Rogers operated the only Canadian (and only spark-gap) station to successfully compete in the first amateur trans-Atlantic radio competition.
Rogers was not the only successful spark-gap station in the 1921 transatlantic amateur tests. Contemporary and ARRL historical records show that other spark-gap stations were also heard in Scotland.
Full reasoning
The article overstates Rogers's uniqueness in the 1921 transatlantic amateur-radio tests.
Edward S. Rogers's station 3BP does appear to have been the only Canadian station heard in Scotland, but it was not the only spark-gap station to succeed.
Evidence:
- ARRL's historical summary of the 1921 tests says that "more than two dozen stations were heard" during the test period and that "Some utilized spark-gap transmitters, others employed vacuum-tube CW transmitters." That directly contradicts the claim that Rogers's was the only successful spark-gap station.
- ARRL also published a bulletin about amateur operator Arnold R. Brilhart (2DN) stating that "The spark signal from 2DN was heard ... in Scotland" during the December 1921 tests. That is a specific example of another successful spark-gap station.
So the accurate version would be that Rogers's 3BP was the only Canadian station heard, but not the only spark-gap station to succeed in the competition.
