    No. The 6600 must use 2.1.x versions or newer. I recommend 2.1.33 The radio will refuse to downgrade. Dave wo2x

    Dave is correct.  The minimum version of SmartSDR for the 6600/6400 is v2.1.  Earlier versions do not have a HAL (hardware abstraction layer) that supports the new 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.
