Prezados.
Depois do mail do Miguel "Leiam isto... se for verdade e histórico !" andei a fazer algumas investigações a para já consegui isto (ler o comentário em inglês mais abaixo).
Atenção, que está a decorrer um grande debate (últimos n.º da CQ Amateur Radio - secção VHF Plus" sobre o tema e em principio só serão considerados contactos por fonia e comprovadamente por esporádica, os chamados contactos " puros " (aqui é que a porca torce o rabo, não é Mourato) pois já existem relatos pontuais utilizando vários modos digitais e CW de alta velocidade (manual e por maquina) onde as suspeitas sobre propagação por MS e RL são mais que muitas.
Fantástica é a analise que o Joe Taylor-K1JT(o pai da criança) faz ao comentário de Peter-SM2CEW sobre as potencialidades do JT65 onde este ultimo menciona o estudo do Klaus-DJ5HG onde comprovadamente se conseguem contactos com SOMENTE 10 BITS de informação (equivalente a 2 caracteres) utilizando o JT65.
Portanto, tudo em aberto para o derrube da barreira do primeiro QSO Transatlântico "puro" e da atribuição do Brandon Trophy.

**************************************
Transatlantic 144 MHz signals: Two-meter transatlantic signals have apparently been received on several occasions, but there have not yet been any contacts in spite of several attempts. A number (most??) of these attempts have been poorly planned and executed. A few were better attempts. But the Brandon Trophy still waits for the first confirmed contact.
At this time it is known that there is one ongoing test, and two others are in the works. (Each of these tests is a very different attempt in the path, means of propagation, etc). There occasionally are other tests, unnannounced because the chance of success is small. But as more serious, knowledgable Amateurs take up the challenge, the chances of the first transatlantic contact improve.
We are thinking about another page, giving details on any upcoming tests or requests for stations to assist, and results. Or, if a group desires to keep their attempt quiet, only what they request would be announced. Would a Transatlantic Hot News page be of any value? Certainly not without some carefully planned transatlantic attempts.
If you are involved or are going to be involved in a serious transatlantic test and would like some brief information publicized here, let us know.

Hi Jerry,
Can you confirm that the contact took place?
If so I'm sure the RSGB VHF committee would be very interested as it would
be both a "first" and a 2m distance record.
See their lists etc. here

Some years ago, I worked a GW3 on 2M CW from south of
Buffalo, NY with 15 W (Yaesy FT 221R)and an 8-Element
beam about 20 feet high. I heard him calling CQ on
SSB, but could not het back to him that way. He heard
my CW, and we made the contact. Time was ~8 PM as I
recall, and it was dark outside, but I dont remember
the time of year - it was not summer, tho. I would
have to dig back in my old log books to tie this down.
There was a very large storm over the north atlantic,
and covered New England to Old England from the sat
pix, but ended a good 400 miles (600 Km) east of my
location.
Signals were steady but weak at first, then wobly,
then gone. I dont know if this was Tropo, some kind
of E or what. This remains my best ever DX on 2 M in
over 48 years of hamming on that band. I have worked
repeaters along the Gulf Coast and Florida with a
handheld and rubber ducky during the mormal Major E
season in June, but not Europe since.
