A Chinese ship on Saturday detected a pulse signal with a frequency of 37.5 kHz in the southern Indian Ocean, according to state news agency Xinhua.

Thus far, there is no evidence that the signal is linked to MH370. Nevertheless, the pulse is said to have the same frequency of the black boxes containing flight data from the missing jet.

“That is the standard beacon frequency,” said Anish Patel, president of pinger manufacturer Dukane Seacom, CNN reported.

“They’re identical,” he added.

According to the Associated Press, the Chinese report said the black box detector picked up the signal at around 25 degrees latitude and 101 degrees east longitude.

Crews from over two dozen countries have been searching for the Malaysia Airlines jet since it went missing about one month ago.

Late last month, Malaysia’s prime minister announced that an analysis concluded the aircraft had crashed into the Indian Ocean.
