Hi David and all,
In the past there were a few HF gateway stations about that were'nt directly
connected to the internet. I have in the past been in this category myself
however It would be nice to know, who / if there are any HF gates still
running that dont have a direct connect to the aprs-is ? Hence the
recommended use of GATE,WIDE2-1 for HF mobiles.
And .. we ( VK5 ) have also done a resaonable amount of testing on 40m for
possible HF APRS use back a few years ago. Similar time frame to what Brian
was alluding to in his email. At that time we didnt have much success either
on 40m, alaways going back to 30m, with perhaps 20m as the second choice. I
reckon the main problems were daytime noise levels at the HF gates, along
with some funny multipath stuff. Anyway It'll be interesting to see how 40m
performs for you this time around. Like you say it would probably be a good
option in the long run.
Regards .. Andrew .. VK5EX
