Well because I'm a professional pilot, if there were absolutely 0 calls for an extended period, and box two was completely free of animal calls and pilots telling ops their landing times, I would get a radio check. If that didn't come back, I'd 7600, order a tea, and continue enroute.
So you'd sit here with a perfectly serviceable radio, keep it on a redundant frequency, squawk 7600 and continue with your flight plan with no idea of any frequency to change onto that would help everyone in any airspace you will be passing through!
In all this discussion so far you have told us that you are situationally aware and a professional pilot ..... !
No doubt you'll now tell me that I should always carry 2 sat phones and 2 copies of every ATC unit in the worlds number. Proper planning and all that lark.
You now sound just like one of those morons on 121.5
