Version 1.029-2Captured Experimentation and Merged with FFT_Widget
refactor
V 1.029-3: More AGC changes
Version 1.029-4: Hopefully final AGC changes for a long time
V 1.039: Merger Waterfall display with AGC code
1) Few minor tweaks to the waterfall
2) Reduced Titles on SSB and CW screens to null (couldn't figure a
simply way to eliminate the code that generates the titles.
3) Added the AGC Mode, AF, RF, and RSL labels to the SSB and CW screens.
V 1.031: Revised DAC gains for transmit modes to acheive 1 volt p-p
V 1.032: 1)Extended range of HP & LO to -6 db
2)Removed AGC_Threshold2 / Replaced with RSL_Cal
Revised keyboard interface to support "HotKeys".  Currently, only F10
and Alt-F10 have been implemented.  Both of these toggle between Rx and
Tx. Ctrl and/or Alt can be used with all text characters or Function
Keys to call functions as desired.
V1.029-2: CW Initial implementation using interrupts.

- Added a timer interrupt to sample the input key.
- Improved CW waveform generation to be scalable.

Still needing:
- change to rx/tx mode automatically
- improve sampling timing of the input-keying.
V1.034: CW key sampling now done at higher frequency.

- CW still has a significant (~150ms) lag between key-down and 
  audible tone generation/transmission.
Updated keyboard interface.  Added HotKey capability.  Corrected errors
in keyboard decoding tables.

V1.035: Removed "AF offset" text, and line from waterfall, in SSB mode.
V 1.036: Removed Function Key F10 from macro list in Text Edit Menu.
Bug Fix--lower case y was not processed correctly
