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.
