small bugfix

• renamed "CLARIFIER" to "Passband Tuning (PBT)" as this seems a more appropriate name for this function
• improved the code so that the si5351 does not keep receiving tuning updates once the frequency has reached the upper or lower limit

Added BFO calibration parameters for CWL and CWU

v2.03

• Added BFO calibration parameters for CWL and CWU to optimize the performance in CW mode
• Revised and improved the calibration procedures (tks Michael, VE3WMB)
• Corrected a bug that in certain scenarios mode switching did not function correctly
• Updated the instructions for the CW-CARRIER mod: Advise to use a 4.7K resistor instead of 10K in order to ensure full output power in CW mode
• Added capability (see line 31) to display the user's callsign on the second line of the LCD
• Added capability (see line 32) to adjust the delay time for 'fast tuning' (when the tuning pot is at either end of the range)

bug correction

• Fixed another bug in the calibration procedure
• Slightly changed the initial BFO frequencies to 11998800 Hz (LSB) and 11996600 Hz (USB)

bug correction

Fixed a bug that the VFO setting (high/low side of IF) didn't return to the original state after executing the calibration procedure
