ARLA/CLUSTER: Novo recorde digital via EME em 2 metros ( 18 383 Km / JT65b)

[Carlos Mourato]

> Allan, ZS1LS, and Jeremy, W7EME, in Hawaii established a new SARL EME
> record on 144 MHz.
>
> The contact took place at 20:20 UTC on 3 August 2011 using the JT65b
> mode and covered a distance of 18 383 km.
>
> The contact was established during a small window close to moonset in
> South Africa and only 0,7 degrees of moonrise in Hawaii.
>
> Signal reports varied between -26 dB and -31 dB at Allan's QTH. Jeremy
> copied Allan at -21 dB on the night before but Allan could not copy

> WSJT is a computer program used for weak-signal radio communication
> between radio amateurs. The program was initially written by Joe
> Taylor, K1JT, but is now open source and is developed by a small team.
> The digital signal processing techniques in WSJT make it substantially
> easier for radio amateurs to employ esoteric propagation modes, such
> as high speed meteor scatter and moon bounce.
>
> Congratulations to Allan and Jeremy.
