Using the ATU (Auto tuner)

in FLEX-6000 Signature Series

Hello my Flex 6400 has the built in auto tuner. Is there a PDF (Manual) on how to use the auto tuner? On my other radios I set my power to 25 w and put the radio in AM and tune up. I not sure how this works with the Flex 6400. One other question on this Flex control panel I notice I am set for "IOS Default profile" I know there is a pull down windows to choose others. Most of the time I run my Flex with the provided mic (Not the MOX with the PC and Logitech headset) And I listen through the third party powered speakers I have plugged into the radio.


Thank you.

    It is in section 28 of the SmartSDR Software User Guide V3.1.7, pages 98 through 100.

    The Flex has an independent method for tuning. Set the desired tune power and click the tune button. No need to change the main power setting or to change modes. Tune gives just a CW carrier at the displayed frequency.

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.
