Can't get VARAC to tune a 6400

in Third-Party Software

I have VarAC 11.4.0 setup on a Windows 11 PC and connected to a local 6400.

  • When I tap on TEST in VarAC settings, the radio changes frequency, so CAT appears to work
  • When I tap on PTT ON in VarAC settings, MOX comes on on the radio, so PTT seems to work. However
  • When I tap TUNE in VARAC, MOX does not come on. Audio is being sent via DAX.

Any ideas? Images follow

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.
