No clear message can be made out. The carrier wave is too degraded for any words to reach you intact. It could be a ship in distress, or it could be signals interfering with each other. In either case, the captain will prioritize the mission and continue running silent. You try not to shudder and switch frequencies.
Somehow this same choppy signal is on every band, blocking all other transmissions. That can only mean one of two things: either the sender has a whopping huge transmitter, or they are very, very close.
