Keying problem

Since I have upgraded my Flex 6400 to 3.2.37, I am having intermittent keying problems. The dots and dashes are not uniform. Occasionally, the keying is perfect, and yesterday I operated the CQ CW WPX using N1MM+ to key the transmitter with no difficulties. Today the keying is uneven, so much so, that I am unable to have a QSO. Normally I run SliceMaster and either a Skimmer or WSJT, but I have tried this running no other programs, and keying is unusable.

Where should I begin to troubleshoot?

    Have you tried setting TX delay in SmartSDR to 20 ms?

    Are you using an amp? If so, which one?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
