Re: TX136/500 v1.07 OPERA and JASON modes added

As far as my test, the start bit shall be one bit as Patrick's program and Jose's opera_generator.

Re: TX136/500 v1.07 OPERA and JASON modes added

Hi Patrick, I feel a small difficulty to add a space in QRSS/DFCW/JASON message using beacon configulation mode.
