You are discussing about the lack off emergency call.
Was there any problem with TX?
Departure at GIG was covered by MEL.
BEA interim report:
1.6.4 Condition of the aircraft before departure
On arrival of the Paris-Rio de Janeiro flight the day before the accident, the Captain reported a problem at the level of the VHF1 selection key on RMP1. The aircraft has three RMPs: RMP1 on the left-hand side, RMP2 on the right-hand side and RMP3 on the overhead panel. The ground engineer had switched round RMP1 and RMP3 to allow the aircraft to leave, in compliance with the regulations (departure covered by a MEL). The departure covered by this MEL item did not have any operational consequences.

Were the CDR/FDR removed from 459 and data dumped?
If not, what a miraculous blunder.
IMO, the data recorders arn't "twelve hours long play models"
So, i supose that only the last 40 minutes were available when AF459 landed.
