6400 not keying Expert Linear

This is strange:

My 6400 has a Dan Tassel interface cable to the Expert Linear 1.5K - FA as does my Icom. The Icom is keying the radio no problem and amp is working. But on the Flex, it is not keying the amp so there is no functioning of the amp. I have looked at the menus but nothing jumps out at me. Any help?

    Hi Chris,

    Thanks. That was not actually it, believe it or not! The TX profile did not have the band checked off. As soon as I checked it off, voila! All is good! Lesson learned!

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.
