Hi all;

(Spec: FSX-SP2, XP-SP3, C130X 1.3)

When I start a flight with the C-130 everything works ok. Then, after about 15 to 20 mins, the VHF equpment (NAV, COM, ADF) and AP stops working.

- The COM is on (current freq show in display) but I can't contact ATC.
- Not possible to change frequency on the NAV's or ADF.
- AP dead, can't even use power button.

When i click buttons in the panels (VHF/AP) the sound works but no reaction on the instruments.

I start a flight without a flightplan, take off, get to a decent height and then just fly straight ahead for about 15 to 20 minutes before the equipment fails. The first 10 mins of the flight everything (NAV, COM, AP) works as expected, then it suddenly stop working.

Any ideas ?
