+    Funtronics FK-10 Programming Notes (Contributed by Disneysw 2016-12-10)
+
+      Programming the unit is accomplished by selecting "Mega2560" as the target processor and uploading to the rear USB port with the front
+      switch set to the Arduino position
+
+      Note: in order to get the FK-10 USB Host port working correctly you will need to patch the file "UsbCore.h" in the USB_Host_Shield library.
+      At the time of writing it is line 41 that needs modified to change "P10" to "P53" i.e. from
+
+           #else
+             typedef MAX3421e<P10, P9> MAX3421E; // Official Arduinos (UNO, Duemilanove, Mega, 2560, Leonardo, Due etc.) or Teensy 2.0 and 3.0
+           #endif
+
+      to:
+
+           #else
+             typedef MAX3421e<P53, P9> MAX3421E; // Official Arduinos (UNO, Duemilanove, Mega, 2560, Leonardo, Due etc.) or Teensy 2.0 and 3.0

+    Funtronics FK-11 Programming Notes
+
+      Programming the unit is accomplished by selecting "Arduino Mega 2560" as the target processor and uploading to the rear USB port with the
+      front switch set to the Arduino position.
+
+      Note: in order to get the FK-11 display working correctly you will need to:
+      - Install FaBo_212_LCD_PCF8574 library
+      - Set the slave address to 0x27 in FaBo_212_LCD_PCF8574/src/FaBoLCD_PCF8574.h
+        #define PCF8574_SLAVE_ADDRESS 0x27
+      
+      Note: in order to get the FK-11 USB Host port working correctly you will need to:
+      - Uncomment three lines in in file: k3ng_keyer.ino below 'note_usb_uncomment_lines'.
+      - Add line to file k3ng_cw_keyer/libraries/USB_Host_Shield/settings.h, below 'Manual board activation':
