PORTABLE KEYBOARD INTERFACE FOR CW AND DATA MODES TAKE YOUR KEYBOARD TO THE
FIELD FOR PUBLIC SERVICE OPERATING OR OTHER ACTIVITIES.  MIKE MUSSLER, AI8Z
MY WIFE, JAN, N8SEW, AND I WANTED A KEYBOARD TO INPUT PSK AND RTTY INTO OUR
ELECRAFT KX2 RADIO, WHICH NORMALLY USES A MORSE PADDLE FOR CHARACTER ENTRY.
THE PORTABLE KEYBOARD INTERFACE DESCRIBED HERE TRANSLATES STANDARD PS2 OR
USB COMPUTER KEYBOARD CHARACTER ENTRIES TO MORSE KEYER PADDLE STROKES AND
IS SUITABLE FOR THOSE WHO ARE NOT ADEPT WITH, OR DONT WANT TO USE, A KEYER
PADDLE.  IT CAN BE USED WITH ELECRAFT KX2, KX3, AND K3 RADIOS TO TRANSMIT
PSK OR RTTY CHARACTERS IN THE DATA MODE, OR TO TRANSMIT CW IN THE CW MODE.
FIGURE 1 SHOWS THE PORTABLE KEYBOARD INTERFACE CONNECTED TO THE ELECRAFT
KX2, A PORTABLE KEY BOARD, AND A BATTERY.  ARDUINO MICROCONTROLLER SOLUTION
