Why can't I REALLY select USB mode?

Hi. I'm using WindowsSDR to control a 6600M which is unlocked for MARS operation. When selecting a frequency in the upper 6MHZ band, the radio will NOT operate USB. The selector/flag says USB but when looking at the actual passband, it is operating LSB. I could select AM, CW, LSB and DIGU, but when selecting USB, the passband does not change even though the software indicates in two places it is USB. I have not had this issues in any other band. Thanks for any help. 73

    I’m also MARS. I’ve experienced this only one time myself. Rare. But indeed strange. I would suggest both a PC and a radio reboot.

    Thanks John. I guess I should have mentioned that. I DID do a total reboot of both with no change. I just tried a second total reboot and it worked fine !! I guess it was just a "glitch in the matrix" during the first tries. I guess we can disregard this question and maybe just have this as a heads up for others who might encounter this. REBOOT a couple times.

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.
