Falta dizer que esses 18383 Km deve ser a distância entre estações, porque o sinal ir à lua e voltar é muitissimo mais. <div><br></div><div>73 de CT4RK<br><br><div class="gmail_quote">2011/8/7 João Costa > CT1FBF <span dir="ltr"><<a href="mailto:ct1fbf@gmail.com">ct1fbf@gmail.com</a>></span><br>

<br>
Allan, ZS1LS, and Jeremy, W7EME, in Hawaii established a new SARL EME<br>
record on 144 MHz.<br>
<br>
The contact took place at 20:20 UTC on 3 August 2011 using the JT65b<br>
mode and covered a distance of 18 383 km.<br>
<br>
The contact was established during a small window close to moonset in<br>
South Africa and only 0,7 degrees of moonrise in Hawaii.<br>
<br>
Signal reports varied between -26 dB and -31 dB at Allan's QTH. Jeremy<br>
copied Allan at -21 dB on the night before but Allan could not copy<br>
him.<br>
<br>
WSJT is a computer program used for weak-signal radio communication<br>
between radio amateurs. The program was initially written by Joe<br>
Taylor, K1JT, but is now open source and is developed by a small team.<br>
The digital signal processing techniques in WSJT make it substantially<br>
easier for radio amateurs to employ esoteric propagation modes, such<br>
as high speed meteor scatter and moon bounce.<br>
<br>
Congratulations to Allan and Jeremy.<br>
