This is not relevant for the output frequencies of the system where the LRRP data is lacking and probably not really useful.

I noticed that LRRP data is sent when the SrcPort is the traditional 4001 (LRRP) port, but also in other cases where the SrcPort is some kind of random(?) number. I find it by looking at the packets and finding my raw Hex Lat and Lon values that I get familiar with when skimming the packets.

Hopefully the authors of DSDPlus Fastlane (and DSD FME, @lwvmobile , and SDRTrunk, @DSheirer ) can automate this long process of manually calculating the location, and showing it on a map.

I based my findings on the thread DSD+ I can see LRRP and ARS. Why there are no GPS positions? and especially on the entries DSD+ I can see LRRP and ARS. Why there are no GPS positions? and DSD+ I can see LRRP and ARS. Why there are no GPS positions? and the pics from the users @SignalPatcher and @G125. For example, this is probably relevant to DMR LRRPs:

This is my P25 data, for example, and obfuscated a bit for privacy reasons:

In my case:

34 is the indication of Date.

1F9EDEEA39 is the Year Month Day Hour Minutes Seconds (I think). I did not get an accurate result (maybe the clock in the P25 system is incorrect) but you can see that if you convert this Hex value to Dec value, for example at Hexadecimal to Decimal Converter you see that the Binary representation of the first 11 digits (11111100111) is 2023 (which is the current year).

66 is the indication of the Location.

You take the first value, convert it from Hex to Dec, multiply it by 180 and divide it by 4294967295, and you get the Lat (at least in my part of the world).

You take the second value, convert it from Hex to Dec, multiply it by 360 and divide it by 4294967295, and you get the Lon (at least in my part of the world).

6B is maybe the indication of the Speed.

I am not sure how this is calculated exactly. (Maybe simply convert Hex to Dec and you get the speed).

56 is maybe the indication of the Direction.

I am not sure how this is calculated exactly. (Maybe simply convert the Hex to Dec and divide by 2 and you get the direction).
