[aprssig] APRS on HF

[Julian, G4ILO]

Hi Jim.

I don't think I am guilty of this misconception as I am well aware
that APRS is intended for giving information about the local situation
but that was one of the main reasons for my question because you don't
get any *local* information on HF.

I have listened on the Net14 frequency a  couple of times but without
any mobile traffic I didn't find it very interesting as there wasn't
much going on. Once you have sent a greetings message to the other
people who are on what else is there to do? There are other ways to
have such QSO's on HF. I do use APRS messaging a lot on VHF but that
is because I know other local APRS users on VHF so we often have
things to say to one another and in our mountainous area we often
can't talk direct.

In response to Stephen's comment about RX-only gateways breaking
messaging that's true but when considering HF I don't think there are
many occasions when someone wants to message someone they don't know
1,000 miles away. Most of the messages I have seen have been direct
"hello" messages between gateway operators or APRS queries. If someone
is driving through an area beaconing on HF the people on VHF APRS in
the area probably don't even know he is there, and he won't be
receiving any local information over the HF channel (though thanks to
the French cross-band gateways he may be receiving information about
things hundreds of miles away.)

So I'm still struggling to see what the point of HF APRS is other than
allowing people out of range of VHF digis and gateways to get their
position reports into aprs.fi.
