ARC-182 T/R&G does not mointor guard 243MHz

[FoxTwo]

I have created a mission where there's broadcast chatter on the guard channel 243MHz. I tested it in several modules so far and it works fine in the F-18, F-16 and UH-1H.

 

It doesn't seem to work in the F-14. I turned on ground power, hopped into the RIO position and turned the ARC-182 V/UHF radio on. Set it to TR&G, manually set the channel to 264MHz. Can't hear anything. Setting the radio to G works, and manually switching to 243.00MHz works, but the guard monitor setting does not work.
