50
and 70 MHz opens to allow cross-band transatlantic contact
On Monday, June 25, there was a big opening to Europe on 6 meters (50
MHz), also known as the 'magic band'.
In most areas, the opening started in the local US mid-morning, lasting
until dark.
According to QST column author of 'The World Above 50 MHz' Gene
Zimmerman, W3ZZ, "Many areas of the country that do not
normally work Europe, including the Midwestern states, West Texas and
Colorado, worked stations in Europe.
"At one point near the end of the opening, stations on the East
Coast of the US were working stations in Hawaii on the Big Island."
In this opening, Mike Smith, VE9AA, in New Brunswick
was on 50 MHz when he worked Nigel Coleman, G7CNF, on
CW cross-band; Coleman was on the 70 MHz band (4 meters) in England.
Zimmerman said, "Though a few cross-band contacts were made via
F2 propagation during the sunspot maximum period in the 1970s, this is
believed to be the first 50/70 transatlantic cross-band contact ever made
on multi-hop sporadic-E propagation."
RSGB VHF/UHF Manager David Butler, G4ASR, concurred:
"It certainly isn't the first United Kingdom-North America 4 meter/6
meter cross-band QSO, but it probably is the first via multi-hop sporadic-E."
In North America, 70 MHz is channel 4 on television sets.
