I just saw Hesu's name associated with some kind of DX cluster
code.  Is he the author of one of these?

Ah, such is the state of Ham radio.  It's the same in APRS, with
40,000 users, maybe only 00.1% actually send a message...  But
it's a capability, and it has value when needed, so I say we
should make the capability there to crossconnect as many
directed-text messaging systems as we can.

There are two approaches here:
1) As you say, the originator on CC has to set a flag for it to
go to APRS.
2) CC could watch any message to callsignXXXX and if
callsignXXXX exists in APRS, then send the message on the

Eventually, I prefer #2, sin ethe goal is anywhwere, anytime,
using any device, getting a message to any station by callsign

Please pass this on to VE7CC and I have copied Hessu on this
email to see his comments...

The opposite direction is equally important.  If CC-cluster
could watch the APRS-IS for messages and if it sees any that are
directed to any of its CC-cluster users that are currently
logged in, it forwards the message to him...  I can see that
valuable for th eguy who gets home, turns off his APRS rig and
goes inside to work some DX and an APRS person sends him an aprs
message.  It should get to him on this Cccluser console..
