1. [RTTY] Article by Brian Beezley, K6STI (score: 1): Author: aa6ty@att.net (Kok Chen); Date: Sat, 01 Sep 2001 09:53:04 -0700; Does someone know what the baud rate of RTTY 23 is? I think most people are saying that the shift is 23 Hz. I would not classify what we use on 45 baud Baudot RTTY to be narrow shift. It has a ratio; /archives//html/RTTY/2001-09/msg00029.html (7,260 bytes)
2. [RTTY] RTTY 23 (score: 1): Author: aa6ty@att.net (Kok Chen); Date: Sat, 01 Sep 2001 12:19:27 -0700; Confirmed that RTTY 23 is 45 baud FSK. I set the KAM Plus's modem to 2198 Hz Mark and 2222 Hz space and just copied KK5OQ at 21,085.82 KHz. My rig's dial is set to 170 Hz shift Mark, so you have to m; /archives//html/RTTY/2001-09/msg00031.html (6,898 bytes)

[RTTY] Article by Brian Beezley, K6STI (score: 1): Author: aa6ty@att.net (Kok Chen); Date: Sat, 01 Sep 2001 12:44:32 -0700; I just posted the computed spectrum (again, averaged over the equivalent of 45 minutes of real time) of 22.725 Hz shift RTTY (I suspect they may be using a shift that is synchronous to the baud rate; /archives//html/RTTY/2001-09/msg00032.html (7,748 bytes)
4. [RTTY] Article by Brian Beezley, K6STI (score: 1): Author: aa6ty@att.net (Kok Chen); Date: Sat, 01 Sep 2001 12:48:49 -0700; Sorry, I forgot to mention that the tick marks of the horizontal scale are 10 Hz apart. The "11 Hz" label is just the approximate positions of the Mark and Space frequencies. Sorry if this caused con; /archives//html/RTTY/2001-09/msg00033.html (6,953 bytes)
5. [RTTY] RTTY 23 (score: 1): Author: aa6ty@att.net (Kok Chen); Date: Sat, 01 Sep 2001 16:24:27 -0700; Surprisingly, the KAM Plus can copy RTTY 23 very well, using their "modem" mode and setting the difference between the Mark and Space frequencies to about 23 Hz. I copied MM0BQI/P on 20m with S2 on t; /archives//html/RTTY/2001-09/msg00039.html (8,076 bytes)
