Patrick, Just checked the peak amplitude of the RSID / Call ID clips and they are both within 0.2db of each other. These are the audio files I used to determine the 100% throughput SNR for each mode using PathSim. I am sending you the files so you can test them at your leisure. The RSID (Mode ID) and the CALL ID are repeated 8 times on each clip.
I repeated the test several times this evening and I still come up with the 6db difference between the two for 100% throughput. I should mention that I'm not using the Multipsk S/N indicator to measure the signal-to-noise; I'm using the SNR figures indicated by the path simulator. Tony -K2MO
