1. [RTTY] Jitter (score: 1): Author: Hank Garretson <w6sx@arrl.net>; Date: Mon, 26 Feb 2018 12:41:57 -0800; I understand that MMTTY FSK and Windows results in transmit jitter. I use MMTTY K3 FSK. 2Tone tells me I have jitter. I understand that my jitter reduces copy-ability (somewhat) for stations I'm work; /archives//html/RTTY/2018-02/msg00163.html (6,442 bytes)

Re: [RTTY] Jitter (score: 1): Author: David G3YYD via RTTY <rtty@contesting.com>; Date: Mon, 26 Feb 2018 16:04:15 -0500; Hank The TX bandwidth for 45.45 baud FSK is dependent on the radio rather than the system used for keying within reason. Obviously if the keyer is producing lots of short transients then it will wide; /archives//html/RTTY/2018-02/msg00164.html (8,368 bytes)

Fortunately, you use the K3 which is the rare (only?) one that filters the FSK signal. Ed I understand that MMTTY FSK; /archives//html/RTTY/2018-02/msg00165.html (7,920 bytes)

But it will sound "noisy" to ears that are used to clean RTTY. It is for a different reason that you want jitter to be low. You; /archives//html/RTTY/2018-02/msg00179.html (9,051 bytes)
