I've recently learned that the Kenwood APRS radios have something called 
a "DX" list.  Does anyone know what the packet format is to put 
something in this special list?  Is it simply a symbol of /% (DX 
Cluster) or \d (DX Spot) or both?  Is there anything out there that 
actually generates such packets and what are the guidelines around such

PS.  I did see "DX CLUSTER Live last two hours worth of DX spots plus 
information on DX." on http://www.aprs.org/, but the link to 
http://www.ew.usna.edu/~bruninga/dxspots.html doesn't work any more.

PPS.  http://aprs.org/astars.html talks about satellite schedules 
showing up in the DX-LIST and/or DX-SPOT, but again, nothing definitive 
about the packet format to put stuff there.

PPPS. http://homepage.ntlworld.com/ajmckinnon/aprs.htm mentions "A 
modification of this is a "DX query", which again sends a different 
ASCII code to which the other system replies with information of the 
best DX in its current station list, ignoring stations heard via 
digipeaters.", but still no details.  If you're going to go so far as to 
say "different ASCII code", why not just say it's a "?APRSxxxx" and 
provide the detail?
