When SNR>90 dB is specified, simulated signal is noiseless. If Doppler spread is nonzero, then signal will have random peak amplitude. In this case normalize the signal so that peak amplitude=32767.

grid contest messages. These messages are now recognized as standard

when contest mode is selected and applicable (currently FT8 and MSK144
only).
