Transmit interlock on 60 meters

I have been using my 6500 on 60 meters for years. All of a sudden, I get a message that transmit interlock is preventing me from transmitting. This has never happened before. I have the newest software. Perhaps this is another bug in the new, untested version! Any ideas out there?

    Thanks so much for that. That's exactly what happened! I had the transmit bandwidth set to 3KC from another band. Thanks so much. It now is working fine. Totally forgot about the bandwidth limits on 60 meters! Been a ham since 1960 and learning something every day! Thanks again.

    Hi Richard, what do you have your TX Filter Low Cut and High Cut values set to? If they are too wide, TX will be inhibited.

    I'm glad that was it!

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.
