No TNC or cables; Cut & Paste
Slide 9 of 16
This is the single most important slide of this entire presentation. To send: radio and computer. To receive: radio and computer with mic. Simple, reliable, and redundant -- the essence of ham radio emergency communications.
Cut and paste (with computer commands "control C" and "control V") is also important -- portions of the text are copied to and from the message software with no additional keystrokes that might generate errors.
