Raduino: Disabled CAT in the Raduino main loop. Fixed some split freq setting via I2C. TeensyDSP: Added a Keyer. Works ok, but I have to disable ADC during transmit (or all of CW?) in order to keep the timing good... need to use interrupts and/or continuous ADC at some point. Added the MD CAT command, and fixed other CAT commands. Split seems to work, but don't do split when using the keyer! Halted the Raduino.
