[QCWA] landline morse question

[Joseph Fenn]

Well no we usually used  "BK" to stop the sender.   Many carryovers
were still used from RR telegraphy suce as  di dah dah  di di.
was one of them which means "wo"  or "who" whats your 2 letter 
sine.  "rj" was another carry over from continentl morse still
used in the 40's and 50's. It meant "wait am changing operators".
or "relief opr takeing over".  There were several othe carryovers
but at 87 I've forgotten some of them
