Bug report - incorrect modulation on VHF Radio

[sokunj]

Hi, yesterday I tried to dial in the frequency 140.5 AM and noticed it still showing as FM. although this is an AM band.  For example 133.0 shows correctly as AM..

Looks like a bug to me..

That is actually correct as is, based on publicly available information on the ARC-210 radio.

Unfortunately the radio is completely undocumented in the DCS A-10C II manual, however there is an excellent guide from Stuka and the 476 vFG that you can find here:

Of note, in the frequency range from 136.000 MHz to 155.975 MHz, the ARC-210 defaults to frequency modulation but allows for a manual switch to amplitude modulation, while the lower frequencies from 108 MHz to 135.975 MHz default to amplitude modulation.

You can toggle the modulation with the AM/FM switch on the ARC-210 control head, you can set it in the preset tab in the Mission Editor, and you can toggle it in the COMM -> ARC-210 PRESETS MFCD page.

Edit: Oh, and welcome to the forum!

Thank you,  I'll check it out tomorrow. 

Didn't know you can change AM/FM manually. Didn't find a button for that.

OMG.. as soon as I opened up this Manual I emediately saw that button ! 

Of course I started the sim right up and checked it.  It's located right near the seat wall,  in a way you just can't see it with Track IR.

Thanks Again for your complete answer.

Yeah, it's pretty well hidden unless you know exactly where to look for it.
