I tried to simultaneously received APRS_9600bps signal by the software
MixW(3.1.1) and Soundmodem_9k6(0.10b), and I compared the decode rate.
Date: 14 Jun 2013, 22:51-23:06UTC
Frequency: 144.640MHz FM, 9600bps GMSK
DCD threshold: 5
Results: Soundmodem_9k6 ... 16
MixW ............. 49
It was the result of MixW wins overwhelmingly on the decoding experiment.
I think that there is a point of setting unadjusted in Soundmodem_9k6.
In addition, I can see the word "Mt.AKAGI" in the image, so I could hear
the signal from Mt.Akagi in Gunma away 130km from Yokohama.
