That will let through the third harmonic of the keying sidebands (the 300/2; /archives//html/RTTY/2011-06/msg00025.html (7,658 bytes)

It would be great if that restriction could be removed but it doesn't appear that will happen. No, the 110 baud and above tes; /archives//html/RTTY/2011-06/msg00036.html (11,660 bytes)
