I wouldn't worry too much about it. A couple of years ago, we had a lost comms situation going into MDW where we couldn't hear anything on 130.00 MHz or lower. We immediately squawked 7600 and proceeded VFR towards a different airport that was more practical than MDW. We reestablished comms after being NORDO for about 15 minUtes by using the satellite phone to call ATC and getting a higher VHF frequency that worked. During that 15 mins, we descended and turned off of the airway towards the other airport. When we landed, we had to call the ATC facility manager at MDW. He wasn't happy and said that this would be reported as an altitude deviation to the local FSDO. I told him that we were VFR after losing comms. He said that it didn't matter and that we were to maintain our last assigned altitude. He seemed pretty adamant that our "deviation" would be investitgated to the fullest extent. Long story short, we never heard a peep from anyone...
