Echolink DOES have an APRS status-reporting function in it that can beacon the
node's presence and whether it is currently active or not.
The problem is that, as implemented, it is essentially useless! It assumes
exclusive command-line control of a classic TNC2-style interface. There is no
easy way to interface it's TNC access, along with other APRS applications, to a
single TNC. You have to use an entire second hardware TNC & radio, separate
from any other APRS setup you have. Further, there appears to be no way at all
to use a freeware soundcard "soft TNC" like UZ7HO, Direwolf, etc (all of which
present only AGWpe, KISS or KISS-over-IP interfaces).
Nearly a decade ago (!), I actually wrote the author of Echolink. I suggested
adding either a KISS interface (so it could be used with inexpensive new-gen
no-command-line TNCs like TNC-X, TinyTrack 4, Opentracker, etc), or an
AGW-Packet-Engine-style interface (so it could use the TNC-sharing capabilities
of AGWpe that allows multiple APRS applications to use one hardware or
soundcard TNC simultaneously). I never got back any response whatsoever.
I suspect Echolink, like so many other ham applications from the "Windows XP"
era of prolific ham software development (early 00's to early 2010s), is now
The most recent version of Echolink is copyrighted 2007 -- now a FULL DECADE
without updates. (Through it DOES WORK on Win7/8.x/10 x64.) ]
