f194621695 Many improvements to ft2, including: 
- SNR displayed on decode line
 - Separate transmit() subroutine
 - Output sent to all_ft2.txt
 - Display Rx level (hit L to toggle On/Off)
 - Auto-sequencing  (hit A to toggle On/Off)

cf1fe6c3d6 More work on FT2. New frame format is 16sync + 128codeword. Data chunk is assumed to be 2.5s long. A rudimentary sync routine is implemented which finds the single strongest signal. 2019-01-12 13:28:10 -06:00
