Human Factors
Flew VFR and started announcing our intentions 20 miles to the east to land at GUC. On landing didn't see any other traffic. When I set the nose wheel down and looked down the runway here is a [commercial fixed wing aircraft] proceeding toward us on centerline on his takeoff roll. Both aircraft took action to the right of centerline and avoided each other. [Communicated] with Flight Crew; they said their radio was bad and they never heard us.
C414 pilot reports commencing CTAF procedures 20 NM out for landing at GUC with no response from other aircraft. After touchdown; another aircraft is noted taking off in the opposite direction. Each moves to the right and pass on the runway. The other aircraft's crew later reports they had a bad radio.
