The reliability of these transmitters was no accident. This transmitter flew throughout WW II and well beyond the war even out into the late 50s and even 60s and was used by many Air Force, Navy and civilian aircraft. It had a reputation for reliability and ease of use that was second to none in its category of radio. It flew in many aircraft ranging from heavy bombers down to multi seat fighter bombers and eventually into some of the larger single engine/single seat fighters like the P-47 and the P-38 Lightning. When you think of the Collins Radio Company during the WW II period, you naturally think of this family of transmitters – and rightfully so.ĭerived from the original commercial aircraft line of Collins Autotune transmitters of the 17D prewar family, this ruggedized and beautifully designed 100 watt HF transmitter was, and still is, the pride of Collins Radio. Probably – No, most certainly! – this is the ubiquitous Collins World War II transmitter. (See Chapter 3, Paragraph 9 of Order 8120.11 and Chapter 14, Paragraph 3 of Order JO 8020.16.ATC & AN/ART-13, JAN T-47/ART-13 TRANSMITTER Copyright 2013 CCA I suspect they also might not release this data, though, particularly while the investigation is still underway. I believe it is the policy of the NTSB to not release audio files, but you might have luck submitting a FOIA request to the FAA directly. You can rest assured that the FAA is compiling the audio from this flight and preparing transcripts which may be released to the NTSB. Los Angeles Center 124.200 was recorded, but I listened to an hour of audio and it seems that N801DT did not enter that controller's airspace. Nor are some of the other likely frequencies for their route:
Unfortunately the pilot was instructed to contact Nellis Approach Control on 135.100, and that frequency is not recorded at LiveATC. This bodes well for your goal to retrieve audio archives for their entire flight. The pilot requested flight following, meaning that even after they departed the Class Bravo airspace and were no longer required to communicate with ATC, they wanted to remain in communication and receive traffic advisories, etc.
#Atc radio archives code#
The pilot is instructed to enter a specific squawk code and is identified on radar. The file as played in-browser may have slightly different times.) (The time referenced is elapsed time on the downloaded file. You may hear their initial communications beginning at the 28:20 mark of the KLAS4-App-NE-May-08-2022-1700Z.mp3 file accessible from the LiveATC archives, that is, the ~30-minute audio file which begins at 1700 UTC on May 8th. They were required to establish communications with Las Vegas TRACON prior to entering this airspace. At their altitude, the pilot would not have been required to be in contact with ATC.Īs the aircraft climbed out of BVU and flew northbound, they entered the Las Vegas Class Bravo airspace. The frequency providing services in the immediate vicinity of the airport is 124.475, which is not recorded at LiveATC.
That frequency ( 122.700) is not recorded by LiveATC and likely wouldn't tell us much if it were.īVU is under the jurisdiction of Las Vegas TRACON. I was not able to find anything more than that.īVU does not have an airport traffic control tower instead, pilots self-announce on a common traffic advisory frequency. I have found one audio file which contains communications from N801DT near the beginning of the flight. The end of the data in the link is the last reported location of their flight, so that should help us get an idea of which towers they were in communication with and at approximately what time. I will link the ADSB data and perhaps some folks in this community would be able to suggest which towers they would be communicating with so I can better refine my search in the audio archives. Yes, there will be an investigation report in 6-12 months, but obviously we would be curious to gather what we can for now. I'm curious if they may have reported their situation to Center so we can help all of their friends (big aviation community around them) get some understanding and closure. It appears as though they had loss-of-power if you look at the flight data, and vectored to land on a nearby freeway.
Would it be ridiculous to ask if anybody perhaps would know where to look for potential ATC recordings? I have found archives such as, but I don't even know where to begin for which towers they hopefully communicated with before putting it into the dirt. Unfortunately this Sunday I had a friend and her husband who crashed and didn't make it.
