[CW] ARRL bad CW Practice

    BTW, this may have answered a puzzle on my part. When I 
copied press transmissions from RCA and MacKay long ago I found a 
couple of small differences in practice: RCA used quotation marks 
before and after quoted text while MacKay sent two apostrophes. 
In this ITU document it states that the repeated apostrophes may 
be used where there is an automatic code translator operating. I 
suspect this may explain the use of this practice by MacKay 
although I have no specific information. I don't remember the 
other slight differences except that RCA used all conventional 
signals.
    For those who don't remember the RCA stations were WCC and 
KPH and MacKay stations were WSL and KFS.   Both stations sent 
United Press news for subscribing ships every day for about two 
hours. The signals originated on paper tape.
    I also heard press sent from WNU in New Orleans (Tropical 
Radio Telegraph Co) but it was sent by hand and was interspersed 
with traffic. There may have been other press sent by U.S. 
stations but I never heard any.
