Made my military service in the Signal Corps as a telegraphist many moons ago. I've tried to decipher your message, but as the dots and dashes are quite irregular (as are indeed most spaces in between the dots and dashes), it's very much open to interpretation and I haven't been able to make anything conclusive out of it. My best guess is:
CN ESR N CN IEAN N ESE CN N IIII N EHE
which of course is absolute gibberish! But then again - I might be out of practice.
