It is also a possibility that dummy traffic is sent when there is nothing
"of value" to transmit.

This way of doing has several aims

- Preventing intercepters from easily finding when there is real traffic

- Misleading (and increase effort and thus operating costs) of opponent
  cryptanalysers

- Holding the frequency, detering anyone (other services, broadcasters
  pirates, ...) from using this frequency. "Nature abhors vacuum" and
  this is (or at least once was) true for the HF spectrum. For instance,
  by the time of Cold War, Radio Moscow International used to broadcast 
  its FF programme on up to 14 different frequencies at the same time,
  even in mid-afternoon (Who was listening to them besides retired
  and unemployed people ? New-born babies, maybe ?)

If we take the case of E03, how can we explain the transmission is
*always* 200 5FG long ? There must be a way to discriminate groups that
"carry a useful load", if any, from those that do not.

I am just wondering if having a transcript of these messages undergone a
suite of statistical tests compared to similar pseudo-random computer
generated message would receal something. Has anyone tried ?

(Yes, I know, computer pseudo random numbers generators are not the
absolute panacea, but it would nevertheless be instructive)
