The SL-30 data output from the Razor has a bug. The VOR CDI data is reverse sense. The localizer and glide slope seem to be OK.
I've made several support requests and have not received a response. I can provide data, if needed.
Regards,

Re: Razor SL-30 CDI bug
I'll add a selection for the output polarity in next release soon.
Sorry been focusing all my effort on the G4 which was super urgent - but that is now done and I can get back to the more "boring"

Any chance I can get a Razor firmware update soon?

Re: Razor SL-30 CDI bug
While waiting for a software fix I decided to correct the SL-30 output myself. I built a converter from an Arduino Nano Every that reads the SL-30 data from the Razor and reverses the sense of the VOR CDI. It passes all other messages unchanged, including Localizer CDI.
I flew it today and it seems to work. The EFIS CDI display is correct and I can couple the autopilot to the VOR.
