Ham Radio Automatic CW IDer ATtiny / Arduino Based

The Experiment: ATtiny/Arduino Based (Ham Radio) Automatic CW IDer. Build a (Ham) Automatic CW IDer around an Atmel ATtiny85 micro-controller which will automatically Identify the station  every 10 minutes. Features: Automatic CW Keyer, ID Reminder LED, PTT LED, PTT Active Input, Audio output level control and power by the radio.

The challenge, the ATtiny85 only has 8-pins, 8KB ISP flash memory and pin1-4-8 are dedicated to Reset-GND-VCC. So the first thing to do, assign the available pins.

Notes:

IC756 PROIII Accessory one(1) wiring
Pin2 = GND
Pin3 = PTT
Pin4 = Mic
Pin7 = 13.8v DC

Note:
Change 82K resistor for desired cw audio level
Remove jumper to manually Start ID timer without TX

Button functions:
SW1 = Send ID                 (when pressed sends CW station identification)
SW2 = Amp Tuning Aid  (when pressed sends tuning pulse)
SW3 = IDer On/Off         (when pressed turn ID audio On/Off, confirms On or Off in CW)
SW4 = FAN On/Off         (when pressed turns FAN On/Off, confirms On or Off in CW)
SW5 = PTT                        (when pressed turns Transmit On)
