CWTune CAT command

While I am waiting for my Aurora AU-510M to be delivered end of the year, I have been wading through the CAT commands in the available manuals. Kenwood has a very practical CAT command “CA01;” (or a button on the front panel ‘CWTune’) which immediately pulls a received CW signal to the set ‘pitch’ audio frequency. My hope ... maybe this will be included in one of the future SmartSDR versions.

In preparation for the Aurora, I have written a Python program that analyzes the audio spectrum and pulls the CW signal to the pitch audio peak via CAT “FA...;”.

    I doubt that Flex will expand their CAT commands. Instead, take a look at the Flex API. It allows complete control of the radio. I have sample code on GitHub - search for KD0RC. You may also want to look onto Node Red. Dave, WO2X has done some amazing things with it and Flex radios.

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.
