representative or reporter from that news agency from xinhua that is on the haixun, on this boat. that is where the information is coming from. i want to bring in david suicie. david, you have been watching this for four weeks. we have been hesitant to say this is a big find. we do not know. there is no confirmation. as you hear this, this is a pulse signal that was found off this ship at the frequency of 37.5 kilohertz, which is the standard beacon frequency, what is your first reaction? this is a pinger. i have been doing this for a lot of years. i can t think of anything else that could be. they said it is every second and 37.5. that is a pinger frequency and it is a pinger of pulse of every one second.
specific point. that may help. the frequency is right. 37.5. the circumstances are really questionable. what else transmits at that frequency? what else might it be? it doesn t really have to be at that frequency. the locator or whatever detection device they have can pick up other nearby frequencies. sometimes 100 kilohertz which would be side-scan sonar or other sonar can interfere and if they are not used to reading and analyzing the signal, one could take it the wrong way. mr. carr, unless the chinese had information that led them in this direction, this would truly have to represent finding the needle in the haystack. indeed it is. you have to be on top of it
these flight data and news recorders. the chinese news agency reporting today that the chineses have willel was able to pick up a pulse that matches the same frequency that is usually detected on these beacons on these flight data recorders and that frequency as you heard from aneesh patel which as you said was very distinctive. it is something that being not be detected from human ear, but instead you need to have special sonar and acoustic equipment and that chinese vessel claims it had that kind of equipment in which to detect that frequency, 37.5 kilohertz per second from somewhere in the southern indian ocean there. we ll have much more on this chinese news agency report and we ll try to reconnect with aneesh patel to give us a better explanation. you re looking at a flight data recorder and that beacon. that very important beacon with the battery life, the life expectancy of some 30 days and that would be this weekend. we ll be right back.
this regular 37.5 kilohertz cycle clicking, it s very distinct. and if, in fact, they got that, then there will be other assets that will be able to locate it quickly. one of the nuclear submarines from the united kingdom is there. they have extraordinary listening and hydro phonic capability. okay. you say this is a distinct sound. john, is it an exclusive sound to these black boxes? is there anything else out there under water that could be making a similar sound? it s designed to be unique. first and foremost, it s very regular. it clicks. about once a second. nothing else really does that. and the specific frequency is set to not be something that an ocean mammal or any ocean-going sounds could be. so it is unique. okay. and the next steps here are what? first and foremost, to get the assets there to get other listening devices nearby. also, to see what the floating debris that was sighted nearby.
and they would want to take credit for that, i assume, for their countrymen and people on board the plane. it doesn t surprise me that they would have something else, but it does surprise me they didn t coordinate with the task force because like i said, that could get you kicked off the task force in the united states. you would. you would be off. mary, we have important voice joining the conversation in a moment. speaking of sharing and protocol. i m read it. the australia defense force learned on saturday at 8:46 p.m. let s say six hours ago, about the chinese report that the haixun patrol ship picked up the pulse frequency of 37.5 kilohertz for the missing malaysia airline plane. the adf expects china to notify malaysia first and notify australia, quote, in a matter of
