ARLA/CLUSTER: Sinal canadiano com 10 µW ERP emitido em 8,27 kHz escutado no Reino Unido

Canadian radio ham's 10 µW ERP 8.27 kHz signal heard in UK

SWL Paul Nicholson in Todmorden, UK successfully received an extremely
low frequency transmission on 8.27 kHz from Joe Craig, VO1NA, in
Newfoundland

The ARRL reports:

For Joe Craig, VO1NA, in Torbay, Newfoundland, things have been pretty
exciting lately on VLF (very low frequency). He’s among the early MF,
LF, and VLF experimenters in North America — active even before Canada
allocated Amateur Radio bands in that part of the spectrum.

He believes he accomplished a “first” for a Canadian radio amateur on
October 22, when his very VLF, very QRP signal on 8.27 kHz (that would
be the 36-kilometer band) was copied in the UK.

“After much effort on both sides of the pond, SWL Paul Nicholson in
Todmorden finally copied a three-letter message,” he told ARRL. “It’s
the lowest-frequency transatlantic message, made possible because of
Paul’s EbNaut coherent BPSK mode and DL4YHF's Spectrum Lab spectrum
analyzer.” Even more amazing: The power was 10 µW ERP.
Craig is permitted to run 10 mW by regulator ISED Canada (formerly
Industry Canada). The transmission path was more than 3,500 kilometers
(approximately 2,170 miles).
