[GreenKeys] QUES about coded transmission

[tony j. podrasky]

I think you were looking at the transmission from weather
stations - like WSY in Sayville, Long Island New York and
WBR70 in Miama Fla.

One of them used to be just outside the 20M amateur band
at 14.350MHz. Every once in a while they would break into
English text. 

I designed a SELCAL that was programmable and I would set it up
for key words like WEATher, REPOrt, HURRicane, TROPical,
STORm, etc so I could capture the readable forcasts.
