K3 KY command and RTTY

[Tom, DL2RUM]

Hi,

I'm not quite sure if the following a bug under 3.30:
Mode is set to Data FSK D
When sending text to the TRX using the KY command, the text will be sent out and after that the signal is idling (didles) a while before the K3 switchs to RX. That's okay.
But when sending the next KY command during this idling time, the transmission changes to an unmodulated carrier, without didles. It takes few seconds before the next text will be send out.

Any suggestions?

Interesting. I can reproduce this using KComm by selecting the K3 DSP modems option, clicking Start sending and typing slowly. PSK D appears to have the same problem. The transmission doesn't change to a single tone, but there is a delay of a couple of seconds before the next character is sent. This is with the last beta version sent to registered beta testers.

I could send only one command for the text to send, but then there is no way to interrupt the transmission. It seems the ˆD don't clear the buffer and stops sending immediately.
In this way the KY command is useless for me in RTTY. My idea was to add direct FSK output in my Dx-ped logger.

You are right about this, too. I am sure it did used to work when I originally wrote the code for KComm to work with it. But I haven't used it much since I always have soundcard software anyway, so I don't know when it stopped working.

I'll look into this on the K3 end.

The problem still exists under 3.63
