Tobias,

A quick response to your testing.

1. End of signal wave shaping will be a little more difficult, but I'll see what can be done.

2. Each change in signal encoding/decoding necessarily not be backward compatible.? The result of using different different Viterbi polynomials and interleave depth.? No free lunch however, since increased interleave depth and more complex Viterbi means more demands on CPU performance.

3. Slow versus Fast CPU.? For anything other than an old P3 I recomment using Fast CPU setting.? Slow CPU setting tries to compensate by reducing the number of simultaneous path evaluations.

4. SNR evaluation is heuristic and the algorithms always have "factors" in the equations.? I'll do some additional testing with pure AWGN created with linsim.? Linsim is a PathSim replacement available for Win, Linux, and MacOS.? See

comptext and comptty allow one to measure the CER and BER associated with ASCII text and RTTY text files respectively.

5.? AFC has no meaning for Thor.? I will disable the button.

6.? I will increase the AFC low pass filter coefficient to a maximum of 500.

Vielen Dank fürs Testen. Die Ergebnisse sind sehr gut.
