Cancel CW transmission

Unread post by G0TPH » Sun 21. Oct 2012, 06:33

Hello,
I'm using RUMped 3.2 with a KX3 and I'm using the "TRX Built In" feature to get the KX3 to generate CW. Is there a way to cancel a transmission in progress, for example when I have pressed the wrong key or if I find I am doubling?

To cancel a transmission hit the Escape key. The K3 "KY" command will be used for generating CW. When pressing Escape, the the @ character (.--.-.) will be sent to the TRX. You have to change one menu to allow that.

From the "Programmers Reference":
@ In CW mode, this character normally terminates any CW message (via KY or manual send),
emulating the K2. However, tapping 2 in CONFIG:CW WGHT changes ‘@’ to a prosign:
the ‘at’ sign as used in e-mail addresses. This is the newest Morse Code character;
it can be remembered as the prosign ‘AC’ (as in “the At Character”).
I don't have a KX3 available, so your help is appreciated. As far as I remember, this option was not available in the first KX3 firmware. Please check! Then I have to use another way to cancel the transmission.

Please report.

Hello Tom,

Thank you for the feedback. My KX3 does not respond to tapping 2 in the CW WGHT menu so I guess this has not been implemented yet by Elecraft.

I am currently on version uC 1.12 and DSP 00.94 of the KX3 firmware.

This isn't quite the latest version - a new one has been made but the release notes don't indicate that the @ = STOP has been changed in any way so I guess it has not been implemented.

I will be loading this up and trying it in the next couple of days and I will report back either way. I have also sent Elecraft an email to enquire about this and I will let you know what they say.

Thanks for the info Alan. I will change the code also and use another command to cancel the transmission. When I started to code the K3 CW generation, the KY @; command was the only way to abort. But now we have other commands available and I guess most users will not still have a 2 years old firmware version active.
Stay tuned.

Hello Tom,

Wayne from Elecraft has just responded to say that it is not implemented yet, but it has now been added to his to-do list.

It is very kind of you to offer to update RUMped for this issue but I don't want to put you out for such a small problem. I can easily wait for the Elecraft update if that is OK with you.
