What Tony has done is quite helpful to many of us and I printed out his message as a reference. For some time I developed a chart of many of the parameters of the different sound card modes to get some idea of what modulation they are using, baud rates, throughput, ITU Emission Description (if

I believe that both have a space under the sun. The charm of the simulator tests is _repeatability_, even when the results on the air might be different.On the air, you cannot have repeatability, so, the results, even when real, are harder to correlate. Yesterday I attmoted to get some real

Rick, Has anyone compared Domino EX with the top modes that get through the worst conditions and, if so, what have you found? I've compared a variety of sound card modes for sensitivity and robustness using an HF path simulator (see below). I first tested each mode for sensitivity by finding

: KV9U - Mode Sensitivity / Robustness Hi Tony and it is good to see your posting to the group. I for one would like to try different modes and compare them under real conditions. There can be too many variables. I understand it is impossible to do it exactly but how about this scenario: We
