WSCGen Description

This program was written to experiment with using the PC soundcard for producing various amateur radio modulation signals. Currently it generates a single tone, SSTV S1 and M1 test images, PSK31 BPSK and QPSK signals, and CW code signals. The carrier frequency for the PSK31 generator uses the value set for the sin wave generator and can be set in increments of 1 Hz from 300 to 3KHz. Additive Gaussian noise can be added to each signal. The noise is BW filtered through a 400-3400Hz. filter trying to simulate a typical receiver channel. The SNR ratio of zero dB is when the RMS value of the signal equals the RMS value of the bandwidth limited noise.
