Attempted incorporation of W0EB interrupt-based keying code from Raduino I2C clone. Kept locking up during the setFrequency() and/or SetCarrierFreq() calls that occurred within startTx() when called from the ISR. Don't have time to work through understanding how to integrated the KD8CEC complex spaghetti codebase with the otherwise relatively straightforward ISR. So I think I will revert to the non-ISR version.

+#KC4UPR'S NOTE
+----------------------------------------------------------------------------
+This is a fork of the KD8CEC firmware that will be specific to my uBITX V5
+installation.  My intent is to remove unnecessary code, as well as make some
+GPIO changes based on my use of the Nextion LCD.  Specifically, I'd like to 
+eliminate the use of analog I/O for reading the CW keys, and possibly enable
+control of accessories such as filters using the extra GPIO pins that are
+now available.

- CW Keyer
- CW Key logic change with ron's code (ubitx_keyer.cpp)
- Ron's logic has been modified to work with the original uBITX by KD8CEC
-
- Original Comment ----------------------------------------------------------------------------
- * The CW keyer handles either a straight key or an iambic / paddle key.
- * They all use just one analog input line. This is how it works.
- * The analog line has the internal pull-up resistor enabled. 
- * When a straight key is connected, it shorts the pull-up resistor, analog input is 0 volts
- * When a paddle is connected, the dot and the dash are connected to the analog pin through
- * a 10K and a 2.2K resistors. These produce a 4v and a 2v input to the analog pins.
- * So, the readings are as follows :
- * 0v - straight key
- * 1-2.5 v - paddle dot
- * 2.5 to 4.5 v - paddle dash
- * 2.0 to 0.5 v - dot and dash pressed
- * 
- * The keyer is written to transparently handle all these cases
- * 
- * Generating CW
- * The CW is cleanly generated by unbalancing the front-end mixer
- * and putting the local oscillator directly at the CW transmit frequency.
- * The sidetone, generated by the Arduino is injected into the volume control
