Sukhoi and Terminal ELT frequency signals in Indonesia Unlike Catchers

Sukhoi Superjet 100 aircraft equipped with emergency equipment locator transmitter (ELT) which at times lights up when the plane hit a foreign object. However, the signal from the ELT that should be captured by the receiving terminal in Indonesia, Singapore, and Australia was not also detected the three terminals.
National SAR Agency head Vice Marshal Daryatmo suspect, Sukhoi ELT signal loss when the collision occurred because of differences between the ELT signal's frequency and the frequency of the receiver's Sukhoi's Indonesia.
"It's a tool that is designed not to ELT-detect on the satellite," said Daryatmo on Monday (5/14/2012), at Halim Perdanakusuma Airport, Jakarta.
He explained that the ELT frequency Sukhoi is at 121.5,203 Mhz. Meanwhile, the frequency of the signal which became the standard in Indonesia is 121.5,406 Mhz. "So, it's just remove the old system of signals, then we are humming. We'll get to (the frequency) that, along the same tools we have," said Daryatmo.
Meanwhile, Masrury, Head of Research Sub Committee on Air Transportation Accident NTSC, claimed to have seen ELT Sukhoi's rescue team found the crash site. "ELT in question, I have not seen, so I can not comment," he said.
ELT is a must-have tools of commercial aircraft. The device will automatically send a signal when the plane hit the water or hitting a hard object. However, an emergency signal from the ELT Sukhoi Sukhoi Superjet is emitted when 100 hit the cliffs of Mount Salak.
