The tick that started this thread is at a one second interval......

These scrambled (?) messages occur quite infrequently (perhaps 2-3 times
a day) and it is always in incoming message. The dispatcher usually
(but not always!) responds in plain talk.

About half the time, from the context of the dispatcher's message, I can
identify which field radio the scrambled (?) speech is coming from.
And, in those cases I will have heard the same radio in clear speech and
will hear it later on also.
