I was wondering how the popular RTTY programs compare to each other in terms of decoding accuracy. To my surprise, a search on the Internet proved that such a comparison had never been performed, and

Hi Walter, The new RTTY SkimServer can process larger band segments than your software, but it works only with the wideband, multiband radios, such as QS1R and Hermes. It does not work with ordinary

Hi Tim, You have done an interesting experiment with your Bayesian callsign correlator. I think your experiment failed only because your system missed one important element, a Bayesian squelch. I hop

Hi John, Go ahead and use GRITTY with your 1500-Hz filter. You will see more garbage on the screen when there is no signal, but decoding accuracy will not be significantly degraded. 73 Alex VE3NEA 73

Hi Salvo, Currently GRITTY does not save decoded text to a file. However, it has a TCP-based interface that other programs can use to receive decoded characters, call stack updates, mouse clicks, etc
