ARLA/CLUSTER: Primeira reflexão de sinais na ISS une a Europa à America em FSK441 após duas semanas de preparação

[João Costa > CT1FBF]

First ISS reflection from Europe to North America

After two weeks of preparation Tim, G4LOH in Helston, Cornwall,
England Grid IO70jc and Roger, VE1SKY Bridgetown, Nova Scotia, Canada
Grid FN74iu used FSK441 to try a Brendan Quest style reflection off
the International Space Station (ISS).

Employing AMSAT satellite software, both stations aimed at the
calculated grid HO11nl for a 144.175 MHz QSO attempt with a mutual
window of less than 1 minute.

At 12:22 UTC May 2, 2016, VE1SKY copied G4LOH at a distance of 4,441
km. The signal decoded once completely by 'cursor clicking' and then
partially. This was the first received ISS signal bounce from EU to
NA, and the first 'intentional' signal by ISS reflection received in
any direction across the North or South Atlantic (screenshot is
available at QRZ.com/VE1SKY). The reception is being verified as a
possible DX record for satellite reflection.

Tim has since been received twice in the much closer GN37 grid by
VO1HP using Morse code.
