早くも、New soundmodem が開発された。Tnx.>UZ7HO

There are a few changes:
1. "RX corr PPM" value to "55000" (it adjusted the internal oscillator
   for non-standard baudrate).
2. Changed the "UseStandardTones" to "0" this will keep the non-standard
   tone frequency "1800" hz (1200 and 2400 tones).
3. Added 1 additional pair of demodulators for better reception.
