hi Todd - As I understand it, the K3 when transmitting RTTY via CW paddles does not send "diddles" - rather, it stays in a constant state until you give it a character via the paddles and then it sends the character.
Some decoders and some decoders under some conditions do not respond well to this because the decoder gets out of sync - the start time of the second character is not an integral number of character periods from the first character. These decoders sync with the character cycle in an attempt to reduce errors. Most encoders send "diddles" - a non-printing character like LTRS sent over and over - to help the decoder maintain character sync when there is no printing character to send. A great explanation of this can be found here: http://www.aa5au.com/gettingstarted/rtty_diddles_technical.htm I probably have some detail of this wrong but I'm pretty sure the gist is correct. 73 jeff wk6i On Thu, Dec 19, 2013 at 9:23 AM, todd ruby <[email protected]> wrote: > I tried working ZS9MADIBA today and he kept coming back saying my > settings must be wrong because I was not printing correctly.
