 +objective:
 +
 +  *     to read frequency and mode from transceiver and manage frequency set with computer (CAT)
 +  *     ​transmit command from computer (PTT)
 +  *     ​transmit from leg pedal (PTT-IN)
 +  *     ​transmit command to external circuit, such as Power Amplifier (PTT-OUT)
 +  *     key from computer (CW/KEY)
 +  *     ​paddle support
 +  *     ​modulate radioteletype signal (FSK)
 +  *     ​phantom power for microphones
 +  *     ​connect microphone cirtcuit only when PTT-IN is pressed
 +  *     all operating system supported (original FTDI chip)
 +  *     SMD components 1206 (big enought to solder by hand)
