Ciao Renzo,
Thank you very much for your answer. We were aware of your world record
of 304 km in 2007, that's why we wanted to evaluate permanent links of
200-250km. We moved the talk to "44net-fr" mailing-list, and we may
attempt a first 200km link between Bastia and south-east of France soon.
During the last century, Corsica was a bridgehead in the Mediterranean
sea, with 9k6 packet-radio links to France, Italy (San Remo) and
Sardinia. Do you think there could be volunteers in Italy and Sardinia
to establish permanent links with Corsica with modern 44net / upcoming
"NGN" technologies ?
As said a few posts ago, having such links with precise monitoring and
measurements could improve our collective understanding of atmospheric
effects and impact on SHF digital links, and could benefit from ARDC
grants. I think it would be a nice technical and scientific challenge...

Ciao Toussaint,
first of all, sorry for being late in my answer.
I was involved in the working group who established the record of 304 km during the first
experiments in the first months of 2007
(https://www.cisar.it/index.php?option=com_content&view=article&id=3…)
and then improved the bandwidth of the original link with the collaboration of a
notorious brand in the 2016 (https://en.wikipedia.org/wiki/Long-range_Wi-Fi#Italy)
If you like, please consider both myself as first point of contact for old memories and
Gian Leonardo Solazzi IW2NKE as coordinator of nowadays WiFi working group of Italian
CISAR association if you have any specific question about our unforgettable and wonderful
experience about the WiFi longest ham radio world record.
Ciao from Italy.
