If you transmit and thereby interfere with stations already using the 
frequency, then yes, the frequency is "busy".

In a nutshell, I am saying that automatic or semi-automatic stations 
should be capable of determining frequency use before transmitting. 
Whether you can decode it or not is irrelevant.

If you were operating phone and heard a language you could not 
understand, would the frequency be "busy", or do you need to decode it first?
