Thankyou RonMont for the reply. For whatever reason, it started working for me as of a couple of days ago.(Another issue that I had has fixed itself too). I'm not actually sure what has (presumably) changed, other than some updates that have downloaded for X-Plane. Either way, good news.

Thankyou Pils for the reply, and apologies for my delayed response (life/work....etc). It has started to work now, without me having changed anything, but it's good to know about the knob position. I did have another issue (for the Speed Call Out Mod), and that has 'fixed' itself too. There have been a few X-Plane updates that have downloaded, so I wonder if they fixed some other underlying issues in my build.

I'm new to both X-Plane and the Challenger and hence on a steep learning curve, but I thought that by pressing the respective illuminated VHF 1 or VHF 2 buttons on the Audio Panel they would 'mute' the respective COM 1/2 frequency(?) When I turn them, the volume goes up and down OK, but when pressing them so that the light goes out, I can still hear for example, the ATIS. (I've got both the LHS and RHS Audio Panels 'in-sync' with each other). Have I misunderstood their operation, or need to do something else too? Thankyou.

I wondered, does this work with Challenger 650 v1.8 and FlyWithLua NG+ (Next Generation Plus) for X-Plane 12 version 2.8.12? I've copied the files (v0.105) into the below directory, then started Xplane12 etc, but didn't hear any of the callouts - I haven't changed any settings in the script. \Resources\plugins\FlyWithLua\Scripts I had my takeoff speeds set via the FMS (shown OK on the PFD), and LUA seemed to be working as I could call up my Simbrief OFP list OK. (I don't have access to the PC at the moment to grab the LOG.txt, but can do in the next day or two if it would help). Thanks.

On the Autopilot Panel, there is a button labelled 'XFR'. I believe that will possibly help.
