RTTY Software Comparsions
In this test I have used the same file for each run through path sim with same levels with AFC turned off when I could , I retuned on each run through the simulator to help ensure I was on frequency through the whole test. I did three batches a run per software in uppercase set of letters to get a better average incase of any human errors or errors from the hardware itself. I also ran about 3 lines of letters through the simulator in one batch to help ensure that all letters seen different variables on the fades.
.
In all test there is
43 spaces/characters in one line
total 129 spaces/characters per section

I used a mid latitude settings with moderate fading situation with -6db SNR setting. The numbers you seen below is the amount of errors that happened in a batch. Errors come from letters not decoding correctly and/or spaces not decoding correctly
