I hate to pick at details, but does this mean to not set up digipeaters
on HF, or to not request a digipeat in your transmitted path? It would
seem more like the latter because otherwise there'd be no digipeaters
around even if you wanted to use one for some reason.
And the logical follow-on, based on the response I read from the
European station, is what alias is supposed to be used if a digipeater
is configured, but hopefully only used in extreme duress? I've seen
ECHO documented on HF APRS most often, but I also see that APRS
Messenger is doing some WIDE* stuff and the mention was made for WIDE2
or some-such earlier today.
