[GreenKeys] Model 19 on Ebay

[epvgk at limpoc.com]

Finally got the M19 on the air today, using a demod board plus an optical interface
to key the radio. My IC7000 has a "real" fsk mode where you feed it a DC voltage to
tell it whether to send the mark or space tone, and another DC voltage to tell it
whether to transmit or receive, and it does all the FSK itself. So with the interface
box connecting the loop to the radio it's pretty easy to get on the air using just
a transmit/receive switch.  I even made a set of "macros" using the punch, so i could 
send "CQ" and the rest from paper tape, which was fun.  Nothing new for folks here
but it was pretty neat having no computer involved at all...
