I have made a patch to multimonNG that fixes its APRS behavior, by
removing the "-0" SSID (which is compliant as of APRS101.pdf, but fails
to trigger APRS-IS server dup checkers), and by adding a "*" for all
digis with the H-bit set.
This looks like a sensible compromise to feed data into APRS-IS, and
does not confuse the servers too much (the "*" setting behavior is badly
documented and inconsistent with implementations anyway, so a 1:1
mapping appears to be most sane to me, as it is the only way to
losslessly convert the packet back to AX.25)
I am appending the patch to this email, and will try to get it into
multimonNG upstream soon. If you want to test it, apply it to the source
from http://github.com/EliasOenal/multimonNG and run "./multimonNG -A"
(A for APRS).
