I’ll wait and see once I have my outline layed out before I decide on that. There is a lot of other things I want to cover in that paper.
In the mean time I’ll wait to see what you have on MacArthur. I’ll be interested to read it.
As an FYI, I did speak with my friend about the ability of an analyst to recognize unique characteristics of an individual machine transmission. He indicated that in theory, it should be possible but owing to the tight tolerances of the machine, an oscilloscope would have been required to display the waveform. The combination of aural and visual patterns would over time become recognizable to a skilled analyst, at least in determining the type of machine in use.
Within a machine type, differences could be determined but drawing specific conclusions would be difficult as variables such as machine maintenance would affect the nature of a transmission. That an analyst detected different transmission characteristics from transmission to the next might only mean the unit had been serviced, etc.
He also indicated that by just listening to manually transmitted morse signals, a skilled listener could determine the type power supply being used which would aid in IFF.

Don't expect a lot of info, I always try to address specific criticisms rather than just providing a large data dump. In this case, I will address some of the criticism's you and other posters have offered up against MacArthur. I was trying to give GreenLantern a chance to respond to some of my questions but so far, he hasn't.
