Re: [IRCA] WCXH-780 DX Test

["Steve Ratzlaff" <steveratz@xxxxxxxx>]

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.
