This example is a modem using DQPSK with LDPC codes to improve the performance of the HAM protocol PSK31. The passband signal can be passed both in and out of the soundcard. Both HF channel impairments and AWGN can be added. Text is encoded in varicode as it is done in PSK31. The default settings use the same bandwidth and net bit rate as PSK31.
