i am interested on getting the oceanic clearance on DLH411 that left , the 23/03/2013 from Kennedy
Do you mean the actual "oceanic clearance" or just hearing the flight while it was in oceanic airspace ?http://flightaware.com/live/flight/DLH411/history/20130323/2240Z/KJFK/EDDM
On this routing via DOVEY the flight would have received their oceanic clearance on the ground in JFK (via datalink).
If you listen to the JFK ARINC archive that InterpreDemon posted above (JFK-ARINC-Mar-24-2013-2330Z) at 21:40 you can't hear the aircraft (out of range) but you can hear the ARINC operater reading back DLH411's altitude (FL360), confirms CPDLC, time at DOVEY (2355Z), and their selcal code (KM-GR), their next position 46N60W, then gives them their HF assignment for the crossing (New York primary 5520 secondary 6577, then crossing 44'30N to Gander primary 5616 secondary 8891).
As far as I know there is no LiveATC feed that covers 5520, but there is one that covers 5616. http://archive-server.liveatc.net/hf/HF-Atlantic-NAT-B-Mar-24-2013-0130Z.mp3
If you listen to the above archive at 8:00 you can hear DLH411 check on with Gander on 5616, confirming CPDLC, confirming track "W", getting a selcal check, advised secondary Gander frequency now 3476, then told to contact Shanwick crossing 30W on primary 3016 secondary 2872.
As far as I know there is no LiveATC feed that covers 3016.
you CAN access HF archives if, instead of browsing the "misc" to "HF", you simply enter "HF" into the "Airport/ARTCC Code" box
I've always been able to access HF archives directly from the archive link as well.http://www.liveatc.net/archive.php
