You have needlessly resent completely unrelated messages,  and exposed 
all the "email hacked" victims' addresses back to the mailing list once 
again. 

------------------------------------------------------------------------

D-Star position reports get picked up by "D-Gate stations (often 
co-located with D-Star repeaters), are reformatted into APRS-format 
position, and then injected into the APRS Internet System just like a 
normal APRS igate.   

Note the SSID.    "-C"  would be impossible for normal RF APRS 
operation.  ("Legal" over-the-air AX-25 packet SSIDs can only be in the 
range of -0 through -15.)   However, anything goes for the APRS-IS or 
non-packet RF modes -- any two character combination of letters and/or 
numbers  will work,  when normal over-the-air AX.25 packet TNCs are not 
involved.

For example, the new APRS-over-PSK63 protocol now being used on 30-meter 
HF encourages stations to use "-63" as an SSID,  so that PSK63 stations 
on APRS maps can be distinguished from "conventional" AX.25 packet APRS 
stations on 30m.
