Dear all,
just a short notice that the shown S/N values are those delivered by the JT9 decoder, not taking the audio conversion into account.
This means that the real S/N values are about 3dB lower (more negative) that shown for JT9-2 and 7dB for JT9-5.
I did some test this afternoon that comfirms this: for JT9(-1) and JT9-2 signal of the same amplitude and added to the same noise the shown S/N values for the JT9-2 signal were in average 2.7dB higher that for the JT9(-1) signal.
Although the S/N values are "just numbers", what really matters is if the signal decodes or not, I will correct this in the next release.
