I wasn't able to participate in the test, but I've listened to both Bill's and Barry's audio clips of the morse code--transcription follows: WCXH WCXH WCHX MONTICELLO, MAINE WCXH WCXH WCXH (14 upward-sweep tones follow the code) Note the third code group is an erroneous transposition of the station callsign! The speed indeed is slow--one could write the dots and dashes down and then decipher them afterwards with a code table, even if one didn't know the code, at that slow speed. LF NDB's use similar slow code for that very reason--the pilot can copy the dots and dashes and look up the ident if he really wants to verify the signal on a particular frequency is the one he's expecting. The use of a comma (dah dah di di dah dah) following the city is not often heard. I used to copy the merchant marine press broadcasts sent to ships at sea--since the copy being broadcast was machine-generated, it used all the various morse code punctuation characters--parentheses, semicolons, etc. Most of those characters would only be heard on those press broadcasts and nowhere else.
