Ah. Thanks for the info, Randy. I was hoping to find an RF-accessible DX cluster in my area, so I could monitor or connect to it from the Scouts' campground (where I don't have a landline Internet connection). Lets hope my mobile Internet hotspot can reach
some towers from camp.

That status packet isn't DX in the same way as a DX cluster posts DX spots.
<div><br>
</div>
<div>That packet just mean that KV3B-1 was the most distant station that was heard directly on the frequency at whichever station generated that status packet.</div>
<div><br>
</div>
<div>DX clusters take input from stations that are working DX stations and contain the call and the frequency that the DX station was contacted/heard on. It will give you an idea of what DX stations are heard and where based on the call of the station submitting
the spot. </div>
<div><br>
</div>
<div>Most DX clusters are connected to via telnet session or software these days instead of over packet links.</div>
<div><br>
</div>
<div>
<p style="color:rgb(0,0,0);font-family:'Times New Roman';font-size:medium">Once you establish a connection, you should immediately start to see DX Spots from all over the world. A DX Spot looks something like this:</p>
<p style="color:rgb(0,0,0);font-family:'Times New Roman';font-size:medium">DX de K1BI 14190.0 JA1ABC 20/9 big signal 0750Z</p>
<p style="color:rgb(0,0,0);font-family:'Times New Roman';font-size:medium">the spot tells you that K1BI worked JA1ABC on 20m (at 14.190MHz) at 0750 Z. Want to work the JA too? Just dial up the frequency, listen for him and then call him. That's all there
is to it - </p>
</div>
<div><br>
</div>
<div>It takes a little getting used to, but once you get the format, you can interpret it ( or, in your case, probably write a java program to parse it and make it look pretty. :) )</div>

<div>I already read that document. It talks about the views in APRSdos and how to configure it to handle PacketCluster messages, but it doesn't explain the protocol syntax of the packets themselves.

<p>If so, where can one find the radio protocol specification for it? I'm trying to get ready to support the Boy Scouts' Jamboree On The Air, and would like to have a way of finding them some "good" stations to talk to (not being an experienced HF DXer myself).
So I can use all the help I can get.</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>I can see APRS packets that look like</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>>151803zDX: KV3B-2 14mi 313° 18:01 3857.05N 07652.41W</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>but how do I interpret this? Which station is the DX, and what frequency are they on?</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>Are there other packet format within APRS for DXcluster reports? Are other non-APRS packet protocols for DXcluster documented anywhere?</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>Thanks in advance.</p>
