Amateur Radio-developed software assisting in search for missing airliner

ARRL report that US Navy personnel helping to look for missing
Malaysia Air Flight MH370 are using the signal-processing and analysis
package Spectrum Laboratory by Wolf Buescher, DL4YHF, to analyze
recently detected 37.5 kHz 'pings' that may be from the missing
plane's 'black box'

Some Spectrum Laboratory screen shots as seen aboard the Australian
Defense Vessel Ocean Shield were shown on TV. The US Navy personnel
are guests aboard the Australian ship. VLF experimenter Warren
Ziegler, K2ORS, said the software is the same package Amateur Radio
experimenters used recently to detect transatlantic signals on 29 kHz.

“Wolf’s package is very first-rate software, and I know that there
have been other professional uses, but this was quite an interesting
one!” Ziegler said.

The software began as a simple DOS-based FFT program, but it is now a
specialized audio analyzer, filter, frequency converter, hum filter,
data logger and more, and it is available for download from DL4YHF’s
Amateur Radio Software site.
