COQUELET MK 2

Synchronous Simplex MFSK system based on the earlier Coquelet Mk1. Uses direct translation of a 5 unit ITA-2 character into a sequence of two tones out of a total of 8. Each tone lasts either 37½ msecs or 75 msecs therefore Baudrate is either 26.67 or 13.33 Baud.

The Idle or Standby condition is represented by tones 1 and 8 alternating, (i.e. the two outside tones) making it very easy to tune into when idling.
