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. > Packet radio IS the layer 1/2, which clearly rules out Morse code. > In fact, IP is encapsulated into AX.25, which is layer 1/2 for packet > radio. > > But who said anything about IP?

The first amateur packet radio stations were constructed using surplus Bell 202 1,200 bit/s modems -- ----------------------------------------------------------------- Ron Johnson, Jr. Jefferson, LA USA "Have you ever thought about just turning off the TV, sitting down with your kids, and hitting them?"
