We first need to tell the radio to use its internal GPS.

Setting the right format and information

Now it is time to setup the position format and what we’ll send along our position. An interesting feature is to send your local time along with your position. However we will not discuss how to set the radio’s clock.

Selecting the right SSID

TL;DR; Too long did not read. Simply select -5 or -12 to indicate other two way APRS users you are not a two way APRS message capable station and that you are originating from another network. More on APRS SSIDs, read here.

Long Version. I have been dumb using -9 (my APRS station and DStar would share the same SSID) and was wondering why my messaging capabilities from my mobile APRS setup was not working. SOmetimes I was unable to receive messages.

This was partly caused by the fact that APRS messages addressed to me sometimes ended up being routed to the repeaters gateway which acts toward the APRS-IS network as a gateway. Hence the repeaters gateway does not know how to handle this, the message was dropped. So now I stick to -5 or -12.

Appear on “Stations heard directly” list

This is a useful trick every repeater sysop will be thankful for if you activate it.

Now you will appear in the “Stations heard directly” on aprs.fi. Here an example of our club repeater.

This will also provide input data for aprsdirect coverage maps.

Sending D-PRS

At last but not at least we need to tell the radio to send D-PRS each time we key up. This pretty easy.

Receiving D-PRS

Whenever you receive D-PRS data a popup will come up on the screen showing you some of the details of the remote station.

However, it is possible to show more information. Depending what the remote station has set, you will see various information. Note the remote stations local time in the lower left corner of the display. This goes as follows.

Conclusion

Thanks for reading, I hope everything is clear despite being very clear. Let me know in the comments what you think or what needs to be clarified.
