Re: using the BITX on RTTY

A 45 baud FSK RTTY signal changes frequency each 22mS.  The shift for RTTY is 170Hz. From my limited experience (not consulting the datasheet) I expect the si5351 would handle this easily.   The trick would be getting the timing of the changes right.   A software timer such as the Arduino delay()  may not work as it is pretty inaccurate with small arguments.   A hardware timer that generates interrupts should do the trick.  It would be easy to try.
