Totally serious, since the only ways that I know that ham operators
can xmit are voice and codes like Morse.
http://en.wikipedia.org/wiki/Morse_code
Morse code is the only digital modulation mode designed to be
easily read by humans without a computer, making it appropriate
for sending automated digital data in voice channels.

Now that I've read http://en.wikipedia.org/wiki/Packet_radio I
(think I) understand it better.
The first amateur packet radio stations were constructed using
surplus Bell 202 1,200 bit/s modems
