A transatlantic VHF digital receiver site has begun operation in
Newfoundland. Frank Davis, VO1HP, reports that antennas were erected
and a VHF SDR activated on May 19 to inaugurate the VO1FN
"TransAtlantic VHF Digital Beacon Receiver Site." The receiver site, in
grid square GN37, is sponsored by the Society of Newfoundland Radio
Amateurs (SONRA <>), the Baccalieu Amateur Radio Klub
(VO1BRK <>), and the Upper Trinity Amateur
Radio Club (UTARC <>). Davis made his
summer home and station in Freshwater, Conception Bay North, available
for the receive-only site; it offers an unobstructed view of the North
Atlantic, and he's open to suggestions as to how to take best advantage
of the site's capabilities.

   "The point of this experiment is to provide a North American
receiver online 24/7 that can be used by European beacon operators or
well-equipped VHF stations to test their transmissions," he told ARRL.
"It is a receive-only site, but if it is proven over time that signals
can be heard and correlated with propagation studies, then it might
stimulate operators to equip their stations to attempt a two-way QSO."

Attempts have been made from Newfoundland and Labrador to transmit an
Amateur Radio signal across the North Atlantic on 2 meters, with a
two-way contact as the ultimate goal. The Irish Radio Transmitters
Society (IRTS <>) offers its Brendan Trophy to the
operators of the Amateur Radio stations to establish the first two-way
communication on 2 meters between Europe and North or South America.
The most recent effort to snag the Brendan Trophy took place from VC1T
in Newfoundland in 2014. Interest stemming from that experiment led to
the VO1FN project.

"The receiver site is up and running using an SDR and SDR Console
software," Davis told ARRL. He explained that users would first have to
install SDR Console V2.3, and he would open a free account permitting
them to log in.

"We are willing to rotate the Yagi array in any direction for testing
with distant 144 MHz digital stations," Davis said. Read more
