#2 FM/HF Radio?

[Holton181]

So, I haven't found any information regarding mode "4" (#2 FM/HF) on the Signal Distribution Panel.

Have searched the forums and manuals, but very little information.

 

Anyone can shed some light on this?

What's it for?

How to use it?

Is it implemented at all?

I think it's not fitted in the DCS Huey and thus without function.

 

I'm not quite sure if that's the proper way to use it, but a while ago I've seen a German army UH-1D which simply had a second AN/ARC-131 FM radio fitted.

Thanks, I suspected something like that.

But since the manual doesn't really mention it, not even something like [Not implemented] like they usually do, I thought I would ask her.
