 After analyzing Loomis' papers, they concluded that "it is very difficult to give Loomis's notes the proper interpretation", and "even the most thoughtful consideration does not seem to reveal the facts that he had in mind".In addition, they found that his patent "specifications, in the light of our present-day knowledge, are so ambiguous that it is difficult to get their real meaning".Given the lack of information, they concluded it was unclear whether he had employed the high-frequency electrical currents later determined to be necessary to generate radio signals, on the other hand, "It cannot be said with certainty that he did not use such currents."
